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.
We do not have full and accurate information about what is happening in El Salvador. Their economy has indeed improved but is it due to the impact of bitcoin adoption or is it due to the wise economic policies of the country's leaders? Or even if bitcoin does play some role in improving their economy, that is not enough to assert that bitcoin can play a significant role in improving the economy of a country or the world. Because besides El Salvador, the Central African Republic is another country that has accepted bitcoin as legal tender but as a result they have failed miserably.
So we can't just look at El Salvador and jump to the conclusion that bitcoin can play a role or has the potential to improve a country's economy .
