No casino would survive with that kind of system. While they may attract a lot of borrowers, the question remains: can they ensure that they will receive the payment? We are discussing online casinos, where most of us gamble anonymously, so the risk for the operator is very high.
They cannot even accept giving such offer just to make sure that they satisfy their gamblers, that's but satisfaction but stupidity, because at the end you will not achieve satisfying the gamblers than disappointing yourself, if you're to start a new casino business, you will hardly see someone to lend you money to start an establishement and if you do, then you must have staked down your assets as qualateral instead, so why should you be a loan vendor to gambler who don't have money to gamble.
I am aware that some land-based casinos have lenders, but they would not easily lend money without collateral. This collateral serves as assurance since its value is higher than the loan, and the interest rates are typically high. These lenders are often referred to as loan sharks.
There are loan sharks and those people don't take it easy with them, they will take down their entire assets used as qualateral if they fail or to make repayment, even to this days, only few land base physical casinos engage doing his kind of offer by giving loan for gambling.
