The big question here is.

If you can make 15% ROI why not bankroll yourself and keep the full 15% rather than split it with others?

A consistent 15% compounding interest accrues a lot of value over time. There are studies which conclude that many successful and wealthy stock market traders only manage to earn 15% ROI per year on their investments. If you had a "magic script" which could mirror those types of metrics, why not keep it to yourself? And better yet, why announce it publicly where admins of sites like bustadice.com might become aware of it, and patch whatever advantage your script hopes to leverage?

Also I might announce something similar in the future. Although my plan will address some of the questions which your post raises and hopefully answer them in a way which might satisfy skepticism.
