No one that bet with huge amount of money that has a strong heart if the person is losing. Gambling should be for those that can use little amount of money to gamble.
Gambling with some huge sum of money doesn't imply that such persons are strong hearted, in this aspect being able to maximize your losses and amidst all of the challenge gambling brings you still push forward that's the kind of people you can label as being strong hearted,cause nevertheless they still intend to keep their gambling habits going void of addiction and some other acts.
If indeed those who always gamble with a large amount of risk can be categorized as someone who is strong-hearted, then why in most cases do many of them get stressed when they lose? So there is something wrong here, most likely those who are irresponsible are gamblers who only think about their winnings and ignore the risk of losing, so that's what makes them dare to gamble with high risks. On the other hand, I think overall gambling with a large amount of risk can never be categorized as a good approach, because in fact everyone will never like something called defeat, and if there are those like that, then most likely they will be addicted.
