Not much would change. Governments can create as many regulations as they want, but they can not enforce it when there is no way for them to control the rules of the protocol.
For me the price of the bitcoin will increase. But some of the rumors will say the different thing about the price of the bitcoin. It is growing more and more. It will be very high if the time will spend some more. If it will every happen then the bitcoin will be very high according to me. So it will be good and a lot of the people are waiting for it.
