In the next few years, most states will issue their national digitized central bank currencies, that is, their stablecoins. In general, this should play a positive role for the circulation of the currency of states, since the digitized currencies of central banks will be much faster, easier to use and cheaper to maintain.
There is no single opinion on how this will affect the popularity of cryptocurrency. Soon we will see the circulation of the Chinese digitalized yuan, then it will be possible to draw the first conclusions.
