Some people are asking, "How can Bitcoin helps the world's economic?"
I think this is the right answer. Bitcoin has become a currency for a nation that is currently supporting all kinds of people. Bitcoin has become as an international currency at this point. Once again, technologies help the world to solve its problems. This can raise Bitcoin reputation among economic discussions. And also will give positive mood to Bitcoin markets.
To be a national currency, i think its almost impossible. Every country have their own regulation and their own currency. Maybe bitcoin can be used as international currency and i think its good. Bitcoin can traded on international market if many country accepting bitcoin as international currency beside US dollar
