Shares last as long as they are profitable for both sides.

About no pre-orders: Sorry, my mistake. The star description was mentioned in another thread.
With no pre-orders we mean that we are not asking you for the money to actually order the equipment as it often happens. As in you don't need to trust us to actually buy it. You get shares of already paid-for pre-orders from KnC who have already proven themselves as trustworthy. There are many Bitcoin businesses which raise money to actually pre-order something. With us, that middle step in non-existent.
