In case you don’t know, the mining is the process of bitcoin production, which do computers by solving complex mathematical tasks. In the beginning (sometime in 2009-2010) it was easy and fun to mine the BTC. Every person was able to engage in this profitable business even with not very powerful computer.
But the protocol and the very essence of the cryptocurrency production is constructed so that with each new born bitcoin the complexity of mining the next block increases. This led to the fact that at the moment you can profitably mine the BTC at alone if you purchased expensive equipment and you have the preferences of the electricity.
The process of mining uses your graphics card. Moreover, cards from Radeon are only suitable for this. But as we have mentioned above, producing of bitcoins at alone is not profitable. In addition, the use of a computer, even with a good graphics card, will not bring you great earnings.
Increasingly use ASICs – specially designed integrated circuits. They have not only the best of the computational speed, but also significantly lower the power consumption. And to further increase profit, the miners began to join together into pools, where dozens or even hundreds of miners gather their power together to mine more BTC. The profit is distributed proportionally, depending on the invested power of each participant of the pool.
