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".
