Zcash Holds Above $510 as Privacy Coin Draws Renewed Trending Interest
Zcash (ZEC) held above $510 on May 17 as the privacy-focused cryptocurrency posted $386.3 million in 24-hour trading volume, placing the asset among the top-trending coins on CoinGecko. ZEC gained 1.5% in the same period against the U.S. dollar, a modest absolute move that stood in contrast to the scale of its volume.
The coin held a market cap of $8.48 billion and ranked 16th globally by that measure.
The ZEC Price Picture on May 17
ZEC’s 24-hour gain of 1.5% against the dollar was accompanied by a 2.8% gain against Bitcoin, suggesting mild but real relative strength. The price held at roughly $511, with the token valued at approximately 0.00655 BTC.
Against Ethereum, the 24-hour advance reached 3.5%.
The trading volume of $386.3 million represented roughly 4.6% of ZEC’s total market cap, a ratio that indicates active but not extreme turnover for a top-20 cryptocurrency. For context, that volume figure places ZEC among the more liquid privacy-focused assets in the market on a per-session basis.
The CoinGecko trending score placed ZEC third among all trending assets at scan time, behind Osmosis (OSMO) and Billions Network (BILL).

How Zcash’s Privacy Model Works
Zcash is a cryptocurrency that uses zero-knowledge proofs, specifically a construction called zk-SNARKs, to allow users to send fully encrypted transactions while the blockchain still verifies validity without exposing sender, receiver, or amount. Zero-knowledge proofs are a cryptographic method in which one party can prove knowledge of a fact to another party without conveying the underlying information itself.
Zcash offers two address types.
Transparent addresses function identically to Bitcoin addresses and expose transaction details on the public ledger. Shielded addresses use zk-SNARK proofs to encrypt transaction data entirely.
The distinction matters for regulatory discussions because most ZEC transactions historically have used transparent addresses, meaning the shielded feature is used by a minority of participants despite being the protocol’s primary technical differentiator.
The protocol was developed by the Electric Coin Company and launched in October 2016. A portion of block rewards was allocated to the development team and foundation through a mechanism called the Founders’ Reward, which expired in November 2020.
Subsequent funding has come through a Community Development Fund that allocates a share of block rewards to the Electric Coin Company, the Zcash Foundation, and a grants program.

Background
Privacy coins have faced sustained regulatory pressure since 2020, when several major cryptocurrency exchanges delisted ZEC, Monero, and Dash in response to guidance from financial regulators in Japan, South Korea, and the United Kingdom. Zcash’s transparent address design has helped it avoid some of the harshest enforcement actions, since regulators and exchanges can point to on-chain auditability when users transact through transparent addresses.
The broader privacy cryptocurrency conversation resurfaced in 2025 as data-breach incidents and surveillance concerns pushed a segment of cryptocurrency users toward assets with stronger confidentiality guarantees.
Zcash’s position at rank 16 by market cap makes it the most liquid privacy-focused cryptocurrency available on major regulated exchanges. The Nonce backgrounder on Zcash’s design covered its technical architecture in depth.
The Electric Coin Company has continued developing the Zcash protocol toward a major upgrade called Zcash Shielded Assets, which would extend shielded transaction support to custom tokens issued on the network.

What to Watch
ZEC’s position in the trending list without a sharp price move suggests search and attention interest rather than a momentum-driven trade. Traders and analysts watching ZEC will want to track whether volume stays above $300 million per day in the sessions following May 17, which would indicate sustained interest rather than a single-day attention spike.
Any regulatory announcement targeting privacy cryptocurrency specifically, or any new exchange listing or delisting of ZEC, would likely move the price more than pure volume does.
The asset’s rank-16 position makes it the most visible target in the privacy coin category if regulators update guidance on shielded transactions.
