Only remember an iceberg order at .65 on stockwatch which would indicate a position change, but it does look like a classic pump and dump..

Nov 25 saw a low of .33 so it looks like investors took the double at .66 and sold off. They do say sell on high upward volume and buy on high downward volume.

So it was either massive profit taking ,someone got some bad news, a breather before an upward move or a fake on close to get retailers to sell thinking the party is over.
