I will sign a message from this address in case my account is hacked/lost.
you should sign it now so that the public knows you're the actual holder of the key
Why sign the message now? isn't most 'comfortable doing it when you need'? i have staked here only my address no signed message, it's worthless?
It is not necessary to sign a message now IMHO! If you stake your address here, it means you have control of it. But probably signing a message is formal way to stake the address, which is recognized by many members here. But it depends on you!
