Honestly, I still believe that crypto could be used as legitimate alternative currency that can be private and also act as a universal currency in the age of the internet.
However as you said, most crypto is no longer that. The issue is that there is no actual control on how much any crypto is worth at any given time. Even stuff like art follows the same story because of the same reasons. Instead of using it like actual currency, it's being used as an investment to make more fiat money
