Andrew Haldane said one solution would be for the Bank of England to issue a state-backed digital currency based on bitcoin. Supporting this initiative would be a negative interest rate levied on paper currency relative to the digital currency, with these measures do you think there is more possibilities that sometime:
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 think paper money will get replaced by bitcoins and if you collected bitcoins now it is a good advantage for you.
Yes paper money will be replaced by bitcoin but very slowly as paper money is a part of human life style for many centuries. Already this work has been initiated by credit cards in the form of plastic money. When bitcoin finds more option for physical usage then that's the end of paper money.
