Dude the value of BTC has just increased almost 20% in a day. If it drops by anything close to that, hordes will descend and buy in more. People feeling queasy at $50 earlier today won't miss the boat twice.
There will be a minor drop (sharp sell followed by sharp buy), but nothing to fret about. Hold onto your coins, and if you're quick enough, buy more on the inevitable rebound.
If you try to sell like some sort of crazed daytrader, more likely than not you will hopelessly miss the top and be buying back at a higher price in a few days.
Fixed that for you
