I don't think that is really THE goal of cryptocurrency based on the things I learned so far from the very vision of Satoshi Nakamoto though anybody can have a program or a project using cryptocurrency for that certain goal but so far those type of projects never made a light in the market. Even if all Bitcoin will be distributed among all the poor, it will never make a big difference at all to bridge the gap between the rich and the poor as there is no simplistic solution to this global problem knowing how complex human nature is and the dire situations many people are into. Now, am interested to know what are your good ideas to address the poverty problem.
