i don't really believe in those brute-force methods, then you should have a dictionary that contains that combination, i don't think anyone in the world has anything like it, and if you want to get started with that then you have a super computer necessary, that is sometimes calculated, it takes decades to be able to crack something like this and by the time you have cracked it, the owner already has a new wallet that seems impossible to me
It is just luck. Everyday i give 15-20 minutes to try, so it's like lottery and the bonus is: it's free to join
However i tried the software with one of my empty wallet which i know the private key, i set the start point near of the private key and it successfully found it. It works and i like the thrill to try everyday.
