OP - you want to hold them. They're on the verge of mainstream. And I mean, REALLY MAINSTREAM. You will regret "cashing them out" in a few weeks/months. The interest is at an all time high. When "Big Money" moves in (they've already started), and values go up, and people are talking in mBTC (1000th of a Bitcoin because 1 BTC will be worth $1,000 and more).. you will be pulling your hair out in regret.
