I totally concur with your observation @op, this is exactly what people don't understand and they keep lying to themselves as Well as their friends and families, and this what I call ignorance.
I've seen a friend telling a friend to invest all his fiat money in crypto that soon, fiat will become useless as the only means of paying for goods and services will come through crypto, I laughed hard at this because this kind of people are into crypto but don't fully understand what crypto is all about.
Crypto and fiat are going to co-exist for a very very long time if not for ever, even after the whole world must have adopted crypto into our financial system.
