I know a couple of dudes who are really into NFT. It really does come across as a cult-like culture with odd terminology and a half-baked understanding of the technology behind it.
I'd say over 90% of people who bought cryptocurrencies have at best a half-baked understanding of the technology behind it.
OTOH, you could have no understanding of the tech inside microcomputers in the late 70's and still think it was a good investment, if you had an idea of its potential uses.
