I wasted years of my life in crypto

I worked at a crypto exchange and after I came to the conclusion that 99% of crypto was scams and rugpulls, I sold all my crypto and vowed to have nothing to do with it. It's more of a religion than a financial instrument and absolutely nothing has shown to me that crypto is anything more than a speculative gamble, basically tulips with the religious promise of a better world. The number of employees that lost money on rugpulls while I was there, but "still believed in crypto" was staggering.

I've never understood crypto, however I'm long term Bitcoin fan and user, and don't consider it "crypto". I think Bitcoin is pretty much opposite what the typical crypto project is.

Ethereum seems useful as well. But that's about it

Tell me a single useful real world use case that Ethereum is being used in today, a decade after its creation

If I can solve that problem with another simpler, older technology it doesn’t count as useful. I don’t care if you can pay for things using ethereum when I can just use my credit card instead.
