I don't buy it either. ZEC is actually the coin. People always go to it when market is falling. Look even today ZEC was gaining value over BTC well before the market turned around. And then pumped hard and still up 13% over BTC while ETC not even 1%.

I do wonder when people can't mine ETH, they will move to ZEC and the diff will skyrocket. Hope not.
