Bitcoin and major alts started going down 2 hours ago. But ZEC took off. That's a GREAT position to be in. What in the world could cause ZEC to be viewed as a safe-haven compared to the other coins? It went up in absolute dollar terms as the others went down so it's not just an exchange rate effect. The traders preferred ZEC over the dollar and other major coins when they got spooked. Things have retraced some, but ZEC is still ahead and it's those sudden instantaneous moves that show people's heart.
Edit: in looking at it further, ZEC has had a nice smooth up trend the past 2 days. That gave it a good base to start from this morning. One thing hurting ETH and Monero is that they had a big jump in the past two days, so their base was more fragile. But these recent accidents do not explain why ZEC went up while they went down when the market was spooked. These are the professional traders doing the short-term moves early Sunday morning, and if they know the future better than others, ZEC has a nice mid-term outlook. Maybe ZEC is more of a U.S. coin and something spooked China and Europe, but still it does not explain the rise.
