good for you and i'm glad it is working out for you. I got in low and bought another lot in the 2s. Not worried as I am waiting for quite a while before I get out $10/share to break even and the rest i'm planning to ride.
However, look into the tax implications for yourself. The lot you sell, you may want to take the "profits" from the $2+/share lot. It may come up as a "loss" but that is better off for you on your taxes. Just a thought and not advice. I still recommend you speak to someone knowledgeable about this before you make any decisions.
