Just for the experience of it I think a group bet would be cool and splitting the winnings of course would be fun and I’m sure there would be celebrations and fun as a result of the winnings so that would be dope. If not winning it would suck for everyone but still probably end up with a night on the town so you really can’t go bad either way haha
if all your friends enjoy and have fun, betting with friends is not a problem. whatever the result is still feel the pleasure. but as OP said, it can be bad when there are one or two of your friends who start thinking about getting all the winnings and enjoying it alone, that would be bad. if it is a very close friend to you, maybe there will be a little risk. but if there are friends who are not so close there, then it can cause problems. money can affect a person's mind and ambition.
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.
Before friends would even consider putting money together to stake on a game together, that automatically means they know and trust themselves too well, so the scenario of one person running away with the winning ticket is unlikely to happen.
And then again, I totally see nothing wrong with a group of friends joining resources or money to stake on a game game, if they all have a mutual agreement on how to share the winning when it arrives, if they all contributed the same amount then it's only fair the profits are also splitter into equal halves too.
And again, we could have scenarios where not everyone in the group has an idea of gambling but is interested in putting in resources, which hopes of getting his own share if the game plays in their favour. This is one reason that could compell such a collaboration.
