bitcoin is just money, and like any other moneyz it can not do magical things on its ow. people can use it as a tool to make more moneyz an make themselves richer by increasing their net worth but to expect bitcoin to end world's poverty is just absurd in my opinion!
Maybe it can, povert it lack of basic needs, especially food and clothings, you can get those 2 basic needs by the use of money, now if bitcoin can give you money and provides those 2 basic needa , then maybe it can solve world poverty, unless if every bitcoin holder choose to be greedy and not to share it to others then it will be a problem.
