Not that bitcoin is not volatile (it sure as hell is), but you're picking the most stable currencies in the world and comparing them to a crypto asset that is younger than a kindergarden class. Try building the same graphs for 3rd or even 2nd world currencies and observe that they might have even worse volatility. I live in a country whose currencies devaluated in order of trillion times in 20th century if you count multiple "monetary reforms" and "denominations".
Sure, but nobody is pretending that the likes of the Venezuelan Bolivar show no more volatility than any of the world's [other] fiat currencies as they breathlessly hype its potential as a global reserve currency.
