Mining bitcoins is the process of computing hashes for which the system gives rewards in the form of a certain quantity of cryptocurrency. It is used from the inception of the network :BitCoin: and will exist long, as this provides it with performance.
In the early stages of development of the system to iterate through the hashes had enough CPU usage – CPUs, but with the increase in the number of participants the complexity of the calculations increased, and had to find a replacement. For mining btc miners began to use the video card. They show much better results when performing related tasks.
What is a BitCoin farm
To increase the amount of mined btc, people began to use multiple graphics cards connected to one motherboard. So basically bitcoin farm is almost a normal computer (at least, it consists of the same components), but is tuned for the specific task of bitcoin mining.
These devices include the following components:
- 1 and more than powerful enough graphics card;
- CPU (average performance);
- 4-16 GB RAM;
- hard drive, able to fit a database of the blockchain;
- the power supply that’s powerful enough to operate equipment.
While mining crypto-currencies, usually the GPUs are working at full capacity, causing them to emit a lot of heat. Therefore, they are placed at a distance of 5-7 cm from each other. To do this, use the riser extensions so that you can pull the map off the Board.
The efficiency of the mining farm depends on its power. One of the most affordable in 2017 card R9 380x (value – 10 thousand rubles). Power its graphics chip is enough to calculate the 500 million hashes per second.
If you expect earnings in local currency, the card brings 1.6 rubles per hour. This covers only the cost of electricity. If you put several of these cards, then essentially nothing will change – the farm will never pay off.
The same applies to the ASIC, which costs 100,000 R. Yes, for example, the model AntMiner S9 is more powerful than the R9 cards about 28 thousand times. But the consumption had approximately 360 kW.
Now to be a member of the network :BitCoin: it is very difficult. It is not enough even to have large budgets. To engage in mining btc can afford, perhaps the citizens of China with access to cheap electricity. This is confirmed by statistics: at the end of 2017 about 80% of all miners are concentrated in the PRC.
But mining cryptocurrency is still relevant. For example, R9 380x you can mine Monero or other altcoins.
But gradually the relevance of mining will decrease. This can be seen as personally looking at the performance indicators of production and listening to reputable members or developers of the respective systems. For example, the Creator of Ethereum in a recent interview with Forbes magazine reported that mining crypto-currencies will become almost meaningless after 2 years. In this area only the people/company that have large capacity and having access to cheap electricity.
