I think fiat is something that should and would exist alongside Crypto. We've been talking and waiting for a major adoption wave, but IMO, crypto will attain relative stability when it has come to a sort of 'understanding' with fiat. Both will become tenders for transactions in almost equal measures. But for now, we still have to settle for making the most of Crypto and the use cases that are on the rise each day. Like only recently, I paid for my meal with Tapcoin, an alt, and it was cool to spend Crypto on basic things as food.
