They paid quite a few creditors in stock so maybe that explains a fair portion of the selling?
Also the original Cascade seed investors had just under half of their stock released from escrow so I'd guess some of them would have sold to be free carried on the remainder of their holdings (I certainly didn't though!!!).
But like you I'm surprised at the current price given the company is progressing. Perhaps not moving quick enough is some holders view?
