For this and many other reasons, I think CBDCs will render stablecoins obsolete. There's no need to worry about this since crypto is all about decentralization. As long as decentralization wins, nothing else matters. Just my opinion
I guess my opinion will be not so popular on a bitcoin forum but I think it will be a positive change when CBDC'll replace pseudo stable coins, it will lower the risks for those who don't want to make own researches. It is easier to understand that CBDC is a fiat currency then to understand that a pseudo stable coins is not crypto and is less reliable then fiat currencies. CBDC will never replace bitcoin because centralized decisions always have pitfalls.
