Today many countries accept bitcoin as a virtual currency, is it because bitcoin is so high that they think bitcoin can change the country's economy, or because the country has many bitcoin users already?
Legalizing bitcoin by many countries would be great yet improvement on the other hand will still depend on the people indeed. It is profitable but only few know how to. So it can not change one's country into a richer one unless people know what is discipline. Godbless bitcoin!
