Sports betting is not my thing anymore,but I can tell you that it's pretty natural for the majority of the people to choose the safest bets.It's pretty normal.Everyone wants to get some easy profits with low risks.The big profits come with a higher risk of losing and only a minority of gamblers have the balls to bet on it.
In sports betting,you don't bet against the majority,you just bet on what you think will happen and you stick to your bet.That's how I view sports betting.
