You will always lose in gambling. In the short term or long term. If you are that good in gambling, then why don´t you do it yourself with your own cash?
Exactly. They are just here to gamble a sucker's money. If they lose they don't have any sort of liability. They would just probably say, sorry we lost. If they win big, they get paid if they lose big the investor will be the only one paying for the loss. So basically it's just a win situation for OP and not for the investors. Well, good luck with your scheme OP.
