The process of regulating cryptocurrencies by states will be long and ambiguous. Although the cryptocurrency has been in existence for the thirteenth year, a significant number of states still cannot develop a single line of conduct in relation to it, and therefore the legalization process is being delayed and carried out in a rather contradictory way. But in any case, the legalization and regulation of cryptocurrency, no matter how tough they are, is much better than the long-term uncertainty between the gray circulation of cryptocurrency in society and its ban.
