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)
No difference at all. If it was possible to hack your Bitcoin message signature, it would also be possible to steal coins from the blockchain.

here.
Would that be OK?
Something like that works perfectly, yes. Do make sure that the post is / won't be edited; that's just one thing I'd try to make sure of. Or someone archive the page just in case there will be doubts in the future.
