Bitcoin should stay and will stay more than 100 years, there is nothing the government will do about it. The worse they will try to fight it but it will keep the privacy purpose it was been established to do. Government can not fight the bitcoin network, they do not have access to it, they can only let some people be afraid that they will sanction them at worse. This is where people will turn to the p2p and will continue in the decentralized mechanism.

The government will not try something so stupid about bitcoin, the reason is that many alternatives will be present in the future. The government's CBDC will be will be part of it.
