When I go with my friend to watch soccer games, and we place a bet on who will pay the drinks. We get so excited and cheer for our favorite teams. We might even shout things like, "Go Mbappé, go brother...
!"
Of course, I’m not saying you should bet on every game before watching it... I'm just saying that human psychology is difficult to understand. Sometimes a 1$ bet or a drink can change the whole atmosphere...(as long as it's for entertainment)
How about you? Which gets your heart racing more: watching a soccer match with a bet on it, or enjoying the game without any bets?
I can't speak for everyone but I think it's psychological good if you bet on what you can afford to lose so you don't get carried away by too much emotion. If you bet on any game, your reaction should be normal and your interest the game should remain the same unless you bet on a huge amount that was going to hurt you.
Bet doesn't change my emotions during the match. If I bet or I don't bet, I react to how my teams played, I even move my body when there is some kind of action aspect like sliding to score the goal or heading to score the goal and many more. There was even a day that I nearly kicked my TV with my head when Victor Boniface scored brace for Bayern Leverkusen, I was in the mood as if it was me that has the game with me and that's how I react normally.
