Sure, there's cryptography in it. But you don't call a mail or http server "crypto". There's similar tech in git, we don't call it "crypto", we call it VCS.
Calling this "crypto" is just trying to add a mystic aura for stuff people don't understand, to further muddy the waters.
We have a word for this technology. It's not "crypto". It's blockchain.
Sure, it's your shorthand for "cryptocoin" or "cryptovalue". Which are again newspeak for blockchain, and we could argue that given its limits and usage of the last years they should be called crypto-investment, at best.
Which is still like ordering a pizza and forcefully referring to it only as "food". I want a pepperoni-food please.
Sorry for the rant, but it really feels like it's just a way to further embellish something with dubious values like the post points out
