Well, my country is small. When our crypto house opened (It works on 1%) they managed to make 1 million BGN (500 000 profit) in 3 months. And here from 20-30 people that I ask only 1 knows about bitcoin, and the only thing they know about it is that some people mine it
In our country, too, very little is known about bitcoin and treat this as a fraud. In more developed countries, the percentage of people who invest in the crypto currency is higher.
Some big investors and businessman were already in bitcoin since they see the growth they can get in bitcoin. It may not be popular yet but now that Japan introduces bitcoin ,other countries might find a way to use it. It can be consider a global crypto currency since every country and nation were free to use it as long they have internet and knowledge on it.
