I don't think crypto is dead, I think fintech's usage of crypto is dead. They came in and ruined what could've been a unique and revolutionary idea by making prospective currencies into speculative assets. We might see it reemerge in 10 years with capitalists and right-libertarians staying as far away as possible because they (hopefully) learned their lesson. The point of a currency is as a medium to store and exchange value, but the initial spike in fiat value turning 12 bitcoins from $0.12 to $12000 and attracted investors, get rich schemers, and scam artists (but I repeat myself). It doesn't help that it was designed to have negative inflation, so people were incentivized to hoard and bet on the market's volatility, and there was no organization dedicated to keeping it stable like the Fed. Then alternatives to PoW like PoS came about which further incentivized hoarding and centralization (you lose stake if you spend, so don't spend).

What people miss out on with all the hate about crypto (though the culture around it deserves a lot) is that the technology itself is potentially incredibly useful. Bitcoin was a first crack at the "Byzantine General's Problem", essentially how to coordinate a totally trustless and decentralized p2p network. Tying it to money was an easy way to get an incentive structure, but for applications like FileCoin it could just as easily allow for abstracted tit-for-tat services (in their case, "you host my file and I'll host yours"). Stuff like NFTs have less obvious benefit, but the technology itself is a neutral tool that could see some legitimate use 20 years in the future like, say, a decentralized DNS system where you need a DHT mapping domains to IPNS hashes with some concept of ownership. Collectible monkeys are not and never were a legitimate use-case, at least not at that price point.
