I think for bitcoin to be a real currency, government have to accept it first.
So I ask what country do you think will recognize it as a currency?
The first country that comes on my mind is Japan. Bitcoin is already established in this country and they are already implementing acceptance of bitcoin in purchases in the retailer stores.
Japan as well as Singapore is also on list and more chances are to japan because they are now securing huge benefits from the bitcoin as compared to any other region Japanese are the wise nation and they believe in development and development will come due to this revolutionary bitcoin, and if this will happen everyone will want to go there to earn such valuable coin.
