We as users of the bitcoin surely hopes to replace dollar, but we also have to be realistic because the dollar is the strongest currency in the world that it took a long time to be able to replace the dollar. If President Trump confirms bitcoin, will certainly accelerate the process.
So according to you, 'The Highly Anticipated Anonymous & Decentralized Cryptocurrency' 's future depends upon a single person named 'Donald Trump'. Thats indeed funny. Government at max can contribute to Bitcoin's success by implementing it in government operations. Otherwise, since no objection is raised by Government till now about Bitcoin can assure that it is confirmed and in its free-rein!
