Because of 2 reasons:
- Out of greediness.
- Hoping that their money will double or triple in a quick and easy way.
Those are not the only reasons why people gamble.
Personally, I spend a lot of time on gambling websites and online casinos just because it is entertaining and I have fun being there. I don't spend too much money though.
I spend few bucks daily, therefore, it doesn't matter if I win or lose. I just enjoy it.
Its appalling that so many people don't believe in gambling as a form of entertainment. The OP who mentioned 2 reason people gamble without adding entertainment definitely didn't carry out his research.
I have been gambling for years and I do it purely for entertainment. Those who play for fun will never have a reason to borrow but the greedy gamblers would go to any extent which is really very bad. I can't recall having any bad experience gambling because my intentions have been defined rightly. How can a player borrow money to play and expect to make profit when he is psychologically he would be disturbed knowing the risk involved. I am glad that stories like this are coming out because new gamblers would learn from it.
