There is indeed some truth in this because as everyone understands (even if they deny it on the surface, but inside they know for sure that this is so) that without relying on the same "fiat money", any cryptocurrency is just useless numbers that cost less than nothing.
everyone wants wealth in fiat money - dollars, euros - from cryptocurrencies, but they do not want to use cryptocurrencies as a measure of price in itself. no one wants to go to a restaurant and pay a conditional 0.2eth for dinner - they want to go to a restaurant and pay $ 100 for dinner, but through eth conversion.
People themselves have come up with a gasket between themselves and fiat money and believe that this is the real future and independence - but they do not want to understand that such actions simply kill what the cryptocurrency really is. and at the same time, they do not forget to say and write everywhere that fiat money is evil, that banks are evil, that the state that prints money is also evil.
And it's both very funny and very sad. Tragicomedy as it is.
