It is virtually impossible to individually profitably mine Bitcoin currently, you would need massive upfront costs to invest in the best mining processors and you also need to take electricity costs into account. Here’s an example of the costs currently associated with mining Bitcoin: My laptop, which is a gaming laptop that cost around GBP 1,000 has a hash rate of 3.8GH/s, even with free electricity this would only return GBP 0.10 per month pretty poor ROI. Of course there are miners which are built purely to mine cryptocurrencies and the best performing miners are currently priced at GBP 3,000 and have a hash rate of around 14 TH/s. With free electricity this would return you 400 pounds a month. To reach break even this will take 7.5 months. Assuming that the difficulty doesn’t increase (which it will) and there aren't more miners in this time frame (which there will be – via pool mining especially) then this could be profitable in the longer term. However, I will compare this analogy with actually investing in Bitcoin for the past 7.5 months. Bitcoin 7.5 months ago (15 March) was worth USD 1,242. Put the same investment of USD 3,000 into that you would get 2.415 BTC. At today's current prices this equates to USD 14,751. This is almost a 5x ROI over the same period that mining would take to break ev. 3,553,082,354,000,000,000 hashes per second would seem to indicate that many people think so (see ). The bitcoin network is a perfectly balanced set of participants, where nobody trusts anybody else but everybody is incentivized to play their part, verifying everything. Bitcoin miners provide the security that gives bitcoins value, and in return they are paid with a combination of newly issued currency and the network fees that people pay to use the bitcoin network. The bitcoin network adjusts how difficult it is to mine bitcoin every two weeks, and so far there are no indications of any shortage of miners! I would not purchase cryptocurrency if i were you. I would purchase power to generate/mine any cryptocurrency by yourself. Just see my table down there how much profit investments can make you. What is Bitcoin Cloud Mining and Bitcoin Lending? Cloud mining or cloud hashing enables users to purchase mining capacity that of hardware in data centres. So far there have only been 2 trusted companies around • -> Limited to 1 year per contract, mostly 150% monthly return. • There are also others around but only a very few are trusted like this one, below i added a picture from a different network. Some examples: • $500 Investment can bring about $229.26 per month. • $1,500 Investment can bring about $694.71 per month. • $5,000 Investment can bring about $2,292.56 per month. • $10,000 Investment can bring about $4,654.59 per month. • $15,000 Investment can bring about $6,947.14 per month. You may join at any time. Bitcoin cloud mining enables people to earn Bitcoins without bitcoin mining hardware, bitcoin mining software, electricity, bandwidth or other offline issues. Bitcoin cloud mining, sometimes called cloud hashing, enables users to buy the output of Bitcoin mining power from Bitcoin mining hardware placed in remote data centres. Then all Bitcoin mining is done remotely in the cloud. This enables the owners to not deal with any of the hassles usually encountered when mining bitcoins such as electricity, hosting issues, heat, installation or upkeep trouble. What are Bitcoin Cloud Mining Advantages? • No excess heat to deal with • Quiet because of no constantly humming fans • No electricity costs • No bitcoin mining equipment to sell when bitcoin mining is no longer profitable • No ventilation problems with hot equipment • No preordered bitcoin mining hardware that may not be delivered on time by bitcoin mining equipment suppliers What are Bitcoin Cloud Mining Disadvantages? • Unverifiable or otherwise shady Bitcoin cloud mining operations • No fun! If you like building your own Bitcoin hashing systems. • Lower profits – Bitcoin cloud mining services or mining company will have expenses • Bitcoin mining contracts may have the ability to cease operations or payouts in the contracts if the Bitcoin price is too low • Lack of possession of the Bitcoin mining hardware • Lack of ability to change the Bitcoin mining software Best Bitcoin Cloud Hashing Services Being listed in this section is NOT an endorsement of these services and is to serve merely as a Bitcoin cloud mining comparison. There have been a tremendous amount of Bitcoin cloud mining scams.: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s. Best Bitcoin Cloud Mining Contracts and Comparisons Bitcoin cloud mining contracts are usually sold for bitcoins on a per hash basis for a particular period of time and there are several factors that impact with the primary factor being the Bitcoin price. For example, Pay per GHash/s would be 0.0012 BTC / GHs for a 24 month contract. Contracts vary from hourly to multiple years. The major factor that is unknown to both parties is the Bitcoin network difficulty and it drastically determines the profitability of the bitcoin cloud hashing contracts. Bitcoin network difficulty is a measure of how difficult it is to find a hash below a given target. The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target. Bitcoin mining pools also have a pool-specific share difficulty setting a lower limit for shares. The Bitcoin network difficulty changes roughly every two weeks or 2,016 blocks. There are all types of cloud mining options for other forms of blockchain technology. Best Litecoin Cloud Mining Services and Comparisons There are limited options for Litecoin cloud mining contracts. If nothing on the list below meets your needs, you can buy Bitcoin cloud mining contracts (listed above) and simply convert the bitcoins you earn to litecoin. Hashflare offers scrypt mining contracts with a minimum purchase of 1 MH/s. Bitcoin Cloud Services (BCS) Review: Appears to have been a. Review: Based on they appear to have halted payouts. Cloud Mining is profitable. I do invest into cloud mining for about 1 1/2 years now. Mainly i use as my mining income, be sure to check them out. They generate me about $80/day and i’ve only invested $4,500. You won’t have to put in that much tho. Hashflare is giving you a one year contract with any investment you make, that means any money you invest will bring you profits for 1 year. Any money will do fine, here is some example math: They charge $1,50 for 10 GH/s in SHA-256: • Daily Return: $0.02 • Weekly Return: $0.16 • Monthly Return: $0.69 • Days to break even(earn back $1,50): 65 days. Some more examples: • $500 Investment can bring about $229.26 per month. • $1,500 Investment can bring about $694.71 per month. • $5,000 Investment can bring about $2,292.56 per month. • $10,000 Investment can bring about $4,654.59 per month. • $15,000 Investment can bring about $6,947.14 per month. The thing is You can still reinvest all of that money on hashflare. That will make you more money and extend the mining contract for another year for the specific invesment. If you invest for example $15,000 for 100TH/s (100,000 GH/s) then you could earn more then $4241,72 per week after the Week 10 and the initial investment according to the currect bitcoin price that got calculated. Affiliate Rewards Once you build trust into hashflare you can also recommend it to friends or family. I personaly have many friends who invested into hashflare. You can get an easy 10% commission for each purchase your referral makes. Be sure to check out their affiliate system. A few days ago a $400 charge hit my credit card and Amazon notified me that my was on its way. Essentially a Raspberry Pi connected with a custom -mining ASIC and a heatsink, the computer is one of the most interesting MVPs in modern memory. While you could easily recreate it yourself, the fact that 21 is building and selling these for a few hundred dollars is a testament to the future widespread adoption of BTC systems. Is it worth it? First, I doubt this 50 Gigahash per second machine will ever earn back the cost associated with buying and running it. Second, it’s very cool but I suspect that this isn’t quite the bitcoin droid we’re all looking for. That said, I would argue that it’s a fascinating proof of concept. The 21 computer. I’ve run something similar to it under my desk for about two years now and it’s been a fun if impoverishing experience. Heck, you can buy and heat your bedroom while you mine pennies a week. But you don’t mine bitcoins to for the riches, people say. You mine it to support the network. Latest Crunch Report. What this device is really designed to do is offer a test bed for bitcoin-based activity like sale of signed digital goods, the ability to rent out system time for bitcoin, and accept bitcoin on a commerce site. The core app is called 21 and it runs from the command line. Typing ’21 mine’ activates the bitcoin miner while other commands activate various features. You can also launch a server to perform basic bitcoin functions. For example, 21 offers a that uses Twilio to send payments. You can also sell using this server. • Founded 2007 • Overview Bitcoin is a form of digital currency, created and held electronically. However, it is a currency not controlled by a central source. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems. It is the first example of a growing category of money known as cryptocurrency. Bitcoin • Location • Categories,,, • Founders • Website • So why run this other than a testbed? In the words of one Reddit user, “There’s vision of a future where every phone will have a mining chip, and people out the goodness of their heart will pay for the mining chip and will mine at a loss for the greater good. A future where millions of people will buy the phone with the lower battery life, because they believe in bitcoin.” While this is a bit Utopian, it’s true: if millions of these mini miners powered the bitcoin network it would be a far more interesting world: bitcoin would move more quickly and with more surety, the rates would ideally stabilize, and the blockchain would be a force to be reckoned with in finance. In short, this is the Internet for money and, like early Internet servers, it seems quite limited right now – until, suddenly, someone builds the financial equivalent of Google Docs in the browser. The 21 bitcoin computer is a platform for experimentation. It is a clever hack, a nice MVP for the company, and a great way to get started in Bitcoin. You could quite easily recreate it on your own but without the specific software and server stack that they’ve made available I doubt you’d have the same out-of-the-box satisfaction. When I built my first miner it took a few days to figure out the pieces and software. To run this miner I simply typed “21 mine” and I was off and running into the cryptocurrency future. That, alone, might be worth $400.
