I choose fiat over crypto for purchases because of the inherent capacity of the bitcoin to become an asset. Once someone used bitcoins to pay for the cappuccino he ordered for. He will forever rue the day he decided to make that that transactions. Fiat is smart choice or decision.
Fiat is more spreaded and long before used of payment method while bitcoin is strongly a good investment and economies growth for us to enjoy it's big profit sharing attitude towards unwanted unnecessary movement.
