We are having a glimpse of the future.
In a few years fiat will not exist anymore, all national coins will be crypto-currencies: USD, EUR, JPY, GBP, etc…
The transactions per second of crypto-currencies are still preventing that from fully happening, but a huge progress has already been made and TPS keeps improving by the day.
Also, didn’t China ban ICOs, crypto exchanges and crypto-currencies? Interesting turn of events. Never say I shall not drink from this water, China!
