After stumbling upon a conversation on Facebook on how to copyright a book for cheap, I researched "Poor Man's Copyright" and realized that you basically are using a notarization service to prove the existence of your document at a certain moment.
This is basically what you do when you *Notarize* on the Bitcoin (or Ethereum) blockchain.
To figure out if there's demand for it I'm offering free notarizations in exchange for a quick call to figure out if there's demand for the business
