ETH is related for me it's pretty obvious that some whales have been involved in the BTC crash. They just profited from the bitfinex incident to use this sell off traction while pumping ETH. This makes BTC holders to psychologically see ETH as a place to be while BTC corrects. Dont fall for it.
ETH is sort of a speculation coin and it value increase and decreased mostly by speculation. If you are a serious looking for a long term investment, Go for bitcon and do not panic for little dumps of bitcoins on the way.
