I think it we will just minimize the use of it, fiat dollar and other fiats currencies, and enjoy more the use of crypto-currencies. It is because we live in a world where the government gives true peace for each country.
Well, if the government started using bitcoin or the technology, then that will be a great move. But for now, I think that will be far from happening.
I find it hard to believe this prediction because too few people know about Bitcoin and they use it as an investment tool. In addition the government does not want to use cryptocurrency instead of the dollar.
