Yeah, you should sell as the stock is getting beat up. Pretty soon the company will have more cash then their market cap. Go figure. Perhaps they'll never see $.30 or $.90 again. The fact that the shares are low must mean it's junk. Sell already. Hit the ask. Bring it further down so the rest of us can buy up cheap shares once it's ready to rise with news.
They have no assets to sell, unless you count their clinical mAB patents, which could make big Pharma billions. MD ANDERSON partnered with them for no reason. Merck hired them for no reason either. Yeah, you should sell cuz you think it's worthless.
Me, I'm going to stick around and wait patiently for the company to progress because I know what I bought.
