OT: Blade, some very valid points.
You're really talking about one of the oldest, most basic, and most difficult trading decision everyone faces: when you have a losing position--hold and hope, sell/take the loss/move on, or average down.
Always tough, always depends on the person and his/her financial situation, trading philosophy.
Best of luck.
All that is needed to make a happy life is within yourself, in your way of thinking. -Marcus Aurelius
