The popularity of crypto currency is determined by the requirements of the time.
In the century of ubiquitous dissemination of information technologies, universal means of payment that could be calculated in electronic space without binding to a certain country or institution are in great demand.
Such a tool became the crypto currency.
For the calculation of virtual money, only their number is used, so the crypto currency does not need a real expression.
Digital payment means are protected by a cryptographic code, which makes them more reliable in comparison with "real" money.
And because of the absolute decentralization of the emission of virtual coins, they can neither be counterfeited nor prohibited.
Another feature that promotes the popularization of cryptorays is complete anonymity. When carrying out transactions no one will receive any information about the payer or recipient, from all data only the electronic wallet number will be used.
And also the attractiveness of the crypto currency is that it can be obtained independently.
That is, the digital currency can be obtained almost "out of thin air".
But you can also earn money on buying and selling, as well as investing crypto currency .
At the same time, crypto money can be exchanged for traditional money, as a result of which they are able to bring quite tangible income.
