Could be Mark Karpeles trying to flashcrash btcusd on Gox to double or single digits. Not sure if he will succeed without cornering those who already have buy order at double or single digits.
Would anyone honestly sell? At this point what does it matter whether you have fiat or BTC trapped at Gox? It all seems like funny money to me. May as well load up buys and score some cheap coins that you may have a small chance of seeing.
