I think that the reason behind all of this is Chinese people cashing out their money for the lunar new year and thus bitcoin has  went down , it is much  similar to what happened in last Christmas but at a bigger scale and no one should be worried about all of this dumping because bitcoin has proved itself able  to grow back (even if it may take a little longer to do so this time ) .
People are more and more spreading FUD everywhere and any holder is having "on paper loss" at the moment , he'll be at a real loosing condition if he sells his funds for a lower price , therefore HOLD YOUR FUNDS !
