No matter how rich I get, I do not think I would be risking throwing away $30 million.
I like to look at this from a different perspective. That's, I look at the percentage the gambling is staking or staked. It could be just an infinitesimal amount. If the $30 million was less than two percentage of their worth, then I don't think it was a great risk. Another's peanut could be someone else's avocado. It's an illustration but that equally applies to amount of cash as related individual gamblers. Any gambler who considers percentage won't overstake and that's reasonable.
