You are obviously incapable compiling a simple P/L list so we have no idea how you managed to wasted all the BTC DMC had.

As of 1 July your reported that DMC assets are worth 2189.48 BTC,  shares outstanding 4066 and NAV 0.53848499754058 BTC
August 1 you reported the DMC to be valued at 1476.77 BTC, shares outstanding 2993 and NAV 0.493407951887738 BTC
You managed to lose 0.045077045652842 per share - 8.37% of NAV. No big deal.

As of September 1. you reported DMC assets at 1253.16 BTC, shares outstanding 20909 and NAV at 0.059933999713042 BTC!

Based on the numbers and reported holdings, you sold additional 17916 shares and managed to drop the share price by -0.433473952174696 BTC per share.
AMAZING!
Looks like you bought additional 43 shares of your biggest loser: BTCMC (31.3 BTC?) . BTW, why are you not reporting the dividends from BTCMC?  I estimate those to be about 14.25 BTC or so.

You also bought  40 shares of BTC-MINING (40 BTC?), that has probably earned DMC about 1.96 BTC in div. (or not?) So far, this has held the market value well.
Looks like you also bought 2080 shares of ASICMINER (208 BTC?) that has also held it value well.

Total spent on new purchases is 279.3? BTC - 14.25 in dividends in August. If you issued 17916 new shares to cover those trades (279.3-14.25)/17916=0,014794039 you received 0,014794039 per share? WTF?! This has to be wrong!
I must have made a mistake because I can not find trades in GLBSE.  Yes, someone traded DMC close to 0.02 and between 0.035 and 0.045 but this is only about 70 BTC in total on (August 15)

I almost forgot, you have liquidated the following DMC holdings in August:

Can you clear this up for me? Where did I make a mistake in those calculations? If I did not, where did the BTC go?
