I´ve been thinking, maybe the insider trading, or lack of buys, is because of something we tend to overlook, ie:

This is a small company, and no one is making much money. BC makes 65 K per year, and the others get less, or just stock options. These aren´t big corporate CEO´s making millions of bucks. I think Tyrkalo(not sure of the spelling) is selling just to pay his bills. The other insiders are counting on their stock options to make them money, if it hits, and don´t have extra to invest.
