I do not think so that because of the existence of Bitcoin, the long term problem with regards to the world poverty can now be resolved because Bitcoin was not really a powerful thing that can make the poverty gone. If you were thinking that because it can provide money for income is now it can resolve the poverty, then it is not. Poverty is not just about money. It is also about the resources. What will you do with those money if in your place you do not even have those resources you need to satisfy your needs? It can just lessen the effect but cannot totall resolve it.
I don't think bitcoin will ever end the worldwide problem since a lot of people is not good in computer specially on those rural areas. Where the technologies is very limited but perhaps some of them know how to use some gadgets but is very little compared to urban areas, were a lot of beggars. Some of them are disabled person, some are homeless, etc., if the government could help those people i think it could help to lessen the people who are in poverty.
