cryptocurrency is virtual money that has no physical expression. They are only in the form of computer code, encrypted data. At the same time, the imitation of the account is not controlled by the administrator: banks and terminals do not participate in operations with cryptocurrency, they are not regulated by the state. Anyone can get money, and this direction is called "mining". Mining involves the use of computer power to solve various problems on the formation of new blocks of the cryptocurrency network. Simply put, for overclocking the operating system, you can earn money. The mechanism is similar to investing money in shares, but instead of shares — the power of the computer. Therefore, we can not say that bitcoin is money out of thin air, then you need to work hard.
