Gambling is very fun activity especially with using money. However, if gambling is done continuously in my opinion it will be a bad habit. Simply done sometimes and not needed.
You can't gamble if you don't have money so it's no sense to gamble if you don't have. Its fun for those gamblers who use to gamble and have enough time for doing it.
We gamble as we want to take profit and have some fun at the same time.
