Obligatory not a finance person.

I meant it more like “not the best.” In that it’s clunky, energy intense, and widely unregulated. As far as I know, there are no better solutions which aren’t theoretical.

edit: But I guess there are plenty of small ways we trade value outside of a centralized currency. It’s just hard to put “great person who helps their friends move” on a credit report. But that’s less about currency and more about value as a concept.
