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?
You can't make an equivalent for Bitcoin with paper money, though. There's nothing that would work with something like that because you would either quickly run into governments looking for a blanket ban on whatever it would be that you're creating, or it would be subject to the whims of counterfeiters that would almost definitely be able to get around your security features if you don't develop the design around government-tier security. Then you also have no computing power that can make sure the transactions are being confirmed in the same way, among a ton of other things as well. A complete mess for the designer if it is supposed to go beyond what it has detailed.
