Just the other day when I tried to withdraw from a certain payment processor, which I've done 100s of times and is always instant, but it took 3 days because they were "validating it" (which makes no sense, it's a withdrawal to my own bank account), and I needed that money at that very moment, not 3 days later.
The only forms of money that I know for a certainty I can move at a moments notice are cash and crypto. Anything else I don't really own it.
The easiest way to withdraw my money was to ask the bank to convert my USD in to my local currency, and if I do that I lose close to 6% of my salary.
If I wanted to withdraw my money as USD, the only time I was allowed to do it is if I provided the bank with a valid flight ticket to prove I was going out of the country, and even then, I could only withdraw less than 40% of my monthly salary this way. (the % changes everytime the central bank wanted)
Every time I see people hating on crypto all I see is someone who either bet the farm on a get rich quick scheme or someone who comes from a very privileged background who haven't had a part of pey-check stolen by banks.
If you can't manage your own coins then btc is not for you, use fiat, trust the bankers[1][2] to hold your money.

See how a ridiculous argument it is?
So yes! IT IS the fault of fiat currencies.
