Btc is widely used anywhere in the world. Not just in few countries but I think most countries who have access on internet. They have all the capabilities to transact thourgh btc and access btc. I searched for the most popular country and it says it's USA and to be honest I think it's true. Btc continuously arising in different countries right now. Some countries are showing interest and starting to adopt btc which is good for them.

Many countries are trying to introduce some measures to legalize Bitcoin, which helps turn electronic money into valuable assets in the public eye.
Some countries are interested in: South Africa, Slovenia, Estonia, Ghana ....

USA. And then China. I think these countries will be the fastest moving in the crypto-currency. And others only follow their successes.

I think it's Japan. If i'm right, I read some articles that tells Japan would be consider as the Bitcoin Capital in the world because their are really legalized and implementing btc in their country. In fact, other country are not yet recognize btc therefore most of their investors that interested to engage in bitcoin will do leave their country and go to Japan just to do investment. I think that the main reason why people still engaging and patronizing it, is just because of a huge of opportunity and benefits that the bitcoin can offer and give to them.
