Zcash seems to be moving upward since March. The price accelerated in early April riding a market spike. It did reach a high of $78 on Apr 3, but Zcash started trading downward again. I saw an article recently in beincrypto, it talks about these predictions: The price trading around $175 in December 2019. The price could trade around $685 in December 2020. there were some analysis on patterns, but of course its hard to validate of any pattern in years time.
