Surprising to learn Cambodia had done it already. Pretty sure governments and banks are not going to create cryptocurrency that prices will be determined by the market, that's not how they want it.
The Chinese government had already said BTC can be treated as an investment which could change things eventually if they allow Chinese to invest in BTC and could they use the CBDC backed digital Yuan. So if they do, they are all going to harvest BTC from the market.
Of course, CBDCs will be similar to government non-cash forms of payment, only with better functional indicators. More specifically, it will be possible to say about them after their appearance.
