Okay it says I need to make my own PGP public key but doesn't explain how exactly so maybe I did that wrong idk? Out of curiosity of I use a hardware wallet like ledger nano s via electrum desktop app that is has not had PGP verification and worse case scenario no one can technically access my bitcoin that's on my hardware wallet. It'd simply be the pain in the ass of removing the software that's corrupted on the computer it was used on if I'm not mistaken?
electrum PGP Signature verification ensures that you have not downloaded electrum from an unknown source, which is often a scam, which means that once you install the application, connect the hardware wallet and click on the message signature button, they may be able to access all of your coins, modify the balance before signing, and show false data.
as we can know how this scam app works, but it will inevitably lead to you losing all or part of your balance, so try to verify the signature to ensure that you have downloaded the correct electrum.
