As a casual observer I see the cryptocurrency space only seriously used by two groups of people: those who want to buy goods/services which are controlled in their or the seller's jurisdiction and so need a bit more anonymity than Paypal; and people who run ICO and more recently NFT swindles. I have yet to see a widespread other usage of cryptocurrency.
I'm not trying to hype you up, but I think that there's a lot of utility happening outside of your bubble. Some of that happens in countries you don't live in, other use cases appear between banking systems which remain opaque to you. That's not the same as "no utility".
