You can buy anything from anywhere in the world, withdraw money from anywhere in the world.
What more do you want? A government to announce "hey sheep, bitcoin is the new money"?
Bitcoin already accepted in most of the country, and there are more and more country adopting bitcoin nowadays, so I think bitcoin had become an international currency and we need initiative, dont wait but act, introduce to new user, it will help more people to accept bitcoin and there will be more shop accepting bitcoin so bitcoin will become more useful for life
Its not been legal by many countries but recently Japanese Government adopted bitcoin and announces it as legal one to use in their country. many corporate already started investing blockchain technology for the security concerns.
I hope we may get bitcoin adopted by the USA and UK governments soon. This technology turns the world transaction so simplified with the low cost.
