So in watching Bitcoinwisdom; it's apparent to me that the other exchanges are following the trading activity on MtGox.
I don't know if it's mostly bot trading or if there are actually people stupid enough to follow this trend...
In any case, it looks like a $200 spread is about all we will see. If Gox goes down to $1 then it looks like Stamp, BTC-e, and Huobi will slit their own throats...
This is a sad day indeed. The hearts of man have failed; a foul darkness spreads...
(I sold 1/3 of my BTC at $796 after the BitcoinSteve prediction just as a safe hedge... I'm still saddened by this series of events even when I stand to profit greatly from it.)
Well, yes its sad to see other exchanges following Gox but its particularly hard not to while being manipulated.... I say most of those large dumps on other exchanges are made by Mark and his friends:
