I do not think a gambler ultimately gamble only for money. It's the stress, fun, mix emotion he gets from it that counts. It's same as drug addiction if you are addicted to it. But there are people who have full control over it and they know how to control them from losing too much.
I will stop gambling if I won a lottery worth few millions on in casinos where I get the overall profits in few hundred bitcoins.

Trust me you will still gamble.
Don't you think those billionaires gamble? They gamble with high stakes!
