Hello Bitcoin Community Forum:
I used to pool mine Bitcoin several years ago and I used Bitcoin-qt as my wallet. A couple of years ago in 2017, I had transferred my coins from my Bitcoin-qt wallet to a crypto exchange vault.
Going back and logging into my old Pool account, I see I still have some crypto in my pool account that I can lower my threshold to send to my old wallet address. I could have changed my wallet address to send it to my crypto exchange vault but back when I setup my Pool account I chose to lock my wallet address so it could not be changed without my permission, now I can't change that old address without my Wallet Signature that is generated in Bitcoin-qt, and I don't have my old Bitcoin-qt software installed anymore and my old wallet backup file was deleted. Is there any way to restore my old wallet address by manually adding it to Bitcoin Core? If not, then I guess my Bitcoin Pool account is useless now.
Thanks for your help and suggestions.
Kind regards,
