Sports betting have always gotten a pretty negative reputation over the years. While it isn’t the fault of sports betting itself; it is usually because of the decisions that were made by some of the bettors. Now in the world of volleyball betting, NAIA often plays a bit part of this. NAIA stands for the National Association of Intercollegiate Athletics. They are usually the body that is responsible for the matches that colleges have against each other. College sport is something that is worth millions as most of the future big stars are recruited from. So the question would be: is betting on NAIA matches legal? Quick Answer: YES So what’s the catch? Generally, they don’t usually mind if you place a bet on matches.
