How Bitcoin Mining Works Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine. Bitcoin is Secure Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure. Links • - Learn all about crypto-currency.

This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. What is Bitcoin Mining? Bitcoin mining calculator will help you to plan your mining income according to your presumed mining difficulties. Bitcoin Profitability Calculator – BTC Mining Profit Calculator. A disruptive technology like ASIC chips could show up and make GPU mining less profitable. Sep 8, 2017 - When Bitcoin started it was made so any average person could mine it on their home computer. Currently difficuly is too high but still there are many coins which can be only mined on CPU/GPU or that are at least still worth it. How do I know it's not like Genesis CloudMining?what's in it for them? What is the Blockchain? Is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a 'subsidy' of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground. What is Proof of Work? A is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements. Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work. What is Bitcoin Mining Difficulty? The Computationally-Difficult Problem Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information. The Bitcoin Network Difficulty Metric The is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes. As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless. The Block Reward When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

(this results are based on my R7 370s tests, but there is a new ethOS update and that will significantly increase the hashrate) In fact, according to statistics, Nvidia is generally less suited for Zcash mining than AMD. It is not yet confirmed whether Nvidia will make the effort to optimize their GPUs for Zcash mining. As for now, if you have Nvidia GPUs in your rig, you might want to switch to a different algorithm than Zcash. There is a tool that might help you to keep your rig mining for the most profitable coin. CryptoCompare offers a useful calculator for both Ethereum (ETH) and Zcash (ZEC). It also supports other coins such as Monero (XMR), Ethereum Classic (ETC), Litecoin (LTC) and DigitalCash (DASH). This calculator is easy to use, and you only should pay close attention to the hashrate you set for your GPU. Sep 24, 2017 Zcash Mining On Cpu - Bitcoin Cloud Calculator bitcoins and different altcoins mining here: Discount Code NVqi5O the. Different GPUs have different hashrates for each of the algorithms, and it is crucial to set it as precisely as possible. The results of the comparison might be surprising. In fact, some miners report that they ended up rolling back to Ethereum Classic, since their GPU ended up giving more profit with Ethash than with anything else.

Institut Katharos - http://gipperich-gipprich-wiki.com/index.php. Terms of SHA256 Cloud Mining Purchase One of the questions many ask, is which Service to go for, Hashflare or Genesis. Its not an easy decision, and the reason for this is that they are largely the same service ie:. Obviously they offer Zcash, Dash and Ethereum etc but the most popular contract is usually Bitcoin. Hashflare set the standard with unlimited lifetime contracts but that recently ceased due to sharp increase in Bitcoin Price. Genesis will offer the Lifetime contract, but on a limited pre-order and with no refunds. With the increasing Bitcoin Price making lifetime contracts near impossible, are, Genesis are also feeling the squeeze. There is no doubt about it, the problem with mining in general is that regardless of Hardware Mining, or Cloud Mining, the price of the mining kit is completely relative to the price of Bitcoin. The shocking truth here is that even the small USB miners from 4-5- years ago (completely unprofitable but good fun) are hitting $60 dollars on the secondhand market. Its is not hard to see why some are still drawn to Mining Ethereum with Graphics cards, as the potential to at least earn the value of you mining rig within in a year is possible. The novice builder beware! Prices of Graphics Cards can also fluctuate, as they did when Litecoin / Scrypt Mining became popular. In fact, many GPU's ended up in short supply. The good points at least is that hardware is holding its value even which could be offset against electricity consumption. Heat is a problem, hence many milk-crate builds. So the question shouldn't be is Hashflare better than Genesis or vice-versa because they are both trying to tackle the same issue which is offering a Cloud Mining Service which is profitable for those who invest, who simply couldn't make a profit with second hand hardware. The risk involved for using Genesis and Hashflare is the same, the terms are clear, no refunds. Depending on the type of mining contract you buy, it will be either fixed term with no maintenance fee's or lifetime with maintenance fee's with no guarantee on profitability or ROI. Whether you're looking to get started in the world of cryptocurrency mining or you're a pro, this calculator can tell you your profit margins based on the current bitcoin mining difficulty and the Bitcoin price (BTC) to Dollar (USD) rate. Just input your hash rate, any pool fees you many incur, power usage, power cost in kw per hour (you can find this on an electricity bill, or look online for averages in your area if you're unsure) and hardware costs if you're using your own rig, or the contract cost if you're using cloud mining, then hit calculate. The results it outputs below are daily, weekly, monthly and yearly estimated profits, along with the amount of time, in days, it will take to breakeven, taking in to account your initial contract fee, or hardware costs. (Cloud SHA-256) Follows Bitcoin difficulty. Cloud Mining Calculator. Number of GHS 4.0. LTC: 0.0077 LTC: 0.0001 LTC. If you're using a cloud mining service, input the cost of your contract. Then click calculate. The results are displayed below, in daily, weekly, monthly and yearly profits. It is based on the current price of LTC to USD, as well as the current difficulty level of Litecoin. It will also show how much time, in days, it will take you to break. What is this? The diff change is the rate at which the network difficulty is changing every month. Diff change is used for the estimated future profits graph and break-even analysis. Typically in crypto, network difficulty tends to increase over time, meaning a miner will generate less crypto with the same hardware. Accounting for this changing difficulty is essential to generate long term profitability predictions. How is this value calculated? The diff change value is calculated by looking at the current difficulty and comparing it to the 12 hour moving average of the difficulty one month ago. For smaller coins the diff change can sometimes be inaccurate due to a wildly fluctuating difficulty. Can I disable it? The diff change factor can be disabled by either manually setting it to 0 or clicking a 'Use Diff Change' switch found below the graph and in the break-even analysis section. What is this? The Break-Even Analysis feature can help you predict how long it will take to become profitable for a given setup. How is this calculated? Time to break-even is calculated by comparing your hardware cost (which you must enter below) to your predicted monthly profits and seeing how long until the initial hardware cost is paid off. The calculator also takes the changing difficulty (diff change) into account. If the network difficulty is increasing quickly, this will greatly increase your break-even time. The diff change can be excluded from the calculation by toggling the 'Use Diff Change' switch. Why is my break-even time 0 or never? If your break-even time is 0 you have likely forgotten to input your hardware cost below. If it is never, your break-even time has been calculated to be greater than 10 years. This is likely due to a large diff change value which causes your predicted profitability to turn negative in the future. You could try lowering the diff change for a less agressive prediction or disable it altogether. What is this? The profitability chart can help you visualize your long term mining projections. The chart can operate in one of three views: Total Profits The Total Profits view predicts what your overall profitability will be in the future. This is calculated by taking your current profits and adding them to each following months profits while factoring in the changing difficulty (diff change), the diff change factor can be disabled. This view assumes the price of the coin will stay the same. If you wish to account for a changing price (ie if you think the price will rise in the future), switch to the 'Coins Generated' view. Coins Generated This view looks at the number of coins you can expect to generate in the future. This view does not account for any expenses, it simply predicts how many coins you will generate with your given hashrate and the diff change value. A high diff change will cause you to generate fewer coins in the future. Total Costs This view sums your power and recurring costs. It can be used to predict the total cost to operate your mine over a given period of time. What is this? Price Change allows you to factor in the changing price of the currency into your projections. You can use this to generate accurate best-case and worst-case projections for your operation. Why does Price Change default to 0? It is impossible to predict what the price of any coin will be in the future, we leave the price predictions up to you. How does this value factor into the calculations? It depends on what Selling Profile is set to. For more details, click on the question mark beside the Selling Profile field found directly below Price Change. What is this? Selling Profile tells the calculator how to use the Price Change value. Price Change must be set to something other than 0 to have any effect on the profitability projections. Selling Profile has 4 different options: Sell Coins Monthly Profitability is calculated as if you were to sell all of your mined coins at the end of each month. Your profits will equal (money earned from selling) - (total expenses + hardware costs) Sell to Cover Expenses Only sell enough crypto to cover your monthly expenses. (electricity, rent, etc.) Your profits will equal (unsold crypto * predicted price) - (hardware costs) Sell a Portion Monthly Selecting this option will show the Sell Monthly field below, this is where you input what portion of crypto you would like to sell each month. For example, if you plan to sell 25% of your new crypto, enter 25 into the Sell Monthly field. Your profits will equal (money earned from selling) + (unsold crypto * predicted price) - (total expenses + hardware costs) Never Sell Coins Select this option if you plan on holding all of your crypto. Your profits will equal (all crypto mined * predicted price) - (total expenses + hardware costs). Hyundai Genesis Coupe on Work Varianza T1S Wheels and more mods.

BTC Cloud Mining Reviews Make sure to check out our reviews before you invest in new hash power. Types of Bitcoin Cloud Mining There are two forms of cloud mining: Hosted Mining — You send your mining machine to a Firm, which provides electricity, cooling and configurations. It is also possible, that you lease yourself a mining machine. Buying Hashing Power — The most popular method of cloud mining — You buy an amount of hashing power Hash Rate. The pros of the bitcoin cloud miner movie are the cons of the other and vice verse. Buying Mofie Power Now let us analyze both the Hosted Mining and the Buying Hashing Power bitcoinn of Bitcoin cloud mining. Starting with the pros of hosted mining: Less Scammy — if you decide to get an hosted bitcoin mining contract, than you need to check if the provider is a registered venture. If this is the case, you have high certainly, that you wont get scammed. Here is a list of hashing power cloud mining scam or terminated contracts. And now the cons of the hosted mining: Higher investment and monthly cost — you not only buy the mining machine but need to calculate your costs of maintaining it, which vary depending on the energy use of the Bitcoin miner. Harder to Monitor — the success can be monitored only partly. Check out our tables above so called monitor tables to see the most profitable ones out there. The pros of the Hosted Mining are the cons of the Buying-Hashing-Power model and vice verse. Bitcoin Cloud Mining Pros Take a look on the benefits of Bitcoin cloud mining: Higher Profits — because cloud mining providers optimize everything, it yields out higher returns. Tranquil and cooler home — no more permanent sound and heat. Less electricity — the electricity bills will get a lot lower. No need to configure the bitcoin hardware. Less risky — the possibility to get let down by the equipment is decreased by a lot. Bitcoin Cloud Mining Cons And now the counterpart list: Scam Risk — you can always have bad luck and find a cloud mining fraud. Cost of Mining Operations — you need to pay for the hardware management Less fun — at least for some it can be less fun to just virtually own something. Lack of control and flexibility — harder to control where to mine or when to sell the bitcoin miner. Jordan Tuwiner Last click June 13, Want to find the best Bitcoin cloud mining contracts. This post has you covered. Most Bitcoin Cloud Mining Companies are Scams Like the heading says, most cloud mining contracts link scams. A company can claim to be a cloud mining company without any proof of actually owning any hardware. Which Companies Are Not Scams. There are only two cloud mining companies we are willing to recommend on this site: Genesis Mining and Hashing Just because they are not scams, however, does not mean that you will make a profit by buying contracts. Hashing24 Hashing24 is one of the few cloud mining companies we are willing to even list here. The main reason is that they are partnered with BitFury, one of most well-funded Bitcoin companies who is also one of the few re-sellers of mining hardware. Hashing24 sells lifetime contracts, so you retain your hash power until the contract becomes unprofitable. For more info, see our Hashing24 review. Genesis Mining Genesis Mining is a Hong Kong based company although its founders are from Germany and attend many Bitcoin conferences. You can read more about Genesis Mining on their about page. Genesis Mining offers three different Bitcoin mining cloud contracts. All plans are paid with a one time payment and are lifetime contracts: Is Cloud Mining Profitable. It depends what your goals are with cloud mining. If your goal is to obtain bitcoins, then there is really no reason to cloud mine or even mine at all. You will get more bitcoins for your buck if you just buy bitcoins. If you think mining is cool and want to try, then cloud mining still is not a good option. Grab a cheap USB miner and run it at home. If you just want bitcoins, mining is NOT the best way to obtain coins. Buying bitcoins is the EASIEST and FASTEST way to purchase bitcoins. Bitcoin Cloud Mining Comparison There is not much to compare, because we personally do not recommend buying any clooud mining contracts so we will not spend the time to compare the two companies above.

The history of high-risk pools and broad expert opinion call all 2000 this optimism into doubt. People with medical conditions may need this help if they have a lapse in coverage. Under the Republican bill, states could get waivers that allow insurers to charge higher premiums to those customers, but only if they have a gap in coverage and if the state has a mechanism such as a high-risk pool to support them. It leaves out Medicaid expansion. Altogether, those measures cover more people than the number who claimed exemptions from the mandate 200 obtain health insurance or who paid a penalty for lacking insurance. Last year, nearly 13 million people claimed exemptions from the mandate to obtain health insurance, citing financial hardship or other reasons, and 6.

As just one example, people were forbidden from giving or receiving religious items at a military hospital where our brave service members were being fom, and when they wanted those religious items. A poorly worded policy in indeed appeared to ban Bibles and other religious items from being handed out or used during visits, but hospital officials say that was not the intent and it was never enforced. The aim was to stop visiting benevolent groups from proselytizing to patients, after complaints arose that wounded service members were being harassed by some of them. The policy was clarified after about four months.

But just what is Bitcoin, how do you get some, and can you manage it on your Android. But one thing for sure is Satoshi Nakamoto is a cryptographic genius. As a digital currency you would think it would be easy to generate fake Bitcoins or spend the same Bitcoin twice. Every Bitcoin created has a cryptographically generated digit address. Each Bitcoin also has a public key and a private key that unlocks its cryptographically generated addresses. In order to spend your Bitcoins their address must be verified using the public and private keys by a series of decentralized servers laptops, desktops, dedicated servers, and, increasingly, smartphones all over the planet. Because of the advanced cryptography, the verification of these Bitcoin wallets by decentralized servers known as mining is a very processor-intensive and time-consuming task. But it also adds a layer of security and confidence in this digital currency. Bitcoin servers are connected via peer-to-peer networks, much like torrent networks, so no centralized server exists. What is a Bitcoin worth and where can I spend them. Right now, Bitcoin will make you rich—if you got in early. Yeah, I want a time machine too. Bitcoin has been on a wild ride this year. At the time everyone thought that was huge. But Bitcoin prices fluctuate wildly, and if you buy them on an exchange and get in at the wrong time, you can lose a ton of money. However, many now believe the value of Bitcoins can soar ten to a hundred times their current price. But as Bitcoin has risen in prominence, now major websites like Reddit, WordPress, Baidu and several retailers are taking the currency. How do people get Bitcoins. You can buy them, or you can mine them. Mining will get your free Bitcoins as rewards for using your hardware to calculate the complex mathematical problem resulting in a digit answer that is required to verify a Bitcoin is legitimate. For every algorithm you solve you are awarded a block of 50 Bitcoins. This means that the more people that try to mine, the harder it is to get Bitcoins in other words, more processing power is needed to crack advanced math problems. This helps keep the currency valuable. Right now about 11 million Bitcoins exist, which means only another 10 million can be mined. It may also be limited to a specific market, whether local, regional or national. For example, the UAW and the 'Big Three' American automakers tend to operate in this pattern: In the United States in particular there has been pressure from the employing class generally on this. Strategy[ edit lablr When negotiating a master contract, the union often selects the financially strongest employer or worksite to negotiate with it. This agreement becomes the master contract, and sets the pattern for bargaining with the other employers or worksites. In Canada, unions have used master contracts to organize thousands of new workers. A master agreement has tended conract weaken an employer's resistance to the spread of the union to unorganized mining contract labor or divisions, and some industries and markets welcome mining contract labor standardization of pay and fringe benefits that unionization brings.

Why Was This Created? There are a lot of calculators out there already, but I couldn't find one that allowed me to calculate compounded reinvestments. Also, their calculations are not precise since they assume that the mining difficulty doesn't change over time, the Bitcoin to USD price remains the same, and they also do not minus maintenance fees. So when you're trying to check how much a Crypterra contract would give you in a year, most likely others would show you very high and unrealistic returns.

Lastly, to be honest, I also wanted a way to get by creating a tool that people may find helpful:) - Benjamin. What is this? The diff change is the rate at which the network difficulty is changing every month. Diff change is used for the estimated future profits graph and break-even analysis. Typically in crypto, network difficulty tends to increase over time, meaning a miner will generate less crypto with the same hardware. Accounting for this changing difficulty is essential to generate long term profitability predictions. How is this value calculated? The diff change value is calculated by looking at the current difficulty and comparing it to the 12 hour moving average of the difficulty one month ago. For smaller coins the diff change can sometimes be inaccurate due to a wildly fluctuating difficulty. Can I disable it? The diff change factor can be disabled by either manually setting it to 0 or clicking a 'Use Diff Change' switch found below the graph and in the break-even analysis section. What is this? The Break-Even Analysis feature can help you predict how long it will take to become profitable for a given setup. How is this calculated? Time to break-even is calculated by comparing your hardware cost (which you must enter below) to your predicted monthly profits and seeing how long until the initial hardware cost is paid off. The calculator also takes the changing difficulty (diff change) into account. If the network difficulty is increasing quickly, this will greatly increase your break-even time. The diff change can be excluded from the calculation by toggling the 'Use Diff Change' switch. Why is my break-even time 0 or never? If your break-even time is 0 you have likely forgotten to input your hardware cost below. If it is never, your break-even time has been calculated to be greater than 10 years. This is likely due to a large diff change value which causes your predicted profitability to turn negative in the future. You could try lowering the diff change for a less agressive prediction or disable it altogether. What is this? The profitability chart can help you visualize your long term mining projections. The chart can operate in one of three views: Total Profits The Total Profits view predicts what your overall profitability will be in the future. This is calculated by taking your current profits and adding them to each following months profits while factoring in the changing difficulty (diff change), the diff change factor can be disabled. This view assumes the price of the coin will stay the same. If you wish to account for a changing price (ie if you think the price will rise in the future), switch to the 'Coins Generated' view. Coins Generated This view looks at the number of coins you can expect to generate in the future. This view does not account for any expenses, it simply predicts how many coins you will generate with your given hashrate and the diff change value. A high diff change will cause you to generate fewer coins in the future. Total Costs This view sums your power and recurring costs. It can be used to predict the total cost to operate your mine over a given period of time. What is this? Price Change allows you to factor in the changing price of the currency into your projections. You can use this to generate accurate best-case and worst-case projections for your operation. Why does Price Change default to 0? It is impossible to predict what the price of any coin will be in the future, we leave the price predictions up to you. How does this value factor into the calculations? It depends on what Selling Profile is set to. For more details, click on the question mark beside the Selling Profile field found directly below Price Change. What is this? Selling Profile tells the calculator how to use the Price Change value. Price Change must be set to something other than 0 to have any effect on the profitability projections. Selling Profile has 4 different options: Sell Coins Monthly Profitability is calculated as if you were to sell all of your mined coins at the end of each month. Your profits will equal (money earned from selling) - (total expenses + hardware costs) Sell to Cover Expenses Only sell enough crypto to cover your monthly expenses. (electricity, rent, etc.) Your profits will equal (unsold crypto * predicted price) - (hardware costs) Sell a Portion Monthly Selecting this option will show the Sell Monthly field below, this is where you input what portion of crypto you would like to sell each month. For example, if you plan to sell 25% of your new crypto, enter 25 into the Sell Monthly field. Your profits will equal (money earned from selling) + (unsold crypto * predicted price) - (total expenses + hardware costs) Never Sell Coins Select this option if you plan on holding all of your crypto. Your profits will equal (all crypto mined * predicted price) - (total expenses + hardware costs).

The following guide is a comprehensive tutorial on GPU mining from planning through execution. It will cover not just the technical setup but the decision making and process regarding profitability and long term gains. Table of Contents: 1) Planning 2) Hardware & Equipment 3) Environmental Considerations 4) Assembly 5) OS & Mining software 6) Wallet Storage 7) Conclusion 1. PLANNING 1.1 What to mine 1.2 Electrical costs 1.3 Profitability & ROI 1.4 Up-time 1.5 Monitoring & Alerts 1.6 Scalability 1.1 What to mine Not all GPU’s are created equal. Some GPU’s mine certain algorithms/coins better then others. For example, NVIDIA GPU’s are better at mining Zcash while AMD GPU’s are more successful mining Ethereum. It is important to decide what you want to mine before purchasing or sourcing your GPU’s. Currently Ethereum is the most profitable coin to mine however at some point it will go from Proof of Work (mining) to Proof of Stake. At this point those mining Ethereum will need to move to another algorithm. The good part about GPU’s is that unlike ASIC miners, they can mine any algorithm (although some more successful then others). So switching gears is not as difficult as one might think and we should see future coins using the Proof of Work model. As of the writing of this guide (Sept 2017) Zcash or Ethereum is the way to go. There are also multi mining pools and platforms such as that will pool your GPU Hashing power and automatically switch to the most profitable coin. Here are some resources to help you make an informed decision. Reddit, Steemit, and of course the BitCoin Pub mining section are all great resources to ask questions for up to date awnsers. Mining is not static! It is evolving monthly. So if you are unsure post a question! 1.2 Electrical Costs When it comes to mining, there is more to consider then simply how much coin you can mine in a given period. GPU hardware running 24/7 consumes quite a bit of power. If you dont factor in your electrical costs you may actually be losing money when your utility costs monthly are higher then the amount of coin you are mining. Power costs fluctuate DRASTICALLY depending on where you are in the world. In some areas, it may not be profitable at all to GPU mine. I live on the U.S. East coast where power costs are pretty inexpensive 0.10 KW/h. You can find your power costs on your utilities bill or by calling your electric company. In many areas electrical costs are negotiable! In the united states many states have deregulated energy and you can by power through a re-seller at a discounted rate. Before mining look into energy reseller alternative in your area. To determine if GPU mining will be profitable, enter your power costs and hash rates into this calculator: Find out what your expected return is depending on your hash rate and electricity cost. Find out if it's profitable to mine Bitcoin, Ethereum, Litecoin, DASH or Monero. Do you think you've got what it takes to join the tough world of cryptocurrency. 1.3 Profitability & ROI When mining, there are 2 important factor. How long will it take for you to get a return on investment (ROI) and how profitable is your mining operation. It is important to be conservative when doing these calculations as your GPU mining rig will become less profitable over time as the mining difficulty increases. Your ROI is very simple. How Many days will you need to mine to reach profits that equal your initial hardware investments. Here is a basic example. Hardware Costs: $3000 Total Hashing power: 230 MH/s Total Power Consumption: 800W Daily profit: $12.25 $3000/12.25 = 245 Days to ROI* Additionally, These GPU’s we use to mine are extremely powerful and great for gaming. These cards have excellent resale value and there is a large market for them. After 12-24 months you can conservatively resell the cards for 20-50% of their retail value to help offset the difficult increase and claim your ROI. Profitability is the second factor and there are 2 considerations. How much coin you mine and the interest/market growth of that coin. You obviously will want to mine as much coin as possible, which we’ve covered in the “what to mine” section. But we also need to consider the long term growth of the coin we mine. Some mining pools will allow you to be paid out in BitCoin. This may be helpful if you plan to invest your profits in to alt coins. You also want to be smart with how often you take your mining payouts. You may be charged fees per payout or fees for payouts under a certain threshold. You want to avoid transaction fees cutting into your profits. Best practice would be to read all the guidlines on payouts and fees from the mining pool you are using and to take payouts infrequently either monthly or quarterly. You may find you will be much more profitable taking payouts less frequently and you may see more growth with your profits coming out in BTC or investing in an altcoin you believe in (NEO, OMG, TenX, Monero, etc) 1.4 Up-time When it comes to mining, NOTHING is more important then up-time. Every minute your mining rig is offline you are losing money. So it is CRUCIAL to build redundancy into your design as well as invest in materials and testing to repair your rig if/when something fails. As with any 24/7 operation, you’ll need to weed out single points of failure. Some considerations are: -GPU failure -PSU failure -Motherboard failure -Peripheral failure -OS corruption -Power outages -Internet outages GPU Failure: The most common failure in a mining rig is hardware. By design, mining rigs have multiple GPU’s, so we don’t need to worry about redundancy there as you will already have 5-10 GPU’s per rig. It is important however to thoroughly review the warranty and RMA process for your GPU hardware and contact manufacturer support so that when the time comes you know the steps and the process to get your GPU replaced. MotherBoard Failure Motherboards are durable equipment without many/any moving parts that typically either fail out of the box or are durable for the lifetime of the board. That said, if your motherboard does fail, you are going to be losing money every second it is offline. Another consideration in larger mining rigs (6 or more GPU’s) is running all your GPU’s off of one motherboard. I think it is wise to shy away from motherboards with 10-18 PCIE slots. If your motherboard failed and you were running 16 GPU’s on it your ENTIRE mining operation would go offline. Where as if you had 2 motherboards if your board failed you would still be able to mine half your GPUs while the other is being swapped out. Motherboards are stocked in many computer stores and readily available with next day shipping from most online resellers such as Amazon and NewEgg. However you want to be able to quickly swap out a bad board to limit mining down time. With the relatively low cost of motherboards ($50-80 in most cases) it is wise to invest in a second motherboard. Be sure to always test your backup hardware. A backup motherboard does you know good if its DoA/a lemon and you realize your mining rig will still be down. So test that backup hardware! Peripheral failure: Like with motherboards, you dont want your mining operation to go down because your hard drive failed, PCIE risers failed, or you have a bad cable or RAM. These peripherals are inexpensive and you should plan to have a spare on hand of each peripheral. PCIE risers in general are susceptible to failure overtime. For less then $60 you should be able to have a replacement of all your peripherals. As a wise man once told me “It is better to be looking at it, then to be looking for it” OS Corruption: It is not uncommon, especially in Windows builds, for the OS to become corrupted or other software/OS issues to can cause downtime in your mining rig. There is a simple way to combat OS corruption. Backup or clone your hard drive. Once you have your rig fully configured and mining either clone your hard drive or make a backup image. There are plenty of free or low cost options for cloning or imaging software such as Acronis True Image and EaseToDo Cloning software. I personally like to clone my drive to a spare drive which protects against both OS corruption AND hard drive failure. It is also a great practice to either record your GPU/hardware/software settings or if your drivers allow it export the settings or export a profile so you can easily restore it if needed in the future. Power & Internet outages: Power and internet outages are mostly out of our control. But there are steps we can take to minimize the impact. It is strongly recommend to have your mining rig plugged into an uninterruptible power supply(UPS). A small APC UPS can be purchased for as little as $30 even cheaper if purchased through secondary markets. While the UPS will NOT keep your mining rig up during a long power outage, it will afford you the time to gracefully power down your rig so that an unexpected power outage does not cause a surge or damage to your GPU hardware. Internet outages will also halt your mining operation. It is a good idea to have a secondary cheap router on hand in the event your router fails. A router can be purchased on the secondary market for as little as $5 or $10. While you CAN get a redundant secondary ISP, it is not worth the cost as this will incur more monthly recurring costs cutting into your profits and ISP up-time is generally in the 97-99% range. Instead it may be worth while to have a second site/location you can bring your rig too during an ISP outage or disaster (a flood or fire at your current location for example). 1.5 Monitoring & Alerts Having built in redundancy and a good disaster recovery plan are great steps to ensure your mining rig stays up and online. But all that planning wont help if you dont realize your mining rig is down. It is important to setup email or text alerts anytime your rig is down or stops mining. Most mining pools have a built in function that you can configure to send you a text or email alert anytime the pool detects you stopped mining. Likewise you can should set alerts with in windows, your UPS, any any other hardware capable of denting outages so you can quickly resolve the issue. Please use the forum to help with any questions on configuring hardware, software, and service alerts. 1.6 Scalability When planning your mining rig, it is important to consider how you may want to scale the operation in the future. Building the infrastructure of your rig in a modular way allows you to scale the build more easily as well as upgrade components over time if necessary. Building a stackable rig for future implementation is important when discussing scaling. Designing a Bottom shelf with clearance and airflow for example is important if you plan to stack a second rig on top of the first one. Another important consideration is your space. Do you have the space to grow your operation physically? Do you have the appropriate cable lengths and network infrastructure to grow the rig? Do you have the proper cooling environment to handle a large scale operation? This planning should be done prior to the purchase, buildout and implementation of any rig. Pro-Tip: Check out post on electrical requirements. HARDWARE & EQUIPMENT 2.1 Open Air frame 2.2 GPUs & PSUs 2.3 Motherboard and perifpherals 2.4 Cable Management 2.5 UPS 2.6 Environmental protection and cooling 2.1 Open Air Frame Other then your GPUs, your frame may be the most important thing your purchase and design. Temperature control, cooling, scaling, repairs, and upgrades are all heavily reliant on a well assembled well designed open air frame. While your rig doesnt need to be pretty or a Picasso-like work of art it does need to be functional and allow for cooling, growth and maintenance. The best open air designs seperate components out, allow for proper air space, and are designed in a way that you can easily get to all component in the event in which they nee to be swapped our or repaired. There are a few considerations here and while there are dozens of great designs I will be presenting one in which I believe covers all the bases, You’ll want to choose a good material: -Something that conducts heat well -Something that is light and can be easily moved -Something that is cost effective -Something that isn’t prone to produce dust or particles Lightweight metals such as aluminum are a great choice. Aluminum tubing and aluminum angle are lightweight, cost effective, available at most hardware stores, and dont produce dust or particles that may get sucked into a fan intake. While aluminum angle is easily assembled, I prefer the modularity of aluminum tubing with connectors. Is a great online source for aluminum tubing and connectors. The snap in connectors make it easy for anyone to quickly assemble a sturdy box-type frame. The materials can but cut to custom sizes and is fairly inexpensive. I built a 24 X 18' custom cut 2 tier frame for less then $65 including shipment. A good open air rig is more then just the box frame. You will want to have 2 tiers. An upper tear for your graphics cards and a lower tear for your motherboard, peripherals and power supply. The bottom shelf should be sturdy and be braced. This will reduce vibrations which can lead to wear and tear or damage over time. As you can see from the photo above we attached 3 pieces of 1/4' thick aluminum across the bottom of the box frame to help brace the shelf. For the shelf you want to use something sturdy. We chose a 1/8' piece of stainless steel sheeting. This has the weight to remain sturdy and reduce vibration from the equipment running on it. Since this is our first rig there was no consideration for air flow on the bottom shelf. However if this was a second rig, we would instead use a perforated steel sheet for airflow for the GPUs stacked on the rig below. You will also want to stabilze your components. Drilling motherboard standoffs into the steel base will allow to attach your motherboard and provide airspace for it so it doesnt come in contact with the steel which could cause a short. You can also use the Aluminum angle to create a bracket to hold your PSUs in place. The Top Shelf should have a ledge or flange for the GPU to screw into as well as a rear crossbar to support the back of the video card and hold it into place. To achieve this you can attach a piece of Aluminum angle across the frame. 2.2 GPUs & PSUs GPUs and PSUs are the most important hardware components of your mining rig. For GPUs there are several considerations. We already covered “what to mine” in section one and will now focus on which GPUs are the most reliable and profitable for current and future mining. There are 3 major considerations: -The initial investment (Cost of the GPU) -The Hashrate vs Power consumption Ratio -The long term mining ability. Initial Investment How quickly you reach your ROI is directly proportionate to how much you spend for GPUs. While GPUs are still somewhat tough to source at cost/without a market things have settled down to where you can find most cards retailers or through online stores. While one GPU may drastically outperform another, it may make sense cost wise to go with another GPU. For example if you are able to buy TWO GPUs with a 18 MH/s output for $20 each that may be a better option then buying one card with a 35 MH/s rate for $500. So keep initial cost of hardware in mind when making this decision. This will vary quite a bit depending on where you live and what options are available to you at the time. Hashrate vs Power consumption Ratio There are a few different philosophies on Hash vs. Power Consumption which are influenced not just by opinion but by area. If your power costs are low (or free) Hashrate become most attractive. Additionally with difficulty going up over time, hashing as many coins as possible in the early stages is also a consideration. If you live somewhere with high power costs, power consumption becomes critical. For this guide we will assume all things are equal. Below is a chart of viable GPUs from a Hash vs. Power perspective sorted by hashrate (no necessarily by best ratio) AMD Radeon R9 295X2 - 46 MH/s @ 325 W AMD Radeon RX VEGA 64 - 40 MH/s @ 165W NVIDIA GTX 1080 Ti - 32 MH/s @ 125W NVIDIA GTX 1070 - 27 MH/s @ 105W AMD RX 580- 22 MH/s @ 75W AMD RX 480 - 20 MH/s @75W *** Disclaimer. These rates are subject to change and may vary based on driver and bios configurations. There are tons of resources on hashrates. Please do your own research and check the mining forum for real life results people are getting. *** I’ve personally tested both the GTX 1070 and AMD RX VEGA. I find these to be the most measurable, cost effective GPUs that provide high hash rates with reasonable power consumption. Please check out my AMD RX VEGA mining rig breakdown here. Finished building my new open air frame. No longer on the rickety wooden shoe rack of a rig Aluminum tube frame with aluminum angle holding the back of the cards and a stainless sheet on the bottom shelf didnt seem right all silver and blah so i gave the frame a coat of metallic black and some cherry red on the steel to make it match the VEGA’s More pictures to come Were mining at 215.75 MH/s @ 1055W the HP server power supplies are ton more efficient then the gold PSU we The RX Vega and GTX 1070/1080 are both great long term mining options. There may be better alternatives or better options based on your situation (Budget,environment, power costs). Please do your research or consult the forum to help make this decision. Long term mining ability. Just because a GPU mines well now does not mean it will continue to mine well in the future. There are 2 major considerations when considering long term mining ability. Difficulty and Dag. Over time as coins are mined the difficulty of the algorithms increase. This is a sort of check and balance put in place on the block chain to ensure the security of the ledger and that no single entity can manipulate the blockchain. For more on this, read the bitcoin white paper or read up on how proof of work functions. The important thing to keep in mind however, is that the difficulty WILL increase. So you will want as much hash power as you can get. Whether that is achieved with scale (many GPUs) or Raw power (GPU hash rate) you want to try and squeeze as much hashrate as you can out of your rig while remaining profitable in respect to power consumption. The second, and more important consideration is the DAG (Directed Acyclical Graph). The DAG basically maps out the algorithms and instructions. It must be loaded into memory almost like a header. Why is this important? Because the DAG grows at each increment. These increments are called “Epoch” and come in 100 hour increments. At a certain point, a GPU will not be able to fit the DAG into memory this takes quite some time, however in the near future (at approximately epoch 199 or 200) cards with only 4 GB of GDDR5 RAM will no longer be able to handle the DAG and will not be able to mine Ethereum. Additionally, as we approach Epoch 200, the DAG will consume more and more of that 4 GB of RAM cutting into the hashpower of 4 GB GDDR5 RAM GPUs. What does all of this mean? In Short: Make sure your GPUs have 8 GB or more of memory. One consideration of going with the AM RX VEGA was its 8 GB of HBM2 memory. RX 480/580 card models with 4 GB of memory are now flooding the secondary market. If you plan to mine, stay away from those 4 GB models. PSUs are the other important hardware component. This is not only going to power your rig and keep it online, but also factor into your energy costs. All PSUs are not created equal. Some are much more energy efficient then others. It is also important to understand how much power your need. There are 3 major considerations when choosing a PSU: -Durability/output -Efficiency -Cost Durability/Output If your Rig is going to draw 1000W you dont want a 1000W power supply, you want more juice then that as PSUs are not designed to run on their maximum load 24/7. You can refer to this site to help calculate your power consumption and how big of a PSU you will need. !!!THIS IS A MUST READ IF YOU PLAN TO MINE OR CURRENTLY MINE!!! I’ve been reading on a lot of different forums (prior to TheBitcoin.Pub) and even on our own forum about people not knowing the electrical needs of their GPU mining rigs. I’m here to tell you that and I have spent a lot of time researching and implementing what it takes to get multiple rigs up and running. We have contacted electricians and even consulted with electrical engineers. This information is GOLD please stick with Efficiency PSUs are typically rated into 4 categories: Bronze, Silver, Gold, and Platinum. Bronze being the least efficient and Platinum being the most efficient. Why is this important? Because the more power you waste/use the less profitable your mining rig will be. PSUs convert AC current from the wall and convert it to DC power for your rig. During this conversion there will some power loss. This also produces more heat. The higher efficiency power supplies require less AC current to produce the same amount of DC power and produce less heat. (which is also important as many GPUs hash better at lower temperatures). You can Save 5%, 10%, or even 20% on energy costs with a Gold or Platinum PSU. Resource: Cost The last factor is cost. PSUs, especially the gold rated ones, can cost up to $200 or more. The more you spend on a PSU, the more profit you need to make to reach your ROI. And as mentioned in the Redundancy/Single point of failure portion of Section 1 above, you are going to want to have multiple PSUs in your mining rig. So choosing the most cost effective PSU and balancing that vs. The most efficient PSU is an important calculation. Instead of purchasing an expensive high end gaming PSU, purchase an old server PSU. Server PSUs are built to run 24/7, are platinum rated, and are very inexpensive ($15-$35). You can purchase a Pair of 1000-1200W PSUs to power your GPUs and a 225W PSU to power your motherboard all for under $100. Sells HP proliant PSUs here: Important! You will also need a breakout board. Server PSUs attach modularly to server motherboards. In order to get 6 pin PCIE interfaces you will need a breakout board. The X6 breakout board is available on both ebay an parallel miner: 2.3 Motherboard and peripherals Purchasing the right motherboard is very important and it is easy to mistakenly buy something that appears to meet the needs of your mining rig but falls short. For example, a 6 card mining rig will require 6 PCIE slots in order to run all 6 cards. There are plenty of motherboard that come with 6 or more PCIE slots. The problem is a lot of these motherboard are not made to handle 6 GPUs running simultaneously and while they can run 6 PCIE devices at the time they weren’t designed with GPU mining in mind. They were designed to handle a couple of graphics cards in addition to other PCIE devices such as RAID controllers, NIC adapters, Card readers and other PCIE interfaced hardware. Luckily, with the expansion of GPU mining, hardware manufactures have started making motherboards specifically geared towards GPU mininig, ASRock, BioStar and others make several boards designed to handle 6+ GPUs, and even have “BTC” in the model name. While you don’t need a motherboard marketed as a “BTC” or “Minining” motherboard to run your rig you should do extensive research on whether or not the motherboard you choose can handle the GPUs and has shown to be stable running multiple GPUs 24/7. Resource: The following is a list of some of the more popular mining motherboards: 7gpu motherboard, 8 gpu motherboard, 6 gpu motherboard, mining motherboard, z170 7 gpu, best gpu for ethereum 2017, asus h170 pro gaming. As mentioned in section 1 with regards to redundancy and uptime; I would suggest against motherboards with 10+ PCIE slots to run that many GPUs all on one board. Not because the board can not handle it, but because if you do have a motherboard failure you bring your entire operation to a halt. Now that you have all the main components of your rig mapped out, its time to look into the peripherals, bells, and whistles you will need to connect all the components and optimize your design. At a minimum you will need: -PCIE Risers -PCIE/Molex/Sata connectors. -Hard drive/storage -RAM/Memory -Processor PCIE Risers are extension cables that connect your GPUs to your motherboards PCIE slots. Remember the reason we are building this open air rig is for cooling and airflow so housing your GPUs right in the motherboard would not allow for that cooling and likely overheat your rig. The risers allow you to secure the GPUs on the upper shelf, where air can flow more freely. There are alot of PCIE risers on the market and most of them are made cheaply and are the component most prone to failure in your rig. It is recommended that your purchase a few spare risers so you minimize downtime in the event of failure. PCIE risers come in both powered and non-powered versions. It is recommended to use the powered versions over the non-powered 16 pin ribbon cables. The powered versions require less power from your motherboard and from a durability perspective are going to keep you up and running longer. The powered versions are also required for many rigs as most multi PCIE slot motherboards dont have full 16 pin PCIE slots for of their interfaces. PCIE/Molex/Sata cables Most PSUs and GPUs will come with cables and connectors. But you may not have enough cables to connect all your GPUs or more important connect them all with individual cables. (Running more then 2 GPUs in series is not recommended and likely to cause issues down the road). If you go with the above recommended route of using HP server PSUs with breakout boards, you wont have any cables included and will need to purchase several 6 pin to 6+2/8 pin cables/connectors. Overall you will want to do a review of all the cable and interface/adapter needs for your components and make sure you have all the required cables. You will also want a few spares for troubleshooting or replacement and most importantly be sure to get the correct lengths so that your cables reach your hardware and arent being stretched. Hard drives/Storage GPU mining rigs require minimal storage. You will need a drive to run your operating system and GPU hardware. Windows 10 requires 16 GB of drive space for its installation. With software and formatting you can easily get away with a 64 GB hard drive for a windows OS based mining rig. Linux based rigs can run on even less or even run off a usb stick. 64 GB 2.5' or mini PCIE hard drives can be purchased for as little as $35. As mentioned in section one, buying a second drive and cloning your rig after initial tested stable setup or having a backed up.ISO image ready to go for recovery is strongly recommended. RAM/Memory While GPU RAM/Memory is crucial to the performance of your mining rig, system RAM/Memory is not critical at all. A 4 GB stick of RAM will be enough to power your rig without any issues. With the cost of RAM being so inexpensive, and for redundancy reasons, it is recommended to buy two 4 GB sticks of RAM, keeping your rig operational should one stick fail. A 2 x 4 GB RAM kit will run you as low as $30. Processor Like system RAM, mining rigs do not require A lot of processing power from the CPU to operate. In fact, it is more profitable not to run a powerful CPU as it wont increase mining performance but will increase your power costs. Using a Pentium or Celeron processor is going to provide all the processing required while consuming less power then an i3/i5/i7 processor and also save you quite a bit of money in hardware costs. Be sure to keep this in mind when choosing your motherboard to ensure the socket can handle the processor you choose. 2.4 Cable Management Cable management should be considering for any mining operation, especially larger multi rig operation are those expected to scale overtime. Beyond just satisfying those of us who are OCD when it comes to organization, proper cable management while allow you to more easily access components or swap hardware in and out more efficiently. As we have covered several times already, you are losing money every moment your rig is down. To e able to quickly swap hardware and cabling in and out is an important design consideration. Some best practices for cable management include: -Use cables of appropriate length, with enough slack to prevent pulling but not so much that it will coil up and tangle. -Use velcro in place of tie wraps whenever possible. Velcro allows for easy removal and recabling where ties need to be cut. -when cutting the excess of a tie wrap, be sure to cut right at the knuckle to avoid sharp edges that could cut wiring -use your frame to secure and space your cables out evenly and channel them to the appropriate areas. -Avoid crossing cables across the rig, and design your rig so that components connected with cables are closest to eachother. 2.5 UPS A UPS (uninterrupted Power Supply) is strong recommended for all mining rigs. A UPS will NOT keep your mining rig running through a power outage what it will do is allow you to gracefully and safely shut down all the components of your mining rig so that a power outage and sudden shutdown will not damage any of the components. Protecting your investment is critical. You dont want to be caught setting up an RMA or warranty claim on a GPU that failed during a power outage nor do you want your rig down while you wait 7-10 business days for a new one to arrive. A 1500W power supply can be purchased for as low as $65. Most UPS also have the ability to set up email or text alerts that will notify you of an outage which is a nice feature to have. 2.6 Environmental protection and cooling Once you have your rig set up and running it is important to protect your rig against its surroundings. Depending on where you store your rig, you may need to worry about things such as dust, debris, moisture,and other elements. Some considerations and failsafes to consider are: -to keep your rig in a cool, dry area. -keep your rig elevated off the ground in the even of a spill or flood.whether on a shelf or even building your frame out with legs to elevate the shelves. -To protect against dust and debris you can line the frame of your rig screen door screen which will allow air flow while cutting out dust and particles. Covering fan intakes with pantyhose is an old IT hack that many people still employ that also keeps dust and particles out. -Use compressed air to blow any dust or debris out of your rig on a periodic basis. In addition to keeping your rig dry and clear of debris, proper cooling is also important especially in larger scale multi rig mining operations. While the subject of cooling is vast and beyond the scope of this guide it is important to know that keeping your rig cool is critical not only to keep it from overheating or causing damage but a lot of high end GPUs will also have increased hash rates at lower temperatures. Channeling heat away from your rig with duct or tubing, fans, or vents can make a considerable difference in how cool your rig will run. While air conditioning is a very effect way to keep your rig cool, be sure to consider the power costs of running air conditioning 24/7, as this may cut into your overall profits or even put you at a loss depending on the power consumption of the air conditioning and electrical costs in your area. ENVIORNMENTAL CONSIDERATIONS 3.1 Where to store your rig 3.2 Power requirements 3.3 Building to Scale 3.1 Where to store your rig Choosing where to store your rig is important as the environment will be integral in ensuring that our operation stays online and is protected against hazards. Like any electrical equipment, it is best to keep your rig in a cool dry place to prevent against moisture damage or overheating. You’ll want to store your rig somewhere with: -Ample space for airflow -Good ventilation -temperature control -free of dust and debris You’ll also want to keep your rig elevate off the floor to protect against any floods and potentially enclose your case to protect against debirs. This will be covered in more detail in the hardware and assembly sections of this guide. Electrical Wiring - Most houses are build using 14 AWG electrical wiring. 14 AWG electrical wiring is designed to handle electrical loads up to 15 amps per building codes. Any amperage over that will cause the shield around the wires to melt due to heat. If you are using a 1500watt PSU, it is probably rated for a 15amp input. So you are probably thinking, “I’m good”, no. That maximum load on the wires isn’t made to handle that load 24/7. Typically, electrical engineers would recommend only going to about 80% of the full load. Also, lets say you want to run multiple GPU mining rigs in the same room, you MUST verify that all the outlets in the room are ran in parallel and not in series. Layman’s terms, each outlet directly feeds back to the breaker box. Otherwise your rigs will be running on the same circuit and you will overload the wiring and the breaker. Consult with a certified electrician about installing 12 AWG electrical wiring on 20 amp breakers if you are going to build more than one GPU rig. Extension cords - PLEASE DON’T USE EXTENSION CORDS! Read the warning labels on the extension cords. They are not made to handle the continuous load that the GPU mining rigs demand. Extension cords are designed for temporary use only. I have seen extension cords overload or malfunction and pop (Christmas 2016). The complete guide can be found in the Mining & Hardware support forum. !!!THIS IS A MUST READ IF YOU PLAN TO MINE OR CURRENTLY MINE!!! I’ve been reading on a lot of different forums (prior to TheBitcoin.Pub) and even on our own forum about people not knowing the electrical needs of their GPU mining rigs. I’m here to tell you that and I have spent a lot of time researching and implementing what it takes to get multiple rigs up and running. We have contacted electricians and even consulted with electrical engineers. This information is GOLD please stick with 3.3 Building to Scale When considering your environment, it is important to plan things for future growth if you intend to scale the operation. The needs and requirements to run 25-50+ GPUs is drastically different then running just 5 or 6 GPUs. Your electrical infrastructure, storage, cooling, and potentially even zoning and permit requirements will need to be planned in accordance with how large your operation may grow. It is recommend to consult with an electrical engineer and potentially even your town or city for guidelines on scaling your operation to something of commercial size and power needs. ASSEMBLY 4.1 Frame assembly 4.2 Prepping for components 4.3 Component installations 4.4 Cabling 4.5 Disassembly and testing 4.6 Customization 4.1 Frame Assembly 'Measure 10 times, cut once' -Someone really smart This old proverb needs to be running on loop in your head the entire time you assemble your frame. Spacing out your frame to properly hold your GPUs is really important. You need to make sure your GPU measurements as close to exact as possible when ordering/cutting your material lengths. If you are using the above recommended tubing and connectors from “Esto Connectors” you need to be sure to factor in the 3/4' added to the length by the connectors. It may also be worthwhile to make a full scale model out of scrap wood or cheap plastic to make sure you get the measurements right. When building my first rig, i used some left over 1 x 1 pieces of wood left over in my garage to build the top shelf of my rack to get an exact measurement for the spacing on my GPUs. Once you have your prototype it is easy to get the exact material lengths and purchase or cut those materials. From there it is just some screws and/or elbow grease to get your frame assembled Once assembled, verify once more that your components and GPUs will fit properly. The last thing you want to is to start cutting/installing shelves and brackets to find out you made a cutting error and it wont all fit right. 4.2 Prepping for components While most of the hard work is measuring and building the initial frame, there is prep work still needed to properly install your hardware components. You’ll need to consider the following: -Screw holes will be needed to attach the front of your GPUs to the frame and hold them in place -A rear support will be need to support the weight of the GPUs -Braces and a bottom shelf will need to be installed to hold your motherboard and power supplys -motherboard standoffs will be needed to secure the motherboard and rise it above the shelf -angle brackets are a great way to secure PSUs into place Before drilling the screw holes for your GPUs, space them out and mark where they will all go to ensure even spacing and proper airfflow. Using a cardboard template of the width of your GPU can be helpful in this instance. Once marked drill the holes to the width of the screws you are using (i used #6 machine screws). After drilling each hole, secure the GPU to test fit and angle. Then remove the GPU and move on to the remaining screw holes. While some designs will use the frame itself to support the back of the cards, you may want to install something a bit more modular that can be more easily adjusted. A piece of aluminum angle installed horizontally across the top tier is a great fit to support the rear of the card while maintaining some flexibility should end up swapping out GPUs or add additional GPUs with a different form factor. Some designs will support the GPUs by using shelves with PCIE risers secured to that the GPUs plug directly into. This is a really nice design however it does require a bit more building material and by eliminating a shelf under the cards you allow for closer to complete 360 degree air flow. Now that we have our upper tier designed and assembled, we need to work on the lower tier which will house or motherboard and power supply components. As mentioned in the above sections, minimizing vibrations of these components helps prevent wear overtime as well as keep your sanity by eliminating the constant noise. In our design, we used 3 pieces of 1/8' thick aluminum to brace the the lower shelf: For the lower shelf itself, using a heavy metal, like stainless steel can help keep the shelf secure and free of vibration. We used a 1’8' thick piece of stainless steel sheet. You can secure the sheet to the frame with self tapping or machien screws, but the snug fit and weight alone was tight enough and vibration free as is. With our shelf installed, we need to create the ifrastucture to secure our Motherboard and supplies. A short piece of aluminum angle spaced out to the width of your PSU is a good choice to secure it in place. We used industrial strength adhesive to attach our angle, Last we used 1/4' CPU standoffs (female on both ends) as a base to hold our motherboard in place. Carefully mark your bottom shelf where the 4 screw holes for the standoffs will need to be drilled in the bottom shelf. From there simply drill the holes and attach the standoffs from the bottom with screws. This will allow you to install and secure your motherboard later on. Once you’ve secured everything in place, you are ready for cabling. 4.4 Cabling Now that everything is secured to the frame its time to begin installing our cabling. It is important to make sure all cabling is proper lengths, reaches without stretching and without too much slack which can cause tangles and make it difficult to troubleshoot later. Attach your cables, one at a time moving inside out. This well prevent your cables from crossing between each other. Use velcro to attached your cabling to the frame or any fasteners you have installed. Once you got all your cabling complete, you are ready for some testing. 4.5 Disassembly and testing Before you beggining your OS and software installation its important to do some testing and to disassemble your rig Making sure your rig POSTs and your bios is recognizing all your GPUs is an important step before finalizing your physical installation and moving your rig to its final destination. Once it POSTs and sees all your hardware, you are in a good spot to proceed forward. If it doesn’t you can easily troubleshoot the issue while everything is easy to get to. You will next want to know ahead of time how to take everything apart and reassemble it so that when you need to troubleshoot or make repairs down the road you’ve weeded out any issue that prevent from quickly swapping out components. This will also allow you to make any last minute customization or bells and whistels. 4.6 Customization With our rig ready to go into OS/software installation and the physical assembly completed and tested its time for any last minute customization, tweaks, bells, whistles, and branding. A $2 can of red spray paint for instance can go a long way to make your rack stand out a bit from the cold drab wire racks you’ll be sitting it in for the next year, For our build we gave all the aluminum and steel a coat of red so our frame matched the black and red theme of the AMD RX Vegas that the rig would power. OS & MINING SOFTWARE 5.1 Operating System 5.2 Drivers and firmware 5.3 Mining software 5.4 Tweaking and testing 5.1 Operating System Mining software can be run on multiple platforms and operating systems. Windows 7/8/10 are all supported by most mining software and pools. In addition several linux distobutions also have support including customize OS with the mining software built into it such as. While it is beyond the scope of this guide to cover the installation of all operating systems we will cover some of the considerations on choosing an operating system and best practices for installation. A windows installation or stand alone Linux install will allow for more flexibility then running say EthOS as you can install several different mining softwares and switch based on profitability and stability. However if you just plan to mine one coin, using something like EthOS is likely to be more stable. The profitability really will not fluctuate much and this is more of a user preference, although i do personally prefer a windows installation due to all the reporting and alerting i can do and find it easier to tweak drivers settings within windows OS. Prior to installing your operating system, its best to update the firmware of your BIOS, as doing this after a windows installation may cause some issues or you may have to re-do any settings or configurations. Once complete, you can move forward to the OS install. 5.2 Drivers & Firmware Once you’ve chosen and installed your operating system, it is important to update all of your drivers, firmware, and get the most up to date versions of software that support the hardware you are using. While most hard ware will work “out of the box” with OS drivers, up to date versions will be more stable and allow for more tweaking. In our build, going from the default VEGA drivers to the updated AMD mining drivers saw a 20% increase in hashrate and considerable reduction in power consumption. This drastically increase the profitability of our rig. You may want to steer clear of alpha/beta or non confirmed drivers and software unless they are the only ones that provide support for the hardware you are using. These pre-stable release versions can cause crashes and downtime for your rig. Once you have a working set of drivers, and a stable environment it is recommended to do a backup of all settings and/or do a full image backup of your hard drive. You dont want to be repeating this timely process again in the event of a system or hardware failure. 5.3 Mining software Once your rig is setup with an operating system and optimized with up to date drivers you are ready to install your mining software and start mining! There are several algorithms and coins to mine with GPUs as mentioned earlier in this guide and with that several different options for mining software. There are tons of great resources on installation and setup of mining software. The most popular/profitable are: Claymore dual miner (Ethereum + [coin]). Resource youtube, reddit, steemit, and right here in the Bitcoin Pub there are great resources for setting up and tweaking your mining software as well as choosing the most profitable option based on your hardware. Before you even begin purchasing your GPUs an mining hardware, install and test out the different mining software on your computer to see how they install and function. It is helpful to be familiar with them so that you hit the ground running when its time to install them on your rig. 5.4 Tweaking & Testing Once you have chosen and installed the software you are going to use it is CRITICAL that you test your software and HashRates with different settings. You can see DRASTIC changes in what your HashRate is in certain software based on your driver and bios settings. For example, simply changing the fan speed on your GPU can result in +/- 5 in hash rate. Take the time to do your due diligence. This is one area where holding your rig back from mining is profitable in the long run. Test your hash-rate/power consumption of your rig on every potential setting. When setting up our rig we literally adjusted every setting 1 unit at a time and retested the rate/power after each reconfiguration. A HashRate:PowerConsumption ratio so much better then what others had been seeing and reporting that people have called us out as liars until we confirmed with the screenshots and settings. We took a rig originally operating at 38 Mh/s| 355W per card to one hashing at 39.5 MH/s| 160W per card. We also found an alternative configuration of 43.5 Mh/s| 245 W per card. When you put that into perspective, that testing that took a week probably shaved a month off our ROI and increased our profitability by about 12-17% daily. Purchase an energy/power usage monitor. These are inexpensive and allow you to determine how much power your rig is using, how much your are spending daily/monthly on electricity and send power alerts if you reach certain thresholds or go offline. You can also use it to test the power consumption of your rig at different settings. We use one from. PROFITS & WALLET STORAGE 6.1 Taking Payouts 6.2 Crypto vs. Fiat 6.3 Storing Payouts 6.1 Taking Payouts Once your rig is up, stable,configured for your mining pool, and actively mining it is time to start thinking about what to do with your payouts. How and when you take your payouts will be a big factor in how much profit you make and how quickly you reach your ROI. Most mining software and pools will pay you out in the coin that you are mining. So for instance if you are mining ethereum, the pool will pay you out in ethereum. There are some pools and services however such as nice-hash which will pay you out in BitCoin or other currencies. So depending on how you plan to use your mined currency, you may want to consider one option vs. If you plan to convert all of your mined zCASH to alt coins, joining nicehash so you are paid out in BTC which can be easily traded with alt coins may be an attractive option for you. Conversely if you plan on keeping all of your mined zCASH as zCASH you are better off being paid out in zCASH. Another consideration is how often you take payouts. While it may seem attractive to get paid out as frequently as possible, the less often you take payouts the fewer transaction fees you will end up paying. Which over 12-24 months can add up. Additionally some mining pools/software will charge a higher fee for payouts less then a certain amount (i.e. Less then 0.1 ETH). You want to avoid these fees whenever you can. Monthly or quarterly payouts are recommended unless you are either really nervous about your mined coin living on the pool for that long or believe you can make more then the transaction fees trading your mining profits for alt coins. There is no right or wrong way to take payouts depending on your investment profitability and long term strategy on mining profits (holding them in the mined coin vs. But it is smart to calculate the costs and risks of taking more infrequent payouts with less fees vs. The alternatives. 6.2 Crypto vs. Fiat Prior to reaching your ROI, it may be intuitive to cash out all of your mining payouts/profits to US dollar/Fiat currency to pay back towards your ROI. Depending on your circumstances this may be the case. For instance if you bought some of your hardware on 6 or 12 month 0% credit offers and need to pay that back prior to getting hit with interest on the purchase, then applying that profit to Fiat/US dollar would make a lot of sense. Alternatively, the amount of profit you make could be drastically increased by keeping your mined profits in Crypto and earning compounded interest on that coin as the value of ethereum or other mined coins increases in time. Those who mine, and are involved in the crypto community typically project the market to increase over the next 12-24 months. If there isnt debt to be paid, keeping your mined profit in crypto is likely to increase your profits and help reach your ROI quicker. With any investment decision, doing your own research and factoring your own philosophies and risks is of the utmost importance. 6.3 Storing Payouts While you may already have a wallet for the coin you mine, it makes a lot of sense to create a separate wallet just for your mined coins. This will allow you to more easily tack how much coin you have mined and run any tools or reports regarding profit and projects to ROI. For instance, if you have an exsisting wallet with 10.43 Ethereum coins in it, having your mined payouts go to that same wallet may make it difficult to track how much Ethereum you mine over the long haul, especially if you cash out to trade some of that Ethereum. Resource There are several tools, apps, API integrations, and excel spreadsheets available right here in the bitcoin pub to help track your investments and profits. Redundancy is extremely important to any mining rig, and building in that redundancy to reduce downtime is crucial to avoid losses during hardware failure. Taking advantage of any free resources to help reduce ROI is crucial for anyone entering the GPU mining world. If you cans source PC components, building materials, software licensing or even run your rig somewhere with free power costs, your time to ROI will be drastically decreased. Lean on the community and The BitCoin pub for information and guidance. We have one of the most active and helpful communities right here in CryptoNation!

Thanks for the shout out. Yeah • Running on a MSI B250 PC MATE motherboard. EVGA supernova 650 Power Supply. No risers in the equation at the moment (But it happens with the risers in play too.) • One card is a PowerColor Radeon RX480 8Gb. The other is XFX RX480 8Gb. The cards look identiacal except one has a back plate and the other does not. • Currently Running Ubuntu 16.04 LTS, I’ve used EthOS as well. Driver is 1.2 AMD-APP • Mining software is ethminer No errors just reboots. I configured Ubuntu to restart mining on startup to keep things going. But like I said, sometimes after a reboot it will mine at a much lower rate for no apparent reason. If I could throw a limit into the command, it might fix it? Just curious if others see this happening as well? What is the draw on your power supply? Do you have meter to see how much you are using? You could potentially be seeing spikes beyond what your power supply can handle. Do you have the same issue with just 1 card? Or is it stable on 1 card? If it IS stable on 1 card is that true for both the XFX and the power color or is just stable for one of them? If it is stable for either card individually but no both, its most likely a power or heat thing. How hot are the cards running? Do you have anything to cool with? If you crank the air conditioning in the room do the crashes stop? The rig hashing different after a reboot isnt all that suprising. It could be either your card settings being reset after failure or a safety mechanism throttling the card. Does your mining software have any logs? Have you checked the ubuntu system logs? Step 1 should be determining if the problem happens with just 1 card or isolating the issue to 1 of the 2 cards. I have a Kill A Watt. Will that help me determine the draw on the PS? Or just the whole system? Maybe it’s the same. Yes, it runs 100% fine on just one card. Doesn’t matter which card either. I do have a separate personal barrel fan blowing down the cards. I see no temps on my rig sadly. On EthOS it did, and on ETHOS it ran the fans at nearly full tilt and yet it would still reboot. I’ll see if I can find some logs. Also, let me know if the Kill A Watt is really going to help here. I bought it to calculate energy use, but didn’t think it would help with troubleshooting. For the Kill-A-Watt its the same your power supply is basically the entire system. Thats what powers everything. What is it showing for power consumption? The fact that it runs fine on one card and it doesnt matter what card it is makes me pretty sure its a power or heat issue. Your 650W supply may power 1 card no issue but not both. Likewise 1 card may not produce enough heat to overheat but both cards might (especially if the rig doesnt have great air flow) The fans blowing full speed are an indication the cards are running hot fans not running full speed is actually a GOOD sign. The kill-a-watt should help us alot. It will tell us how much power the rig is using and if your running to close to your PSU’s limits. Also if you can see the power consumption as it reboots, that could tell us alot as well. If you have a 650W power supply thats using 600-650W continuous you are certain to see crashes. Id start with getting those power readouts and maybe jacking up the AC or setting up tons of large window type fans to try and cool the unit. Your bios/motherboard should have temp readings. If it doesnt you can get a seperate sensor. You can also try running your rig on windows, if anything ti will give you more t work with for troubleshooting. After day and a half of use of the recently launched cloud mining service we can continue sharing our experience from the service. The Income Calculator is showing shorter time for break in now, meaning that the profitability of the coins mined has increased and now we are getting more like 100-120 day than up to 180 days for return of investment (without reinvesting the earned coins) though this value still varies a lot constantly. We’ve started getting 68 KHS at first just to test the deposit of BTC, then have increased the purchased hashrate to 232 KHS and since then we’ve been reinvesting all of the mined coins back into KHS and we are already at 234 KHS, so two more purchased with the mined coins not bad at all for now. We are reinvesting only the mined coins, because we are still going to be testing the service for a while more before depositing more coins in it to purchase more KHS. Currently the exchange at has little over 73150 KHS (73 MHS) of hashrate for purchase at a price of 0.00144444 BTC per KHS. This is the hashrate being sold by the service from the available mining power (a second batch of 100000 KHS) that is on the market at the standard price. As soon as it gets sold the trades will go between users who have purchased some of this hashrate, so we can expect that there will be an increase in the price per KHS. With that said it is also going to be a good idea to purchase KHS now and then sell them at profit if you are not interested in mining on the long run. And while you wait for the price to get higher, something that can take a few days, you can still make some extra mining profit, so it seems as a win-win situation. We have also already contacted the support with a few minor issues that we’ve had. We’ve already explained that the service is still very new and in Beta and although things are running quite smoothly, there are still some small things to polish left, but again nothing serious. The support is already looking into these and hopefully they will fix them soon, so should you decide to try the service do report some problems you find and send in your suggestions to the Support – this will help everyone else using the service, not only you. We are going to share more of our experience using the service in the following days, but we would recommend you to try it out yourself as well by getting a few KHS as a test if you are interested in it now. May 26, 2017 - In this article we explain how to mine Bitcoin on Mac, and discuss whether that's a good idea. It's akin to digital cash, in that it allows users to remain (mostly) anonymous in their transactions. Bitcoin.org provides a comprehensive guide to securing your wallet, and we suggest you read it fully. HashFlare.io offers cryptocurrency cloud mining services on modern, high-efficiency equipment. Crypto Mining Blog. The Income Calculator is showing. So far our profit from mining with the purchased Scrypt cloud mining hashrate is about 0. Dec 26, 2017 Bitcoin Mining Roi Calculator 2017 With Genesis Mining! Cloud mining zcash cloud mining. Scrypt cloud mining. After our initial excitement about the cloud mining service where you can purchase scrypt KHS that will immediately start mining for you we can now share some more of our experience with the service. We have been using it already for almost half a day and it seems to be working very well so far, we’ve made a second BTC deposit and as soon as we got the third confirmation the Bitcoins were available for trading and purchasing KHS on the exchange. So we have increased our hashrate to 232 KHS for testing the service. Our initial 68 KHS were purchased with an exchange rate for 1 KHS of 0.00144390 BTC, but at the moment there is a slight decrease and you can purchase 1 KHS scrypt cloud mining hashrate for 0.00144360 BTC. The income mining calculator over at says that the return of investment will be something in between 90 and 180 days, the profitability of the mined altcoins probably changes often and that affects the earnings in each 10 minute session and thus the Break Even time is affected as well. However that will be true if you only purchase hashrate for mining on the long run, if you also start trading the hasrate on the exchange once there are more trades happening there as currently people are mostly buying as the service is new and there is big availability of KHS for sale. The chances are however the exchange rate will start to increase due to increase in the user interest and the price will probably start to grow. This gives you the chance to not only mine for profit, but also trade for some extra profit thus decreasing the ROI time. So far our profit from mining with the purchased Scrypt cloud mining hashrate is about 0.00072291 BTC for about half a day, though we started with just 68 KHS and then increased our hasrate to 232 KHS at a later time. The mined profit comes in steadily and is available to you every 10 minutes, so you can trade what you have mined for more KHS or withdraw it if you wish, though for now we are reinvesting the mined BTC into more hashrate. We are still very positive about this Scrypt cloud mining service as it really has a lot of potential, so you should give it a try if you are interested. One thing that we are missing at the moment however is the ability to deposit LTC and trade for KHS (as an extra to the available BTC support) with them and also to choose if you want to get your mined earnings in LTC or BTC, after all we are talking about Scrypt mining here, so LTC support is a must have feature and hopefully we are going to see it added soon. Is a new Scrypt-based Cloud Mining Service where you can purchase KHS and they will start mining alternative crypto currencies for you in the cloud right away. This service is really new and very similar to what is for Bitcoin cloud mining, however here you re purchasing Scrypt processing power and not SHA-256 like with CEX. It seems that the service is just a few days old and although there is some polishing that needs to be made it seems fully operational and working with thousands of KHS already available for purchase. Offers both cloud mining and exchange for trading KHS, just like you can do on with GHS and BTC. In this exchange you can purchase KHS for scrypt-based cloud mining in a private pool, and the earnings you get are also calculated in BTC. There is no detailed information yet or ability to control what alternative crypto currencies the pool mines for you, but it should mine based on profitability such as DOGE or LTC for example (in the future there should be an option for the user to choose specific coin to be mined). The current lowest exchange rate for a 1 KHS is 0.00144390 BTC and according to the calculator that the service provides for checking your profitability you should be able to get a return of investment for about 180 days or half a year if you purchase KHS at that price. The good thing about Scrypt mining is that there are not yet serious ASIC devices on the market and there are already a lot of alternative cryptos to mine, so longer term investment in Scrypt could mining seems more reasonable than in SHA-256 cloud mining power. We just started testing the cloud based Scrypt mining service by purchasing a few KHS to test with, so we’ll keep you updated to what is happening and how things are going. Hopefully we are seeing something that will give some good alternative options for people that want to have access to higher Scrypt hashrate without having to deal directly with the hardware themselves. After you transfer some BTC to the service (only 3 network confirmations are required), you can purchase some Scrypt cloud hashrate on the exchange and the KHS you purchase are credited to your account and should start earning mining rewards every 10 minutes shortly. We just got our first small mining reward in BTC as you can see on the screenshot above that we reinvested into KHS. So we advice you to give the service a try with some small amount at first to see for yourself how things will be going as we decided to do. Have in mind that the service is still in Beta, so there could be some hiccups at first, but these will probably be dealt with quickly.

Scrypt Cloud Mining Summary Another algorithm than SHA 256 is Scrypt. The hashing algorithm is for cryptocurrencies such as Litecoin and Dogecoin. SHA-256 is the hashing algorithm for cryptocurrencies for Bitcoin among other currencies. Individual miners like Scrypt because it requires a large amount of CPU power. However, most mining specialists agree that it’s only a matter of time before ASICs are widely available for Scrypt-based cryptocurrencies. Scrypt coins require less power than the power needed to generate coins based on an SHA-256 proof of work. While you could argue that Scrypt mining has been able to prevent some centralization in the mining network of certain cryptocurrencies, for now, there are still a few more improvements to the mining process that could take ASIC-resistance to the next level.

Bitcoin Calculator Usage All you need in order to make the Bitcoin Calculator display a result is to supply the speed of your mining hardware. In this simplest form the calculator will use the current Bitcoin difficulty, block value and USD/BTC rate for the calculations. However, the accuracy of the Bitcoin mining calculator improves the more honest information you supply. Interpreting the Bitcoin Calculator Values The mining results are based on multiple changing factors and are just valid for the given values, thus it's best practice to rely on the Bitcoin mining calculator for a short time frame only. While the Bitcoin difficulty has almost always risen after the expected validity of 14 days and thus might be somewhat forseeable, the Bitcoin exchange rate has proven to highly fluctuate, which might lead to a dramatically different outcome. Because of this dynamics we are only displaying results for at most one month. CoinWarz Bitcoin mining calculator and Bitcoin profit calculator.
