Central banks are aware that cryptocurrency is now developing very fast and provides real new opportunities to quickly and cheaply transfer financial assets around the world. Of course, they will be primarily interested in the possibility of creating their own stable coins, and this process will require joint efforts and the exchange of information gained.

At the same time, this will mean the general popularization of decentralized cryptocurrency.
