My last buy at .98. I have never sold a PTK share and won't until buyout . I too am hanging onto every share.
Sheldon is no dummy. He is putting more of his eggs in one basket, very good sign. He is obviously very confident for a reason.
If Sheldon agrees with the POET BOD monetization strategy, Sheldon's high ownership could help POET maximize shareholder value by voting against lowball offers. Seeing that POET is putting a Pinetree Exec on the BOD, and Pinetree was 1 of 2(?) allowed to buy into the last PP, I see this to be a likely case (that they are on the same page).
I see no reason why Sheldon would not want to get great returns like the rest of us. Then again, I have not proven this as fact on this immensely precise medium called a chat room/BB .... jokes. GLTA.
