Completely agree with you!
The World Cup or even the football championship on some continent is not interesting enough. I like club competitions of professional teams much more. It is more interesting to bet on them. And also you always have a club for which you always worry and are its fan. But of course, such bets are not always possible in large international casinos.
But, I think with the development of the gambling industry, this will also be common at the regional levels of competitions and football and cricket, tennis and other competitions for which bets are possible in large casinos.
True, our interest in this football club team has more options. But it's doesn't mean the national team has a small support base for gambling. Precisely for the national football team, the number of fans is much larger. That means each match will have a greater betting potential as well. Even those who don't like football will also bet when the world cup running.
