1. Zhou stated that he has a rule that he does not do any personal trading of bitcoin for something like 24-48 hours after seeing any privileged information in the database.
2. Nefario, where did you get 80k? I heard 43k. This is probably roughly on the scale of his profits, but like copumpkin said, I wouldn't be surprised if a backer is eating some of this loss.
3. There is no evidence that Zhou is doing any insider trading or betting against his customers, and he has repeatedly asserted that he does not and never will do this. Does he have the power to lie and steal from his customers? Of course, but until there is more evidence than just opportunity, I don't think its fair to be making accusations.
4. I don't think "The Manipulator(s)" is Zhou, but I am pretty sure whoever they are- they use Bitcoinica (leverage makes manipulation easier).
1. Zhou also stated that all biticoin for bitcoinica is kept in MtGox and that they didn't actually touch the coins. What happened there? 43K went missing.
2. 43K is the actual loss from the heist, and another 43K that he's giving back to his customers, he takes a double hit.
3. There is no evidence of anything, I'm just after reading that bitcoinica's not even incorporated(on reddit, but is that true?).
