Cryptocurrency is a digital means of payment. The main distinguishing features of cryptocurrencies from fiat money are decentralization, absence in physical form, and the absence of a single center of emission and control. Cryptocurrency can be tied to any asset (currency, precious metals, oil) or not. Cryptocurrencies are classified as high-risk assets. But with the right choice and favorable conditions, these instruments can increase in price by several hundred percent a year. They can become a driver for increasing investment capital. Even large investment companies and private investors allocate some of the capital for cryptocurrency trading.
