If a person is imaptient, most likely that person would be a very aggressive gambler that won't stop until he wins big or loses everything. Compared to a person who is disciplined enough to know his limits and to discontinue if needed
Limiting your wager doesnt help you to win, it is just actually help you not to lose too much. I dont really see this as an important thing to consider. If you wanna gamble the smart way, dont gamble at all and just invest in the site. That is the smartest thing that could guarantee you profit in the long run if nothing happened
