In the future far from now the paper money will disappear because everything would be digital and nothing will go with paper things anymore.
Its just a matter of time in my eyes.
I do believed that in the future paper money will disappear, and this is also written in the bible that paper money/money will no longer be useful at all in all countries.
Lol is it bible not write about bitcoin which will become popular currency and replace paper money in the future?
I think it happens because of natural processes. Something ancient will be replaced with a new one
