Short Now! Now! Now!
Most everyday traders expect the price to shoot up after this recent dip. However, $ZEC is currently hitting a major roadblock on the longer-term charts.
I don't think it will break through cleanly right away. Instead, I expect the price to get rejected around $660–$670 and drop back down. A real breakthrough usually requires more market activity and orders to build up first. For now, look for $ZEC to hit that wall and fall toward our target.
