Bitcoin is very easy to access by anyone, anywhere and anytime as long as there is internet. Maybe that's one very powerful reason, why bitcoin should be used by everyone. And bitcoin will be the future of money for the world.
But what about that people who haven't got asset to internet? Firstly you can thing that all around the world have internet access, but it isn't right...
How can you use it as money and, for example, buy milk in market if fees for $ 1 transaction will be too high?
