I think that other countries won't ban Bitcoin directly yet, at least not until they release their own CBDC projects, but they can slowly start to increase pressure on exchanges, wallets, developers, miners, etc.
It's obvious they want to have full surveillance and tracking in near future, so anything related with privacy is now under attack.
The only problem is that CBDC can not replace what bitcoin offers people and we and governments both know this so I really don't think they are going to start banning bitcoin after they released their govcoin. At least not all of them (maybe only the modern dictatorships aka democracies).
They already know they can't prevent people from using bitcoin but they still want to surveil. The solution was to force centralized services to implement KYC and report back. CBDCs fall under the same thing, they fill gap in the market that would help the government surveil. Right now what we have are stable shitcoins that are too shady and risky.
