Crypto does have utility, but there's only room for one: bitcoin. Everything else is just a me-too derivative that can add nothing except the possibility of central control (like the "digital dollar"). The ability to instantly transmit the hardest asset known to man (harder than gold, in the sense of inflation resistance) does have utility, regardless of what critics say. It has downsides too: the ability to be lost…
Because if BTC is going to be my money for transactions, I actively do not want any of the speculation on its price. It’s not useful for normal transactions if the price can swing as much as 50-100% within a year — some quick searching says BTC started the year around $17k/BTC and is currently around $27k/BTC. BTC currently acts like both a currency and a speculative store of value, and only one of those is really useful if it’s supposed to be the future of money. Otherwise it’s just a more-volatile speculative bet than stocks or bonds or etc that people hope to eventually trade for USD.
