Gambling gives a sense of excitement to players. Specially when you are winning, you will always want more. But you don't notice you are losing your money.
when you get addicted to gambling you will have mental issues. Money is the root of evil if you will not use it properly.
This is the major reason why people find it hard to quit gambling because it gives them false hope of making them rich. In the beginning people do make some money but as soon as they get addicted, they start losing more than what they had earned with gambling. For majority gambling is a short cut for making money without any hard work. Everyone wants to have money in large amount without working hard and thats what gambling shows them.
