If the government has banned it, it means that if the people violate it, they will definitely be punished. Actually, we can still do activities here secretly, but to be safe, I would prefer to obey the government. I believe that money does not only come from Bitcoin.
Dollars roll in from all sorts of investments, but the gains? They're nowhere near as juicy as a successful crypto play. Gold's having a moment right now, sure, but long term, it's just not in BTC's league. People see those BTC profits, and they're gonna find a way to get in on that action, trust me.
Governments can throw out bans all they want, but they don't have the tools to really track or police this stuff. P2P trades? Those are happening under the radar, no problem.
