I was told to stake an address that I have previously used as my bitcoin wallet address on my profile.
Do you own the private key of this address? You will have to sign a message from that for recovering your account in future and you will not be able to do that without its private key. I recommend you to sign a message including today's date like many other users have done in this thread.
Of course, I doubt the recovery team accept a message which has been signed from an address staked recently for recovering your account, unless they can verify that you have used this address on your profile before. I am not sure they can do this.
