The "btcrecover" is not an option and merely a false hope to whoever has lost their bitcoins, in theory when explained it sounds good. But that's it, it just sounds good.
I have used other methods and done so successfully but if anyone here expects me to go ahead and post a proof of concept when there is 3 BTC being offered as a reward, you're sadly mistaken.
Can you tell me what sounds good when i initially explained btcrecover in this very thread.. Here is how i explained the OP's odds:
BTW: there is no magic trick for recovering a wallet.dat password. It's basically always brute-forcing, so the easyer your password was, or the more you know about your password, the higher the odds it can be recovered. If you picked a strong password and you have no clue as to what it might be (or contain), the odds of recovering a password are very, very, very small, even if you use a "professional" recovery service.
And i still stand by my words... I have used btcrecover on my own wallets in the past, but i had a relatively decent idear about what my password might have been... I clearly stated that if the OP has no clue, and he chose a relatively strong password, his odds are very, very, very small...
I'll explain it really easy for you.
Post the txt file that contains his password and the other 5,000,000 combination incorrect passwords, I'm sure this "btcrecover" you are referring to is some poorly coded brute forcing tool.
