You say this right when your central banks went on a massive money printing spree, shot up inflation beyond their own baseline for years, and have created a frankenstenian K-shaped economy where everyone who is not in the top 10-20% is getting actively poorer
It doesn't take a lot to figure out that hard currencies with some supply cap tend to hold value better. BTC might not be it - it might be gold or silver - but you really can't ignore the inflation issues inherent in fiat currencies anymore.
Deflationary "currencies" like crypto are significantly worse (why spend when you can HODL). Regular crypto "currencies" will have the exact same effects.
