Home advantage, beyond that I dont see any thing more. The major betting happens from the leagues and not the world cup. Even though someone might have become rich by betting on the winning teams in the past, it hardly matters when and how the games are being held. What happens that day on the field will need your luck to back you up. Anything is possible.
So better to study the teams separately during the world cup and bet accordingly.
Same. I prefer betting on leagues because they have more active watchers, viewers, and speculators. When it comes to the World Cup, I take my time to study the participating countries if I want to bet. However, I'm more familiar with leagues than World Cups.
In my opinion, the location of the game is not a critical factor, whether it's a league or World Cup match. The presence of cheering fans and the playing field itself are not significant advantages or disadvantages, as players get to practice on the field before the actual game.
Natural factors like weather conditions, such as rain or sunshine, can affect gameplay, but experienced players are accustomed to these variables. Ultimately, what happens on the field during the game is what truly matters.
For these reasons, I tend to bet more on leagues than World Cups where I know the teams and their capacity more.
