There are a lot of players around the world. Not every games are favorite in all region. Some likes soccer, some maybe esports or some cricket or others.
Basketball is our national sport and we love boxing because the only 8-time world champion is our countryman which is Manny Pacquiao
Which one are you mostly placing your bets on? Besides, do you think gambler don't care which sport it is. I have seen gambler who don't have any fucking idea about cricket but he used to bet on cricket.
I love betting on Basketball and I bet regularly in our local basketball league and we have a betting called ending where we predict the last digits of the final score I won several times here bet is not that big and it's pure luck game that is why the last quarter is the most-watched because of this betting game.
