Could a mass push for CBDSc lead to restrictions on bitcoin or will btc remain a global alternative?
There's a possibility but killing BTC is a sense to shut it is very impossible as of the moment where bitcoin is as its peak. Even bitcoin at $1k price, it cannot be killed as there are lots supporting it. It will just revamp from its wake until more people joins. Banning bitcoin all over the world in every country is possible but knowing how US is very crypto-friendly this time, it will not happen very soon.
