Probably a good move, I got in around $2, can't belive I already made well over 100%, I've decided to let it all ride into the weekend, the thing that keeps me in is everyone states it is one of the most respected electonric exhanges in the market. It just had a huge 30 minute screwup. If it happened at Knight it could happen to any of the competitors. Someone is going to jump in and assist knight, it would be bad for the entire market and scare everyone if it went BK. Could be trading $5+ come Monday.
