I always think of the following situation when you want to buy something very expensive online with BTC instead of Fiat: If you only pay a transaction fee of $2 for a work of art worth  $ 50.000, the fee is practically zero. But if you pay two or three percent Fee for a work of art this value, then the prices can rise a lot >> $ 1000 or $1500  . ( Fiat ) and that's exactly why crypto and BTC will live on and succeed in the future.
