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.
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.
Yep I use to bet on games I don't have much interest on but am sure before you place bet of such games like crickets and horse ride one need not much analysis just take the risk and move on.
