i dont know but similar selloff of tat.asicminer asset on bitfunder and havelock...
i suspect that asicminer is being devalued on purpose.. but what do i know?

my guess: TAT posted a reply from friedcat that hints at statements coming later (financials on July 23rd) - and says that Rockxie's statements (which mentioned July 10 for blades) had dates that were unofficial.

This thread is about BTC-TC. Apologies - I was wrong as pointed out by knybe, this is indeed a right thread to speculate (multiple places?) OFFICIAL UPDATE
