Do you think its a good idea to have paper Cryptocurrency in circlelation too?
Like we have fiat currency digitally we also can have Fiat Currrency as paper.
I personally think its a good idea to have btc paper Currrency or metal coins too wich Will be accepted any shops!
Second point is that the dEvil is not the paper currency or any Kind of fiat currency the devil is the just the money printing out of thin air and lending this money out.
So nothing wrong with cash cash is not a devil!
I do not think it would be useful. For this to be valid, there must be a private key on the paper (maybe another system that can replace it, but it is not worth the effort for something small) and also it will be too risky. Stealing money will be very easy. Also, imagine that you buy something from the store and the price is 0.03561 BTC , how will seller give you the remaining money when you give 1 BTC.
