Option 3: Use your PGP key! It's more secure than any of the options above. Here is how I will do it.

This is overcomplicated and unnecessary for the case described by Poker Player.
I was going to ask, what is the difference in terms of security? Like 0,001% of being hacked if I use a signed message and 0,00000001% if I use PGP? Because in that case I would use the signed message, which seems to me more simple, although I find it quite interesting the different options. (I just used random numbers)
Let's do an experiment:
-----BEGIN BITCOIN SIGNED MESSAGE-----
Signed message will be revealed on 10/29/2022
-----BEGIN SIGNATURE-----
IIVa9HxfBRnnOFfks0sRBqlK5vd9tOzh6zgA6L6OFLfjCedQocGY6jxeg7tJLAnPKJrAk0RCf1rV6A6
ZSALY9tA=
-----END BITCOIN SIGNED MESSAGE-----
Address staked
here.
Would that be OK?
