Bip39 is a BITCOIN problem and solution. So everything that he did could be done to a Bitcoin private key address. He educated me as to the amount of effort it would take if my seed words were found and maybe I obfuscated the order thinking I was clever..
This is good work and but no means is it advertising the shitcoin.
This was BIP39 exercise. If someone gets your private key they can watch all the addresses you use and one day make a fat transaction.
