True. There are still rural places that cannot be reached by technology. Some governments leave it that way and dont want to intervene so that nature wont be destroyed. It is going to be a hard fight before bitcoin will be accepted or be known as a currency for everyone.

All the above this kind of places and people counts less than five percent world wide, we can leave off them for the statistics of moving bitcoins to be introduced to every part of this world.
