A professional's response given that this is a penny stock and other options are not available, would be to sell at least 50% of their holdings and take the loss. Better than losing everything. Then if you turn out to be a hedge fund fraud pumping us with fear, or a legit retail investor assessing what we see and don't know, but fear might be happening given a reasonable assessment of today's dynamics, the option of buying back at a later 'safe' point is always there and the loss incurred on the sale will quickly be re-couped and more given their science, imo.
Money means different things to different people, but the above is what I believe a professional would do, if not totally liquidate,again with the option of buying back at a better time if such develops.
