First paper bills

The first paper bills was created 1400 years ago in CHINA, this was the beginning of new economic,era and the payment habit's of the people were modified. Perhaps, the first paper bill were received with scepticism,as is the case today with digital payment methods.
Perhaps, in a few years the day will come the many people will find it hard to imagine a a world without Cryptocurrencies, like today we don't understand a world without paper bills.
