Re: Solving ECDLP with Kangaroos: Part 1 + 2 + RCKangaroo
I'm not going to create serious ready-to-use open-source solution for cracking really high ranges. You should do it by yourself if you want to crack #135 and get a lot of money 
But I'm going to update RCKangaroo to support old cards better (+higher speed) when I have time.
It would actually be great if 20xx GPUs could be supported! And if in addition a speed optimization for these 20xx and 30xx series is made great . Thank you But I'm going to update RCKangaroo to support old cards better (+higher speed) when I have time.
Yes, new version will support these cards and will be faster by at least 20-30% for these cards.
