Gox's new trading engine and all of the upcoming exchanges (ex, Coinsetter) are completely unnecessary given the total volume on all current exchanges.
What a magnificent engine this is that a trader can't even put a protective stop loss, not to mention a trailing stop!
Gox will still maintain the lead [...]
unless someone who has experience in exchange / brokerage business finally sets up a quality exchange. If this happens Gox and others will die in 6 months.
