Zcash has formed a descending triangle here, as you can see. It will probably retest 172-173 before continuing to drop further, possibly to 154? A/D shows that Zcash has not been accumulated, nor distributed, so the chance of being dumped is quite high, so don't miss this great drop.
Comment:
Retest range is the price range, not the time range. You can start shorting (aka dumping) ZEC at 172/173 now or later, whatever you prefer.
