DISCLAIMER: my nsec here is derived by a BIP39 passphrase, which is itself a BIP85 derivation from a ColdCard Q default entropy with low entropy BIP39 passphrase on top. I have no intention to bother rotate in the next werks, frankly, but over the years it's not impossible that somebody could get me, if I delay the rotation too much. If I start promoting kaspa, ethereum, BIP110, or coinbase promo codes, you know it's not me.
