Football (the folks over the pond tend to call soccer

) is without doubt the most popular sport and the World Cup is obviously the most watched sporting event worldwide so the sportsbetting industry gets a lot of business during such international competitions. The public interest is so high that even people who don't usually bet or don't watch much sports have a punt or two just for fun. E-sports on the other hand is a niche business and its general public is mainly teenagers who play PC games whereas whole nations care about their national football teams. They are not exactly comparable in my opinion.
this will be one of the popular gambling sites in the future because the dilihar of enthusiastic people towards sports is so high then this will be a huge opportunity.
