If you see any of these systems, tips,ratings etc. ask one simple question.
"If it's as good as they say, why are they flogging it instead of just backing their own selections?".
The answer is, of course, they make far more money selling the system to gullible punters than by following a "foolproof" system. Steer clear of all of them - if it was any good it would not be on sale, I'll give you the tip.
