I agree with what some people here are saying. Only invest what you can afford to lose. If you have "over-invested", perhaps sell some shares back and only hold onto what you can afford to lose.

IMO, there is no need to be fearful of where this company is headed, but I do empathize with you. You also need to ask yourself from where your fears are derived. If you have already done your DD, you need to be prepared to wait for the next milestones (license, up-list, etc). I think many of us here get overly excited about the "what-ifs" that we forget to have realistic expectations and more importantly that our expectations should change with incoming information (HC backlog).

Keep your chin-up and play it smart. GLTA
