i do think they hold some value for things like bank to bank, where each party is kiiiiind of untrusted and unrelated (not on a public chain - it’s just a private consensus between collaborating parties)

it also undeniably provides payment outside of standard card networks and the finance sector (people have been using crypto to buy drugs for decades now), so can be used to circumvent things like this mastercard/visa morality police garbage… i think in that, it’d be useful to have a strongish cryptocurrency somewhere at least to be able to provide uncensorable competition (the alternative to that being some global EU network that everyone accepted in the same manner)

but i think the value in blockchain in general is minimally about currency: that was just the first implementation… it’s a distributed, trustworthy log between untrusted individual entities. the benefits of that are honestly pretty niche, but i think it does solve some valuable problems… just most people should never even know that blockchain was involved
