Risk Factor: Full disclosure, this is gambling. There is always a risk there. This method/script is basing its potential profits on the extremely low probability of busting. I have been running the script for 24 hours straight, and while I have been generating a profit, I know that there is a risk of busting completely. The seller has included an option to help counter this risk in his method.
Edit: added a disclaimer to the header of my post.
Any system that has a nonzero chance of busting is bound to fail sooner rather than later, resulting in you losing all your money. There is mathematically no chance of winning long term with such a system, even with zero house edge. As long as the chance of "busting" exists, it is mathematically a martingale system and any claims to the contrary (including "mitigating risks") are bullshit.

As has already been mentioned in this thread, the only way for gambling to make money is to have positive EV, and I can't see such a method being sold for anything less than multiple BTC in value.
