Staking your bitcoin address in the forum is just like a kind of evidence or proofs that will help in your account recovery should it get hacked, or you lost access to your account. It will help to authenticate that you are the rightful owner of the account if it gets compromised in the future and just as Charle-Tim said, if you are staking your bitcoin address that means you will need to protect the security access to that wallet address such as the seed phrases and the private keys because that is what you will need to access that particular wallet address in the future if your account get hacked.
