Just finishing my 8x RX 6900 XT build for some brute forcing some of those wallets

I have another 3x 3090 that is just hybrid and wordlist attacking
Thinking of setting a Hastopolis Server to try and attack one wallet for some period of time.
Welcome into the Hashtopolis club

You are working on some wallet hashes right now?
Yes, I am doing some tests to find what would be the "best" prince prepocessor strategy.
I think the PRINCE algo would work on brainwallets, but for small wallets You could also implement rules based on a standard password builds such like first Big letter->wordlist->date->special character
As of humans usually try to implement the special character at the end of their usually known and used password
I also think that most of those wallets could have russian or chinese characters its dificcult to find a good wordlist
Also this could help to build a good princeprocessor
