I'm not so wealthy, of course, I'll not do gambling. The normal level of people gambles in order to gain money. If already I have enough money why I have to risk with this money? But there are rich people gambles just for the fun. They know even if lose money on gamble they have money again. But with the small amount you can gambling for fun.
sometimes those people who have a lot of money at some point have no idea where they have to spend their money , and with their unique and weird nature which feel thrilling more than having a sex or any other pleasure things , choose to gamble with that weird reasons.
it is rare happened indeed , but i do have seen some people with an attitude like that to treat gambling.
