I guess many will choose to use Bitcoin openly and freely than living in fear. No one wants to be prosecuted by the government. Not all countries will reject Bitcoin. Especially with the taxation benefits it brings. Mainstream governments will only increase regulations to "keep everything under control". It will be legal to use BTC, but with restrictions.
CBDCs will only make central banks bigger and stronger than ever. It should only be a matter of time before we witness a "global reset". Perhaps, the economy will be restored after such an event? Only time will tell. As long as people are able to obtain true financial freedom, nothing else matters.
Actually i think it could make central banks smaller, depending what do you mean by bigger and stronger. They can be in fact a direct competition against the current banking system and would challenge visa and swift. Just the infrastructure that wouldn't be needed anymore would be huge, starting from paper money becoming irrelevant.
The main purpose of cbdc among with control against money laundering, is saving money for both banks and users by automation and getting rid of unneeded infra.
Standardisation, 24/7 uptime, smaller fees and simplicity of it will definitely cause near instant adoption, but people that it will put out of work and people benefiting from the current system will lobby their heart out for anything other systems than cbdc, like switft and paper money, so they will co-exist for a while at least, but with way smaller capacity. And that will result to the fact that surveillance on old system increases exponentially, and it will become harder to profit from, at least with illegal ways
