I don't see how bitcoin is helping people in Africa getting food or avoiding wars.
Yes, i also think of that many people dont know how to earn bitcoin and if they will be taught how it is not easy especially persons who never went to school. Poverty in every country is such a big thing and maybe yes bitcoin can be a big help to solve poverty, but for sure poverty will not end bitcoin cant do that, bitcoin can only lessen the people who are experiencing poverty. But then, if people who earn bitcoin will be generous and know how to share may bbe possible.
