I tried this once when I am addicted years ago, but I manage to pull this off because of my confidence that i will win, however this is a dangerous move when applying to gambling. I advise you to do not attempt to do this again.
You are lucky enough to pull it and other can also do it but the problem is that they are not as lucky as you are when they borrow money to other people.
Many have said it including me that borrowing money to other people is like "double risk" because you got lost your money and at the same time, you will think a way on how you will repay your friend whom you borrowed money with and an additional interest on it. Although many are recommending not to do this kind of idea, it is not a policy or a rule that you must follow always. You can still borrow money as long as you can repay it even you lose the money you borrowed.
