While it is entirely possible to be an expert on many different sports, the reality is that most people are not. You are almost more likely to make profits from betting on sports you really know about as opposed to those that you don’t, so it is a goof idea to limit the number of sports and/or games you bet on. For instance, if you are a huge football fan and know the ins and outs of the game very well, then it makes sense to focus on football betting. However, that is not to say you should never bet on any other sports, as you may find other attractive opportunities. But there is definitely an advantage to specializing in a small number of sports though.
