Sportsbetting definitely is much better than just casino, and if I may add, there's a statistics that College Football has the best sportsbetting winning chance, I have read an article although I can't find it but it definitely says College Football although no reason was given. Also it's much better for you to do sportsbetting on the selected sports if you really like playing the sports yourself and not just because you want to bet on it and that you've done extensive research on it.
I partly disagree with you. When playing in a casino, interaction occurs between the player (and other players in particular) and the casino (it doesn’t matter the gaming machine or the croupier). That is the player directly participates in the game process. When betting on sports, this does not happen because the player is an extra. Nothing depends on the player except choosing who to bet on; I do not consider the ability to analyze information (previous matches, game form, etc.).
You used “college football” as an example. I believe that the lower the level of professionalism, the higher the chance of match-fixing.
It was precisely this kind of fraud that the topicstarter implied with his question: direct deception, match-fixing. Cappers are evil.
