The best part of bitcoin is that it doesn't stop anyone from utilizing it, like internet or a radio. It has no limitations to its implementation.
I know you're positiveness and optimism on how to solve out poverty but I would say that Bitcoin wont really be enough.Why? due to resources on making people aware on its existence.For people who do have the idea or knowledge then it would be an advantage but mostly aren't capable. Those points above are indeed true but wont really be applied if the user itself wont able to utilize such feature.
