Bitcoin can potentially play a role in the economic growth of a country which can make a huge difference in the multifaceted progress of that country. If Bitcoin can be integrated with the way in which the traditional financial system of the country is growing, the global economic system can be radically changed.
It can surely play a role but I think it could have a noticeable impact mainly if very small countries decide to use it/promote it. We all know about the El Salvador case, the experiment is going pretty well but at the end of the day we're talking about a small third world country. Let's say Brazil try to do the same, do you think it could have the same impact? For the moment, I would say no, it won't. I wish Argentina would do something about, that would be interesting.
