This is just one of my favorite strategies but it is not the only strategy. Also, I agree that "Luck betting" is not fool proof system but it is much better method as compared to martingale system method.

If you check my previous thread,  I am a professional gamblers and I been winning consistently long term for the past few years. When I was beginner, I was a big fans of martingale strategy and based on my own personal experiences, martingale is a sure fail system in the long run. Out there there are many modified version of martingale system with some variation of betting style which is also worthless over long run.

In fact, all the betting strategy is worthless over long term. To guarantee a long term success in this gaming investment, combination of luck, skills, money management and good discipline is needed.
