Zcash

Zcash is an decentralized and open-source cryptocurrency launched at the end of 2017. Zcash is an extremely popular fork of the Bitcoin Protocol. "If Bitcoin is like http for money, Zcash is https," that's how Zcash defines itself on their website.
Thus, like https, Zcash offers both shielded and transparent transactions that vary in whether or not the amount and recipient of a transaction are private or not. Zcash's blockchain shows only that a transaction took place, not who was involved or what the amount was.

ZCash is very popular among miners as it is more profitable than most of the other altcoins, due largely in part to its 2.5-minute average "block time", 2mb block-size, and 12.5 ZEC per mined-block reward.

Although it was launched at the latter end of 2016, Zcash is already on the list of top ten trading cryptocurrency by volume. The market cap of zcash is $569,440,051 with a price of $224.17 per unit. Z-cash can be said as one of the top cryptocurrency to invest besides bitcoin 2018
