Paper money will have a good image as is now, people cannot leave paper money because there is no any problem for the people to pay with paper money in their local stores etc.
I don't think the future is going to be good with paper money. People wants to have daily convenience and we can see it with bitcoin.
For sure bitcoin is going to replace paper money soon.
But we can't tell of when it is going to happen.
I feel that the paper money is a very good shape for a transaction tool, and I'm not sure bitcoin will replace it. in fact, paper money has been used since the first, and it is a tool change transactions of coins into paper money. they changed it because I think the coin is very difficult to use. Well, maybe in the future will only be a bitcoin digital currency, and will be shaped card like a credit card.
