Bitcoin needs to gain broader acceptance by buyers and merchants to become a credible alternative to the incumbent banking system. What bitcoin does NOT need is to develop fancy speculation tools that most people do not care about.

As I said before margin trading increases liquidity at the cost of volatility. Real trade of real goods and services increases liquidity while reducing volatility

Good luck and best wishes zhoutong,your name will stay in bitcoin Metric forever

Do you sincerely believe the relative price stability we are experiencing since mid february (about the same time as the Tradehill shut down) has something to do with bitcoinica margin trading feature ?

If short selling has one major effect it is precisely that of reducing volatilty. Go and learn some basics from Khan Academy: http://www.youtube.com/watch?v=zAkMhEqWFF0

It's even entertaining. On the upside, I will enjoy the next (and b/c of stability long-overdue) bitcoin bubble, which will now definetely come back to us to sell my coins for $10 or more. The interest payment provided something really useful for all bitcoiners. In my wallet I receive no interest whatsoever and it can be hacked, too.

@ Tong Zhou - I think you are an honest person, please help as much as you can to get our bitcoins back from bitcoinica. Had 101 coins there!

After this is done, go to school and enjoy life. I doubt though you will come back with something more successful than bitcoinica. You already are famous. It isn't zero-sum, and people losing money in trading/gambling do at their own responsibilty. If one reason for you to leave is thinking they shouldn't lose money because it isn't good for society (i.e. all your customers as a whole), you should be aware that you are judging them and at the same time 'robbing' them of their liberty. So, this what a business is all about: You end up with money that isn't yours. Technically, this is what most/if not all businesses are and have to be -stealing. Morally, you could have used that money wisely to give back to the community. For things you consider important and things people urgently need. Perhaps this responsibilty would have been a bit much? :-)
