If you borrow money from someone, do not use it to trade or gambling.
This is the principle of loan. If surely we don't have a tangible or reasonable thing to do with money except for gambling or trading purpose, then is better we don't take it at all. Taken loan to gamble is the easiest way to get into a big Dept because such person will be struggling to pay off the loan and the interest, and will leave off spending only on loan which will jopadize such person future or plan. It's better not to take loan atol when a person don't have a source to pay back.
It will be like you can make money from it within a short period of time but the money will be lost within a short period of time instead.
That is how every gambler thinks, untill they find themselves losing it. At first it looks real like they'll double the amount untill reality pant down on them, by losing all.
