I don't think any country will create a fully public, P2P, blockchain-based cryptocurrency. Instead they will create currencies on blockchain platforms that are permissioned and that can be controlled.
Yes, I saw the news, and I heard that banks don't make cryptocurrency but only use blockchain , I also hope the central bank makes a good decision
Banks will never use cryptocurrency because it was a threat on their own business, they will lose their investors if people will focus on cryptocurrency since it was more profitable.
