Many people here are breaking down the charts on the short-to-mid-term, but just take a look at the weekly chart. Between the weekly and the obvious cup and handle and numerous bullish signals you can spot on the 4 hour and dailies, ZEC is possibly my favorite long-term bet. It may yield results faster than anticipated.
ETH and LTC are getting a lot of attention lately as the favorite altcoins to rise, but I think ZEC is going under the radar as the best pick. It has the most pressure, it's the farthest from it's ATH's in terms of percentages, and I'd say it has the most to rise. Let everyone ditch their coins and FOMO chase ZEC after you're already in.
