I'm going to advise you put a VERY hard stop on betting or playing for actual money, unless you want to get the community shut down for illegal gambling, or get people in trouble who live in states or countries where it's not legal under any circumstances. Laws vary state to state here in the US especially, and even the states that are "legal" are tightly controlled.

I share a similar sentiment and even can add on to that. There is a potentially high risk of underage gambling this could open up as well, let alone the other legalities mentioned. 

Besides the legal aspect, there’s also the social aspect around money. Of course, gambling is a choice and a risk. Despite this, and the money this would theoretically involve being (relatively) a very small amount, people get very, very temperamental when real money is involved, far beyond any fake currency. Take a look at sports for example- players get threats to their life when someone’s parlay is ruined by their performance. Not to say this has that amount of stakes involved, but it can be bad drama waiting to happen.
