Aside their value their money, they have huge funds for them not to cling on gambling to win more.
For me this is how it is, of course a millionaire or rich person takes care of their money to the maximum, I have seen that some people are selfish with themselves, that is something that I do not see well either, however they take care of their money so much that they know that in casinos money is Easily lost and that hurts them a lot, in fact that is what all of us should learn, at least think a little more that way.
