According to me the answer to this question is no, because only that person can use bitcoin who is educated and have knowledge and awareness regarding bitcoin. A person who is below poverty line can't afford internet and other equipments which are essential for using bitcoin so how we can say that bitcoin can end povert. y and moreover there are many greedy and selfish people in this world who are having a lot of money with them either because of bitcoin or and other means but still they will not help poor people.
Poverty is a very serious problem that the world is facing now. It needs a permanent solution rather than a temporary one. Bitcoin helped many of us here but it will not guarantee the answer of the world's biggest problem. I don't think that it will be a big help to those who don't have internet access which is the only way to access bitcoin. It may render some help but it will not solve it completely.
