Just crossed my mind today. Will it make sense if someone will create a paper money equivalent of bitcoin? And the coins will be the smallest unit of bitcoin, Satoshi? Like the currency today? I think it is okay if it became a globally accepted currency. And it will serve as a payment for everyday goods. What do you think?
We already have a paper money world! There are 190 different paper currencies to choose from.
Satoshi's breakthrough was how to create digital cash that couldn't be doublespent. It need to be on the net because that's the whole point of it.
