Hello my good friend, first I must apologize for taking you back to the ugly incidents that happened in the pass. Honestly, it can be very sad for anyone of us here on Steemit to have such an amount of SP in his/her wallet and at the end can't access his/her wallet using private key.

Reading through your comments actually brought out some tears in my eyes because I was touched right from the day I saw what Happened to your account 6years ago and now you can't have any of the key to the account aside the posting key.

Maybe its time for a more advanced recovery method as I have heard a few others have also lost their keys and can not access their account.

Yes will I strongly believe steemit team or witnesses are working on this aspects. Don't lost hope for one day you will get to access your fund back.

Have a nice day and stay safe.
