Yeah, pulling the trigger is one thing. Knowing when to get out is another altogether... how much more can I get from the rest of this position? I feel like I can get 50% or more, for sure.... but then again, I don't want to get greedy and miss the boat while I'm up 25% or 30% either. 30% in two months would be a very nice gain on this one. It was $8 just a couple weeks ago, and it could easily be $8 again tomorrow, or next week. I've got it! Limit order at $13 for Friday the 13th. That way I can't miss the boat by not being online when GBTC spikes over 30% for a minute, and comes back down the next.
