I always wonder why do people say "I am gambling for fun and not for the money".
Some people are saying that because they don't want to admit that deep down they want to win and earn a profit, so they could say:
'see? I played for fun yet still managed to win some money, isn't this amazing'?
Why do you use money to gamble for fun?
The higher the stake the bigger the fun, it is as simple as that. That is the reason people are doing dangerous things.
The adrenaline rush can be achieved in many different ways after all.
