I don't see government agencies banning bitcoin but instead, I think they will look for an opportunity where they are going to benefit from it. And also, there are countries like Philippines who actually support cryptocurrencies which is a good thing.
Governments globally just try to manage and control flow of money into crypto, in order to get as much taxes from crypto as possible as well as prevent potential money laundering. Blockchain is human society's future, not only bitcoin. By now, privacy coins are the most favorite targets of governments and law makers, not bitcoin, in reality.
