This is panic momentum on the part of the beholders of ethereum. Once in a bluemoon this take place. The crash sounds not familiar in this present age coz ethereum is not so long anyway from the day it was created. The making of ethereum is vital now if it will crash so far or it will recover as soon as possible.
Well, this is not the first time. And not the last one! Such a jump people "from the upper society" specifically do to scare the total mass, and they began to sell the eth, and the other part of the population bought it. Thus, by falling, in the future, by driving a coin, they pass it, people spend it and buy even more, it does not stand still, it circulates from hand to hand. Someone loses money on this, and someone earns, and quite well.
If possible, wait for the maximum drop, buy the ethereum, and when we pass the pump, sell and earn!
