Though you guys both have a good point here, but my concern is if the profit is to be shared equally, why not they all gamble personally on their respective casinos? Because whether the betting amount is been done collectively or individually, the profits is always likely to be the same. So if I was to be consulted, I would have suggested that they do the research and analyse on games to be played together, while they gamble individually, in other to avoid scenarios whereby someone will run away with the winning ticket.
I also agree with this. I think for the sake of the friendship staying intact and having no problems at all, all the friends should make their own bets with whatever amount they want and on whatever team they feel will win, and then they all sit together to watch the game. That would make it more fun because there wouldn't be any arguments or anything about the money or the profits or anything like that.
If I and my friends were to make bets together on a game, I would suggest this way because I feel this will make it better and more understandable. Sometimes even the closest friends can have problems when it comes to money matters, so it's better to keep financial things to yourself and only have fun together.
So I also think making separate bets on the same game and then watching the game together would make the experience more fun and exciting.
