The wallet I used here is not a desktop wallet, but a generated address from one of my mining accounts. It doesn't offer signing.
Sending a very small amount of coin back to it. If it helps I can send that to you to verify I control that address?
to me enough, if you prove that still control one of these address, even with sending some satoshi, but I do not think that will be enough to Theymos ,you not able recover account if hack occur again.
