For starters, over/under bets is a type of sports betting where bettors try to predict whether a combined number of score of both teams is over or under a predetermined value. It is observed that beginners tend to bet on the over side. Why? Because over means excitement.
It doesn't really matter if beginners bet on over instead of under. wether excitement or not, people will usually chose what they think will be the outcome. In betting no one is sure if what they chose is Best or not, that why they said betting or gambling is base on luck. Before a person chooses over instead of under, May be that he sees more opportunities in betting over instead of under. And morover it is easier to get an over than under but it depends on the type of over you chose. Let's say a person who chose over 1.5 and a person who chose over 3.5 are two different people. So it is likely possible for 1.5 to play than 3.5 so this over issues depends on the type of over. And moreso I don't see anything wrong if guys overly chose over instead of under since prediction is a random selection yet to play. Who knows what the outcome will be.
