There is no future for paper money and there is future for digital money like Bitcoin i think paper money is outdated system for acomomic system for this centuries and bitcoin is big chance for to change this aconomic system and i know it will change and we will only use bitcoin in the future.
I don't agree anyhow the banknotes it has a very strong foundation in real life because they were created by the government and of course there are legal regulations inside it.
Yeah paper money has backing and support from the Government and it will always there, and Government will never love to see that any digital currency replacing their traditional currency.
No country wants that, but it is bound to happen when you really think about the logic, we are the digital age and we will make most things go digital until we realize what a giant mistake that was and go back to like the stone age.
