I do not think that it is possible, creating own money is illegal in every country. It would be different if Russian´s central bank create stable coin backed by Ruble, something like Digital Ruble, but do you think that it is possible that a private bank could create an alternative to the Ruble?
Sberbank, one of the largest state-owned banks in this country, wants to issue a stable coin in Russia. Therefore, here we are talking, most likely, about the creation of a national stable coin, that is, a digitized ruble. Most states are now working to create national stablecoins, which are much more profitable for states to use compared to paper money. Therefore, in Russia, in any case, they will create their own digitized ruble.
