I think the really reasons why this altcoins is dumping down is bitcoins is gainings its price again in $1200 mark.As you may have observe when bitcoins price is at dumps altcoins like eth and dash are pumping its price and now thats bitcoins is gaining price again viceversa effect will happen.i think that is why and that is what i conclude in this happenings
the really real reason was that these altcoins were pumped and when an altcoin price is fake that means the bubble it is in will burst sooner or later. and as we see today, it is bursting hard.
bitcoin was just an excuse they used, there is no other reason for them rising. this FUD thing with BU was a perfect set up for them to pump their coins with the moto of "we are replacing bitcoin".
Meanwhile ripple is up by 100%, litecoin by 9%, bitshares by 30% and doge by 40%, what is life.
life is if you can join these when price is low and dump them hard when it is on top not waiting for them to go higher which will never happen.
