I will not recommend him to take a loan because it is against the rules of gambling, not even about taking loan alone, but also about not using the amount you can not afford to lose. But I will also say that he should benefit from it himself, if selling it, only a fool will buy it.
Exactly taking loans for gambling purpose is way risky and not at all advised to anyone.Have seen many gamblers loose big amounts as they can't profit from it but have to repay the loan amount along with the interest so how can you repay it? So play with the amount of your own that you can loose.
