Of course there is but as I say on my post the risk is very low because of the kelly critirion. You can google it... In short words from the law of large numbers if you have a positive expected value of return which a casino has and you don't risk it all then it's nearly impossible to lose it all... but in the short term you can see a negative return(ex. the first week)... that's why payments are made once a month... Also I make much more than I give, this depends on the volume of players on the casino...so I hedge the posibility of a month being in the red so I continue pay investors....However if the volume of my casino goes down and the investors money doesn't make me any money then it becomes a loss for me so I will imediatelly return the extra money depending with the volume... That's why I have a limit... Read the whole post and if you have any more questions make a comment
