Coin Metrics data shows that compared to last year, the users of Zcash, the privacy coin, seem to have decreased significantly. In January 2018, Zcash's active address reached a historical peak of 100,000+. Since then, this number has gradually declined. At first, the rate of decline was quite slow. However, since June-July 2018, the situation has changed dramatically. During this period, the number of Zcash active addresses has almost been cut. After that, for the rest of 2018, this trend cannot be reversed. The number of Zcash addresses currently active is approximately 11,218, which is the lowest value since October 2016.
