Bitcoin is Internet money. It might help people who are unbanked or unbankable. If they have money and are unable to spend it through other rails, the permissionless nature of it can be very useful. Also because it may be safer to store a little data than a lot of banknotes or valuables, it might be helpful from a custody perspective (then again of your phone gets stolen you might really be in trouble).

If you dont have money at all, it wont be useful.
