ETH broke down the lowest trendline I have drawn on December 8th. One more time it is a resistance line for ETH. If BTC bullrun ends soon, ETH will break out and continue its bullrun. On the other hand, if BTC continues to climb (and if you consider the CME, CBOE and TD Ameritrade BTC additions today, I would expect a huge BTC dump as we have experienced on CBOE BTC addition occasion.
