The short and only answer is no, bitcoin will not help to solve world poverty problem. Why? Because economical systems, regulations and laws are not the problem here. Humans are. People are so corrupt and flawed that they do not care about making this world a better place, they just care about themselves. That is why we will never have world without poverty, wars and terrorism. Bitcoin is nice tool but it is people who will be using it. That is the problem.
It can't solve poverty but rather it can help some unfortunate people to earn like jobless people. It can help them.financially. it can lessen maybe but to end poverty, I don't think so. As there are lots of poor people who can't access to.computer an internet.
