you should do that thing if you got an accurate forecast of the bitcoin price and it would be much better if you're going to sell your bitcoins if it's going to drop and if it's surely happen, since the last three days I didn't see any drop even a bit . anyway you don't need to panic, it's normal that the price will drop a little bit and it will surely go back with a much higher value .
Come on dude, OP might have already settled his things back after he sold his coins. He said that he thought that he would sell, but nobody knows whether he did or not. If he took action, he must be in some profit currently, profit of gaining some extra coins at lower rates with the opportunity to sell them back higher and if he didn't, it still doesn't make any difference as the price is still high and he will still be making something out of his coins.
