StupidityisContagious.com Sports betting systems online are a big seller and for good reason. It’s a fact that sports gamblers, as in gamblers in general, lose and lose big time. It seems that people who want to make money betting on sports are always on the look out for a sports betting system that will allow them to win. The problem is that I have yet to find a sports betting system that works. Most of these sports betting systems consist of chase betting, progressive betting, revenge betting or all the other forms of nonsense that doesn’t work yet continue to sell season after season.
