I dont think that the bitcoin is able to help poor countrys just becuae i know for srue that lots of people will not even able to buy bticoins because they are
poor how will it help them.
He can, earning from a little but comparing with the value on their currency it's very worth for using bitcoin in poor countries because the bitcoin are standing into the shoulder of the USD, the strongly fiat in this time and that's why for using the bitcoin can helping the poor countries going outside from their problem.
