A few countries and central banks have been talking about digital currency, and most of them are carefully ignoring the term crypto. Fact is- digital currency is not the same as cryptocurrency. These countries/central banks are recognizing the benefits of the digital currency features of cryptocurrency, but they dont want any of the decentralized uncertainties that come with blockchain-based currencies.
Will countries or central banks create their own cryptocurrency?
If central banks create their own cryptocurrency and they still control the supply, i think it can not call cryptocurrency and its called digital money. Cryptocurrency should be not controlled by any authorities
