There is quite a lot of crypto that holds a very consistent value in a trustless, permission-less way and that people (including myself) use as a stable store of value. I suppose you might not be aware of them but it doesn't mean they don't exist. I'm not sure that volatility in layer 1 is a bad thing. You don't buy, for example, Ethereum expecting that it will be worth that same number of us dollars today that it is tomorrow. You buy it to use as computing resource on the ethereum network. If you want something that is stable against the US dollar (which itself pretty wildly volotile lately, thanks to the many Cheeto fingerprints of central bank currency manipulation) you might onstead buy DAI which you can be confident will be worth the number of US dollars you paid for it tomorrow. The ecosystem is maturing and there are valid, elegantly engineered solutions in the crypto space. Don't let the scams and speculation make you ignorant to the real work talented people are doing.
