if im not wrong i think bitcoin is already international crypto currency because all of us in different nations/country we still can have bitcoin and we can buy bitcoin as long as we have internet . so im being confused how come do you think that bitcoin is still not international currency. and also bitcoin is decentralized currency so it can considered as a internation currency.
You are correct that bitcoin is international currency but as of now it is not a world currency unlike USD. But this decentralized currency is much great to used in online transaction. Those people saying that bitcoin is not yet international currency they do not know how to used bitcoin internationally i think. But for us who already understand the uses of bitcoin we can say it is already international currency.
