No, I'm going to auction it off
If you get the file and the money starts moving, I expect 9 BTC
Likely 100% of sold wallet.dat files are fake and rigged files that appear to control coins when in fact there are real private keys in those wallets. There are still some stupids that pay money for such files (do they?), so how do you want to convince someone that a) your wallet.dat is real and genuine and b) your clues to the wallet encryption secret are in fact usable and valid to have a chance to find it?
I would be surprised if someone offers you more than maybe 0.01
BTC for this gamble. LOL and on top you expect to get 9
BTC when a cracker succeeds. Just why would a cracker feel obligated to pay you that amount? Sign a contract, yeah, sure, good luck...
Always somewhat interesting with what ideas some come up. Do what you want if you're the only heir.
I don't get it, why e.g. you don't want to contact Dave from walletrecoveryservices. He's a professional, he has the gear and knowledge to brute-force wallet encryption secrets. He will guide you, he doesn't ask for your wallet.dat file usually, he will assist you to extract the little data portion of the encrypted encryption key needed to find the wallet's encryption secret (no private key is exposed or compromised by this little data). You don't have to pay anything upfront to Dave.
Our standard fee is 20% of the value of the wallet, only if we are successful. Zero otherwise
If your wallet is valued over $100K USD, then we offer a lower fee of 15% for an initial phase of tests.
(generally takes around a week).
Limited Wallet Information
Background
This page describes how to get limited Bitcoin-Core (or Litecoin / Dogecoin / etc.) Wallet Information for Wallet Recovery Services (so that we cannot steal your bitcoins even if the wallet password is found)
