Earlier today, I came accross this post from Myfe:
Is it possible to create a PGP Signature from any wallet address?
I appreciate the Kleopatra tutorial, but I don't use Kloepatra and I shouldn't have to use a new wallet simply to sign my wallet address...right?
Thanks.
I noticed that post too, but decided to respond
friendly instead of my initial sarcastic thought.

This would be a good address to sign a message to prove ownership. Since it holds 0.5
BTC, you can be pretty sure the address hasn't been sold with the account.
