Bitcoin Miner Cloud
Bitcoin saw a surge in price between March 2015-2016, bringing back profitability to mining. Is it a good time to start mining again?
In the old days, gold needed to be dug out of the earth which required a lot of effort. Things have not changed much since then, someone still needs to make an effort to create ‘wealth’.
When it comes to cryptocurrencies, they need to be mined as well. This mining is computational and is done by specialised computers that solve very specific math problems. In the case of Bitcoin, only a finite number of them will ever exist – 21 million. So it is possible to solve these math problems, and receive Bitcoin in return till this number is reached.
Of course, there is always a catch, and the catch with mining is that the machines used to mine cryptocurrencies require a lot of electricity, and that is an expensive commodity.
What makes Mining Profitable
Mining profitability is a variable and depends largely on the type of mining software you own, the cost of electricity in your locale, the current price of the cryptocurrency you are mining and, of course, your own overheads.
We looked at some mining equipment on the market and compared how they stacked against each other in terms of price, performance and potential profitability.
- Mhash/s = millions hashes per second
- Mhash/J = millions hashes per joule
As is apparent from the table, there is mining hardware available for every level and budget. You could be a hobbyist or a full scale bitcoin farm owner and there is something available for you. It is however, important to consider parameters such as power consumption, price of equipment and hashrate before making a purchase.
Chinese companies control over 65% of Bitcoins mined
Cryptocurrencies like Bitcoin are designed to be difficult to mine with the passage of time as more and more units are mined. With increasing difficulty in mining and the need for better hardware, a lot of people can come together to mine. This collection of people is known as a mining pool.
A share is awarded to members of a pool who can show ‘valid proof of work’. Miners have a choice of many different mining pools. Usually, joining a smaller pool is the preferred approach so as to avoid concentration of hashing power.
Miners can use various approaches to mining:
- The Pay-per-Share (PPS) approach lets you get a fixed payout for each share that you solve. The payment is instant and is made from the existing resources. Total payouts using PPS are non-variable.
- Pay Per Last N Shares (PPLNS) approach adds an element of ‘luck’, which fluctuates between 5-30% on top of the payout you would have received had you used PPS.
- Slush approach, or Bitcoin Pooled Mining (BPM), is score-based. Older shares, receive lower weight than most recent shares. This has the advantage of reducing the chances of cheating in a round of mining.
- P2Pool, Eligius, Geometric and Double Geometric approaches are based on other existing approaches and are refinements.
As of the end of March 2016, these 3 Chinese companies control over 65% of Bitcoins mined. Ant Pool is owned by Bitmain Technologies Ltd which is headquartered in Beijing, China. F2Pool and BTCC also have their roots in China.
Cloud mining comes of age
Cloud mining is a relatively new concept and miners have far more choices in 2016 than ever before from among various cloud mining companies.
Edgar Bers, Customer Relations Manager at Hashflare.io, on the emergence of cloud mining says:
"Cloud mining is a relatively new thing but we see that more and more people are getting interested in such service. I believe that this service has a very high impact on current bitcoin community as it allows something which was previously only available to technologically easygoing people. The more people can get involved in cryptocurrency world, the higher are the chances that this will not be something to come and go, but something to stay for a long time. I think any bitcoin enthusiast would like to live up to the day when you can use cryptocurrencies in Walmart, LIDL or Rimi."
Cloud mining is basically a service that will allow you to pay for hashing power, which is hosted in data centres and sold in Gigahash/seconds (GH/s). Many cloud mining plans are available online but it is important to choose a reliable provider.
Alex Gromov, Media Buyer at Hashflare.io has this to say:
“When you compare cloud and private mining you will see that cloud mining has its unbeatable benefits, such as no power limitation. You would probably not get more than 6 kWt at your living place, while having a semi-professional “farm” is pretty risky due to high fire- and overall security reasons. In our case we use specialized datacenters which are equipped with everything necessary for convenient and risk-free mining.”
Cloud mining services to look into in 2016
We looked at some popular cloud mining companies and their offerings in 2016, the cost barrier to cloud mine is relatively cheap and users can start mining immediately. There are a number of cloud mining companies offering services. Genesis Mining was the world’s first large scale multi-algorithm based cloud mining service, which provides both bitcoin and altcoin mining solutions. Cldmine.com offers cloud mining services in bitcoin and other cryptocurrencies.
According to claims made on their website, $100 invested over a period of 1 year in bitcoin mining would fetch a return 252.77% or will turn into $ 252.77. Hashocean is another provider, which claims to have 392, 314 users as of the writing of this article and say they have paid out 137, 495 BTC since they started operations. Here is a comparison of some Bitcoin mining contracts according to cryptocompare.com.
