Well i guess its depends on the situation how the countries adopt the bitcoin as a national currency. It might be complicated i think, because not all people are using internet most specially the people around the provinces. How they could buy thier things if only bitcoin can accepted for payments.
I must say that this is the best thing if it ever happens because it will not promote the usage of crypto currencies in over country but will also help a lot in lifting the economy rate of our country and that the people living in this country will then be able to live far better life than they are living right now. Our government really need to take this kind of step to have a better future of those who are living here.
