Taking profits at 100% gains from here is more destructive than useful. Exponentially reducing your reward from potential profits down here. Let the law of exponential returns work for you from these levels...

I would let the stock make its way back towards previous valuations (as there has been no dilution, just a large seller, that is why there is an arbitrage opportunity here) before selling.

Definitely hold onto it until it hits .03.
Once it breaks .005 it is moving straight up towards .01 and then .03 quickly after. Don't expect to get any shares though, the market makers played this one to perfection.
