The issuance of the number of different stablecoins has been growing tremendously in recent years. Since they are in fact basically digital fiat and at the same time a connecting link between fiat and cryptocurrency, which allows for more efficient use of cryptocurrency, this first indicates the growth in demand and popularity of cryptocurrencies. At the same time, the risk of various abuses by the stablecoin team or errors in the organization of their functioning is growing in this segment. Therefore, soon the states will regulate their circulation more strictly. In addition, the issuance of CBDC by states will also require this, because the digitized currencies of states will compete with the current private stablecoins.
