It is already a international currency as majority of people across the globe are using it, the only thing we need is that it should hit the mainstream to get more popular in future.
i think so. But some country not accept bitcoin, so what will we do to some country like that?
we can not do anything about their country, they have the right to refuse or accept Bitcoin as one of the payments in their country,
we can only hope that in the future Bitcoin can be one of the financial solutions in the future ..
