Fiat currency, hard cash, and some other stuff will become a thing of the past! I think we can start counting years before they totally disappear. The only place where you will be able to see cash will be a museum! 30 years ago we didn't have E-games word championships, crypto-currencies, the internet was not developed as it's now. We are moving forward and I think one of the next steps is having global internet money (that will be crypto)
and everything will be global and crypto!
