Bitcoin has not even begun to enter the mainstream. If it is going up like this now, its going to be off the charts when it finally does. Go long.
True, I am pretty sure that the people within the Government will begin to integrate Bitcoin into the common things that we use since Bitcoin is gaining a bunch of popularity among the civilians.
I just know that when the price drops a bunch the people that are relying on Bitcoin for them to survive will panic and there will be blood in the streets. We can only know when the time happens, since we cant tell ones future on our own.
Governments accept bitcoin not because they want to do that but because the banks have told them to do it. For their part, banks are forced to accept it as a form of payment and as a commodity, because the bitcoin has a big user base, that is, has network effect. The latter also determines the future of the coin.
