Churbz - You just answered a question that hasn't been asked yet, but will.

Somewhere in the near future when the stock is taking off it will be asked, "Who would be selling now?".

Given the time it has taken for things to develop, people need money to get on with the lives. I cashed out of one stock that I had with gains because I needed a car only to see it triple. I'm OK with that although it could have been a really nice car if I waited, but you can only wait so long.
