this is good idea to me, even though I think real money should be used for maket up or down, then hutong can withhold a small percentage from gain, like a casino. don't know if this legal or not though.
second this, mit does have several high hands also. but nobody is sharing... I am a fairly old ID at mit, I still go there everyday to other forums and also stock forum - for fun. but to learn stock trading, hutong is #1, period.
