I doubt about this maybe it can help them for a part but on the other hand I do not know how we can really help them with using the bitcoin because its stays global and the fact is that the economy in such countries stays the same.
You do not need to wonder how bitcoin help poor countries, because bitcoin will help the country's economy, I think people just need to use bitcoin
That's not fair. Bitcoin as a digital currency doesn't have any dependence over the world economy. For this reason even when users continue to use bitcoin, it won't adds up to the countries economy. Because more and more were using to get out of taxation and save more. On this the governments income is getting blocked. The educated people from poor countries might benefit as its happening in Brazil.
