Who needs a system that be able to managed by everyone? Most people wants freedom when it comes to their own money. And by that it means if people know that there's an existing currency(bitcoin) that makes their money avoid being under surveillance. I am sure they will use it to have safetiness with their money.
It's not the point. We are talking about future of paper money here. Bitcoin can never be matched what paper money can do. And why such thinking of an idea of removing the paper money to give way for bitcoin? It's a dumb thing to think. Bitcoin is nothing without an internet so how can it deal for the usual transactions that paper money is involved??
Very rightly said, and the major point is how can we expect illiterate and poor people to start using bitcoin, they will only use that is easy and comfortable for them, and the answer is paper money.
And that's another one. We all know that internet can't hug all the places in the globe so it will have the same scenario when using bitcoin. There are lots of places that still don't have a quiet good development and still have that poor status even we count for many years.
