Nobody said you should talk about the Euro and USD because of cryptocurrency. I have been making use of bitcoin and a few other altcoins for some years now and I have never seen a reason to hate on fiat, even though I love cryptocurrency a lot.

But, when people ask me what I think about fiat I usually tell them that fiat can stay, all of them can exist, as long as it doesn’t affect the other. And then I don’t see why you would complain about cryptocurrency, because the first word you’re always going to see or hear when you learn about cryptocurrency is that they are volatile. When you hear the word volatile you should know that there are some bad experiences that may follow since there are risks involved in it. It is left for you to know how to avoid those risks.
