You have been waiting 5 years, a few more months (max.) and you`ll see whats Happening. Things look really good now, my guess is we will get some results before end of the year. And if Centaurus becomes a real Company you probably dont want to sell anything at all.
I hear yeah, I know I felt like I got burned for not selling anything two years ago around the .30 range but I do believe this time is different.
I may start selling small positions on these higher volumes just to start getting my initial capital back; I would feel like I was selling every share for less than it was worth, but some realized gains would be nice while holding out for the future upside potential as well.
