Zcash was garbage in 2016, still garbage in 2017. Good luck overcoming Monero's network effect. If in doubt, compare Zcash's subreddit to Monero's. Monero has about 5x more subscribers, and is more than 5 times as active as the Zcash subreddit. In other words, Zcash is astroturf nonsense, no real world use or organic interest to speak of.
Go to DNM communities and see which coins are being mentioned. Spoiler: Bitcoin and Monero. Anything else is treated like pump and dump garbage, which is what Zcash is. A scheme to enrich Zooko and company. It'll go to zero once Ethereum adds zk-snarks.
No one is talking about Zcash. This thread is about Zcoin.
