Sorry for the naïve question, but I'm just really curious. What would happen to Bitcoin price if, for example, Trump declared all cryptocurrencies forbidden?
Can Bitcoin survive because of decentralization or some other underlying tech concepts, or will it simply drop down into oblivion if the government decides to fight it for real?
Your question is really naive. If you pay close attention to the details of ICO projects, they often do not allow Americans to participate in their projects.
Potential projects to fraudulent projects, they don't want to involve Americans. They have anticipated difficulties with Mr. Trump so they did not want to cooperate with his country.
So the US government cannot have a big impact on our crypto market.
