I think it would be able to end world poverty in some ways if and only if everyone are going to know it and use it as an instrument to escape poverty. There are a lot of things that should be dealt with if we really want bitcoin to help solve poverty globally. Each nation should work on the legalization of bitcoin on their place so that everyone will have the chance to know bitcoin. By this way also, we are helping every individual shape the world.
It can not end world poverty, think about those really poor countries like Africa do you think bitcoin is the solution? No, it is not. Do all part of this world have gadgets and internet? No, they do not have it. Like what I said before they would rather buy foods to live than to buy those things.
