Do I call it greed or just lack of the right mentality. Gambling remains risky as always, so you shouldn't always be greedy. When you see a huge win, just take a leave and make use of the little you get from that round. Some gamblers have the wrong mindset and may want to make too much wins from just one game. Unfortunately they get their ticket or game cut and end up losing. If you are a person that have in the back of your mind that you want to make money from gambling then obviously you will end up losing too much. Just play and cash out when you got a lot from your round.
