It's a matter of, do you like being rich? And do you like to keep on being rich? If the answer is both yes, then avoid gambling at all times. Gambling can give you money SOMETIMES, but most of the time it takes them away. So better stay away from it, rich or not.
But many in these forum are saying that a rich person would not have a problem in betting on gambling even if he loses because they are filthy rich, Well I think that they are delusional money are not forever and that will surely be all be gone soon if you continue to pursue the risk involve in gambling.
