Thanks for all your replies, i appreciate for it.

I still just wondering how many keys i can crack per second with Rtx4090?

There is a program which i tried before it's modified version of bitcrack which is synchronized with vanitygen which is working much faster than original bitcrack.

Did anyone tried it with Rtx4090?

Hello everyone!
I have a simple question about the power of gpu cards and the time to crack the puzzle 66

What is the actual cracking speed of Rtx 4090(Doesn't matter if bitcrack kangaroo or vanity) the faster one will be the better.

I want to calculate if i get 30x Rtx4090 How many days or months do i need to crack p66?
