I'm always looking for a way to get Bitcoins for free for my own personal profit. And at first glance this sounds like an interesting idea, with a small chance of success. And I'd like to think it could work, but knowing there are people out there even more unethical than me, especially foreigners, and I don't feel confident about this idea as a result.
Besides, I'm sure they have tried to crack them and failed, so what are my chances then for actual success? I think not good.
And if I watched this Hashcat youtube video correctly,
https://www.youtube.com/watch?v=d1Y6TPGzVn0 then I have to correctly guess the number of characters in the password to even begin? If I tell it to brute force a 9 character password and it is really an 8 character password, then it will never find the right answer?
I am trying to open a wallet.dat with Hashcat and a rig with 4 gtx1060 cards. Trying with eight numbers I have a time of about 3 hours .. for the answer !!!
