I'm sad to see it has got to this; we were all great supporters of a dream which has not flowered into the hopes we had. Two points I offer for your consideration:
If you were to invest the money you currently have in XPE in the stock market for the first time today, would you invest in in XPE, or some other promising stock? If an objective answer says you would have the best chance here, then stay in. If, on the other hand, it is with some other prospect, then why would you leave your last funds in XPE, believing your chances are better elsewhere? Your history here (like all of ours) means nothing, and so leaving your remaining money invested here makes no sense if you believe in something better. If you get out, you can always get back in if things improve. You loss is already real, and making it up somewhere else gives you something to write it off against.
At this time, it comes down to the wellbeing of you ... as a person. If the involvement here weighs you down and causes you worry and concern, make an effort to examine the above with a clear mind and see where it leads you.
If you find you believe there are better prospects elsewhere, then take what you have and put it somewhere better. You will be a lot happier having made that decision, because you have done something - something you believe is positive. Making no decision just adds to the feeling of despair and anger which surrounds all disillusioned stock-holders, and it generally continues until the bitter end, leaving the agony to fester forever.
Reassessing the situation and making a call - one way or the other - leaves you feeling a hell of a lot better. The feeling of impotence goes, because you have made the assessment, and the accompanying decision. You've retaken the power of control, rather than it being in somebody else's hands - somebody like Athan Lekkas.
And that independence is worth gold.
My best wishes to you, and all that are feeling the pain here.
