Most people won't give loans out to people who are suspected of going to gamble with it and quite rightly as you're almost certain to lose it, though I don't doubt some people take loans out under a different story and then gamble with it anyway.
I actually saw some that said they were going to gamble the loan and still received it, with collateral but still why would anyone loan money to a gambling addict
You just said with collateral. So what the problem if he want gamble ? He have collateral
