For many reasons. I already made profit on the stock on the first irrational spike. I have kept the profit and rebought my initial investment on the way down. I now look at that as untouchable and my one high risk investment. In the chance (I am putting at 5-10%) it succeeds, I will have made hundreds of thousands of millions like some of you. But you can bet I will continue to ask hard questions as anyone should that is invested in a high risk stock. Especially one with no sales.
