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?Well you can't do anything for that, some country's are afraid of btc cause we all know that this kind of crypto currency is decentralized, they cannot control their people making all their transaction using bitcoin, so it would not be surprised if Bitcoin would take the place being international currency rather than Fiat money.
