Cryptomancy, if it had a definition, might be something like this:
A magical art intended to interface with the blockchain.
I'm Cryptomagistus, an artist living in the Northeast of the USA, and I've been making cryptomancy drawings.
I will be sharing them soon here on Steem
Stay warm out there! Thanks for having a look.
