If they could ban Bitcoin, I think they would have done it by now. If my government bans my investment on which I've been paying taxes, I expect full compensation for my damages.
Hiding BTC or the involvement in crypto in the same way would be far more difficult depending on what level of user one is. Good luck to the coinbase users, for example. The Govt cannot force anyone to stop using BTC individually, but they surely can make it worthless or own all of it through legislation if they want to.
Will they do it though? Not so sure. With crypto becoming one of the few islands of innovation and prosperity, why would they want to stop it?
