So I ask what country do you think will recognize it as a currency?
Bitcoin is indeed a real currency. There are countries who are moving in positive direction of recognizing bitcoin as currency. For that matter Japan has already recognized bitcoin as currency. [1]
Russia is also trying to get hold of bitcoin. One big problem with the bitcoin as currency acceptance is bitcoins nature of decentralized. This lack of control is something bothering govts to act against bitcoin or trade water safely.

I doubt that Russia will adopt bitcoin. For me they are anti crypto-currency. And all the things that they have said for bitcoin and crypto is always changing. So I bet that they are really against any crypto for now.
Its legal tender in Japan. But its not their official currency. It is still Yen. And for that matter, I doubt that any country would make bitcoin their official currency. Its decentralized, volatile. The government or Central Banks of any country don't want any of that nature because its can really affect them financially. They want something that is stable and can be control.
