Crypto wont delete fiat from existence just like fiat didnt delete gold and silver.

To this day gold and silver are traded in the market at huge volumes and some countries still back up their fiat currency with gold.

Although, precious metals slowly started losing a lot of their uses in the mainstream market. And in the event that crypto goes mainstream and most people start using it, I expect the same to happen to fiat.

Its dumb to assume that fiat will completely fade away into obscurity, but it will for sure be losing a lot of dominance in favor of crypto.

And this reality might not be too far away from happening. We’re already seeing things like crypto credit cards from platforms like Binance, Coinbase and CoinOvy gaining a lot of popularity in the mainstream market. These crypto-to-fiat bridges will give crypto a lot of exposure and help make the transition to full in crypto payments much easier and smoother.
