I don't see how bitcoin can help to anyone, it's just currency in the end. I'm not economy expert, but I think digitization of currencies across the world can help in equal distribution, if everyone can be "it's own bank" then we can directly follow our founds and not give them piece of our earnings.
   They print money as much as they wish, for their own purposes. Maybe blockchain can make soms order in the world, and with that things can be much clearer. This monetary system is failed, richer getting more rich, and others are like slaves for them.
