It's funny how all the Mr hindsights are out in force today. Let's face it, nobody predicting this would happen, when we were sat steady at $6200 - $6500 for months nobody mentioned a huge drop was coming. Now all of a sudden Bitcoin drops down to $4400 and everyones piping up saying "i told you this was coming" or "you should have sold in January" blar blar blar.
Both sides are full of crap, people who say this is going to down to $1000 and also people saying you should buy now because these prices are great.
My advice - if you need to unlock the capital in your bitcoin, by all means sell it now. But don't be too disapointed if this downtrend suddenly turns around in the coming weeks. Nobody knows if its going to tank down to $1000 or if its going to swing around and we're due another bull run before xmas.
Personally i'll be sitting on the sidelines watching with interest.
