I'm here still, because if I sell now, I'll lose about 80% of my investment. What I would receive now is not worth selling for. I happen to believe that there is a reasonable chance in the future (a year or two) that I will be able to sell at least some of my holdings for a profit, and continue to hold some for a possible significant profit over the long term (playing with house money). I do not have any greater insight into these possibilities, but, why crystallize my loss now? I have mentally written the investment off, so it won't matter if I get nothing for it in the future.
Good luck with your other investments.
