I really think it is really becoming an international currency there are so many people all over the world that is using it,
And it doesn't matter where ever you are as long as you can access the internet you can send and receive bitcoin.
I think bitcoin has not become an international currency, although users have been covered in different countries but it has not made bitcoin in anywhere. You're not yet free to use bitcoin
Yes the Governments have not announced anything publicly yet but they have also not banned bitcoin yet and people who are earning and using bitcoins will continue to use bitcoins even if there is any interference from Government in future.
