Interesting. I always check the trading pool but during the past few days, people have been betting using the $25 or more pool, I guess these are long time players who started from small pool them move up to higher pools since they are now confident on their predictions.
Actually, it takes time to gather some confidence in yourself. Sometimes players show overconfidence when they get some news earlier than others. For example, when I heard the news that MT. Gox started to distribute the funds again, I thought Bitcoin would start to dump again and we would have another buying opportunity. I did not have enough balance to start a leverage trade at that time, but I am sure a person will open a position if they get early news about the market. I thought the market would move down. But look, the market is almost stable in the last couple of days. It's moving sideways. Glad to know that people started to place big bets!
