Gambling using a loan money is a big NO. The thing about using loan money for gambling is when you lose, you lose twice. It just doubles your regret, doubles the guilt, and doubles the money you lost. In the worst case, you will be possibly get into debt and that is something that we want to avoid. When I'm engaging to gambling I always tell myself to only risk something what I can afford to lose, in this way I am always reminded to not exceed my preferred amount for gambling. So, only gamble using your free money, but if you do not have any, better not to engage at all.
That is good advice we should keep in mind so we don't get into debt trouble. And it's true that we shouldn't borrow money to gamble; if we don't have money, it's better not to gamble. But unfortunately, that doesn't apply to people who gamble out there because they are still trying to borrow from other people, even though some borrow from different people. And when they lose and are billed to pay their debts to many people, they will need clarification and can only run away every time they are billed. It is already a big problem for us where we must pay all the debts at once or we will be arrested for not paying them.
Having a loan just for the sake of gambling alone will just add some problems to you in the future and whether you like it or not, the reality about gambling is that you are always bound to lose even before you start gambling. Also, why would you add some extra problems to your life if you already know that there are no certainties that your bet will always go through in that given day. That's just a wishful thinking without weighing the situations carefully, sooner or later, don't be surprised if you are already digging your own grave.
