I am not sure when I will. I got in at $22.50, sold some at $70 and think this still has around 3 years to its peak and another 2-3 years after before competition really starts taking away from it. This, of course, barring any unforeseen disasters and whatnot.
I've heard all kinds of guesses on the where this is going. Conservatively, I feel this will at least go above $90. How much more, who knows?
