money is just numbers and w/e. But when it hurts someone physically, that's totally unacceptable to me.
Everybody is hurt when they play the money game.
Even Zhou himself pretty much acknowledged that.
Bitcoinica did create a place for people to trade more efficiently and provide liquidity to the market. However, speculation is a zero-sum game (or negative-sum, strictly saying). I know there can be many justifications for Bitcoinica's value, but all of them are against my intuition and values.
Of course it's easy to take an ethical stance against something
after you've already profited from it.
