Why is anyone still even trying to trade there, just move to one of the other 8 big ones.
Because most of them are currently down, running far behind, are showing prices way out of sync with other exchanges, or have a huge spread that blocks trading. btce and bitstamp look usable, but Bitstamp is at $70, Btce is at $80, and Mt. Gox is at $90. If you could get funds in and out of exchanges rapidly, you could make money on arbitrage.
