Wow.. Wonder what stripykitteh makes of this..
I think everyone made the same of this: Greg didn't answer your questions because he doesn't care - he got his funds for playing already. I agree with you that some kind of supervision of what's going on in the fund would boost the confidence of investors greatly (there are now people willing to sell at a loss). Dr. got his funds just because he was articulate and sophisticated - but he doesn't need to prove anything to anyone as long as people in Bitcoinland are willing to buy that (risk of not knowing anything). And they were.
I think I am very much on the same page with you. I actually also think the fund can have profits (as long as it focuses on (intra-)day trading rather than actual investments). Unlike you, however, due to this lack of knowledge of what's going on in the fund, I decided to stay away for now.
