I know most people will favor certain Sport, because they know more about the players or the teams and information is power, when it comes to betting... but some Sport are 50/50 when it comes to the outcome of the match. (One lucky punch or kick can make a underdog a champion)
Regardless if it's a 50/50 chance of winning or not, it's still good to stick with the sports we have known.
We are also doing gambling here, therefore, expect the unexpected like an underdog might pull a win and upset the favorites. But keep in mind that it's not always the case where upset always happened. Of course, even with the support of a well-detailed analysis, it's not that it's a sure win already.
Sports betting is already tough, why add risks to consider betting on other sports that we don't know or are familiar with?
