There are some things, Bitcoin can do for poor people.
- Poor people are those, who pay the highest fees. With Bitcoin everybody pays the same(small) fees.
- A bank can freeze your account. If you don't have the money to pay a lawyer, there is not much you can do about it. Nobody can freeze your Bitocoin.
- A country can increase inflation by printing money. Most of the time the rich are better informed about it and they have a lot of their money in assets anyways. It's the poor, who get hit by that, not so with Bitcoin.
So, Bitcoin is already doing a lot for the poor, if they are able to use it and stop whining about, that it didn't make them rich.
