This is too far-fetched. You still need a considerable amount of resources in order to get bitcoin, especially at its current pricing. Perhaps those citizens capable of allotting a percentage of their earnings to bitcoin or just savings in general would benefit from it, but the majority of these populations from developing economies have barely enough money to keep things going for themselves. Bitcoin is supposed to be safeguarding your wealth against inflation, and keeping your own money yourself instead of letting others do it for you, but it was never an answer to poverty, moreso a tool to cure such since it isn't meant and created to be one in the first place.
