How about not bitcoin, where a transaction doesn't consume 9 day's worth of an average family's energy budget?

Utility: a transaction costs $10, right? It's useless.

Security: Have you followed this? The actual recommendation is to print your private keys and stick them in a vault.

Trust: It's funny that, fundamentally, people started doubting the Federal Reserve when the gold standard was abolished, because suddenly "value of money is just fiction". Yet here they are, imbuing some far more ephemeral nothingness with the same sort of faith-based value.

Trust and security, maybe, but actual utility? That's far from clear. Cryptocurrencies have a rather extreme threat model and it's not clear at all that people who are not regime critics or criminals (I don't mean to disparage suppressed people here by lumping them in with criminals though) really benefit from that model.

Most people are quite happy with trust-based currencies which don't have the proof of work overhead. Cryptocurrencies have their utility, but not for the whole population.
