I was in early also and did well. Impossible to not take profits on a run like this. Once it starts to trade heavily it becomes much more of a trading play to me than a growth or value play like it was for me at first. I look for it to be overbought (sell it) or oversold (buy it). Obviously I am expecting (and betting on) a rebound from this level.
So yesterday was a sell day, nice profits put in the bank. Today's a buy day.
