Paper money will be banned entirely?
How long do you think that happens?
would it work?
What security and privacy risks would it raise?
And how would public and privately issued monies interact?
I don't think paper money will gone. Probably in other countries but not worldwide well, some even don't know how to use computer, mostly the elders. How can everyone will acquire money. It will really be difficult lots of adjustment will happened. Someone can get all your wealth by hacking your account without leaving any trace unlike in paper money. Well for me paper money is better for now. Maybe in the future when the grandparents are already from the millenials digital currency will be the all means of transactions.
