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?
The market has grown enough to let it go into oblivion in a moment and the governments around the world will come up with regulation rather than taking the entire market underground. When the regulations are set and done we will see huge institutional investments from around the world and that will drive the market in the future.
Of course you are right, but not quite. The government can easily affect the market in their country simply by banning cryptocurrency. This is an obvious fact that must not be forgotten.
