Hey, from the economic perspective even Vitalik Buterin don't think that FIAT currency will be doomed. Not all people would like to have payouts in crypto.

Imagine world where you work 1 month then get your payout and the next day your payout is worth 10% less. Vitalik mentioned it as a strong argument, because not all peps will be into crypto. I think his point is worth to consider.
