Crypto _has_ legit use cases (like you mentioned) and I hope it stays. But those use cases will never justify billions of dollars and this much resource, talent and energy poured to it (Usually to the benefit of a few, while costing clueless people their money)
Crypto could've been Bitcoin/Eth with a much smaller valuation and a healthy community and I'm sure most "anti crypto" people would've not been "anti crypto". It didn't have to be this big to have people against it. It could've been a technology we use like Venmo or IMAP. Something that solves some use cases.
