If the book was just entitled Betfair for Dummies, that would have been OK. However, suggesting that it will provide you with winning techniques, is misleading. The book suggests that "Trading" is a low-risk, method of gambling, which may be employed many times a day, in order to accumulate a healthy profit. Unfortunately, this method depends solely on your ability to predict changes in the betting market. Although the book provides examples of how to go about predicting changes, these examples are at best idealistic and hand-picked. In my experience, following the instructions in the book, my predictions are wrong as often as they are right. My net profit, therefore, is nothing.
If it is such a low-risk, guaranteed method of making money, then why aren't more people doing it?
