I don't want to rub salt into the wounds but what made you invest such a significant amount into this stock? What research did you do to convince yourself that it was a good investment and what has changed? I the reasons that made you initially invest still stack up then hold if not cut your losses and you get to live another day.
For the record I would be in a very strong sell recommendation as the structure, strategy and potential of the company amount to pretty much zero based on my interpretation of the data. Others will have different opinions and I may very well be proven to be wrong.
