Fair enough, I understand. I might ask another one today for 30k, feel free to decline if it gives too much away. I've seen someone complaining about encrypted conversations and they are right, I benefited from public hints too and will from now on ask everything publicly. For transparency, my last question asked for the master fingerprint of one seed without the passphrase. Author declined as it would have been too easy to solve afterwards. Also, my previous encrypted question asked for the key origins (master fingerprints and derivation paths) of both cosigners. I'll keep that one private as it's strongly related to the 50k public keys question. The author is free to confirm or publish any of his replies.
