I do believe bitcoin has achieved those status of internation currency already, countries and a big part of the population hasnt recognized it yet but we are able to send any ammount between countries soo its just a question of time till bitcoin be accepted and recognized.
Technically speaking, bitcoin is an international currency but we need much much more recognition in order to conquer the world and achieve the place in mainstream financial methods of payment like paypal or wire transfer. The role of governments throughout the world is going to be a crucial in order to determine the future of bitcoin and other crypto currencies. Bitcoin can get legal status in one country and might get banned in another so its really interesting to see what happens in near future.
