I am interested in how long it will last, up to the point where it will fail. When doing a couple of times, it should provide back some statistics for me, where I can adjust further tactics on.
All right. I have been running this same script previously, or at least very similar to it. Stop at 1.13 and 4 or 5 time save. It indeed runs steadily... Until the rapetrain comes. I would recommend to not leave it running overnight even if you manage to run 3 hours for example without shit hitting the fan. Other than that it's just pure luck, as always. If you happen to stop the script always before that bad streak comes, then good for you. Most of the time you won't so the wall will come at some point unfortunately. Good luck!
Oh, and just for reference I lost 500k bits with this script at the end. Yeah, no hard feelings, I know it's gambling too and house indeed always wins. Inspired by your thread I just launched the script once again with 100k starting stack.
