Why wasn't the territory just named Cryptography then ?
Seems to me that calling it crypto but with the description you have given just adds to the (unhelpful) conflation of 'cryptocurrencices' (dumb name) and cryptography.
I get the idea of 'trying to take a name back' but I don't think crypto was ever used much as an abbreviation for cryptography much anyway. (Although maybe I'm wrong and it was in some circles ?) I feel the use of the word mostly sprang into existence with the arrival of shitcoining 'crypto bros'.
