I think for bitcoin to be a real currency, government have to accept it first.
So I ask what country do you think will recognize it as a currency?
Japan would be my idea of this kind of thing, as they were more open for technology upgrades and innovations. But let see if theirs more country who have the same economic strategy that will recognized bitcoin and be part of it. As of now the only thing we can do is wait for bitcoin awareness be matured.
