Winklevoss Asset Services has filed with the SEC to launch a spot Zcash ETF on Nasdaq under the ticker WINK — a move that could put one of crypto’s best-known privacy coins inside ordinary brokerage accounts, even as investors were pulling money out of the existing Zcash fund last week.

The Hook: A Privacy Coin Goes to Wall Street
The firm, led by Tyler and Cameron Winklevoss — the same twins behind the Gemini crypto exchange — filed an S-1 registration statement with the U.S. Securities and Exchange Commission on Oct. 6. The proposed fund would list on Nasdaq as WINK and hold Zcash (ZEC) tokens directly, rather than tracking futures contracts or derivatives. Gemini Trust Company would serve as the fund’s custodian, meaning it would safeguard the actual coins backing the shares.
The filing also disclosed a proposed 0.25% management fee and indicated that Winklevoss Capital affiliates have eyed up to 100 million USD of nonbinding investment interest in the fund, according to coverage of the registration. The market noticed immediately: ZEC gained more than 5% in 24 hours and was recently trading above 1,376 USD.
On-Chain Evidence: How the Fund Would Actually Work
Under the proposed structure, big institutional middlemen known as authorized participants would use cash, not coins, when creating or redeeming ETF shares. In practice: a participant delivers dollars, the fund buys ZEC with that cash, and Gemini holds the tokens. When investors cash out, the process reverses. Think of it like a vending machine — you insert dollars, the machine handles the inventory, and you never touch the goods directly.
That design keeps the crypto handling entirely inside the fund, which is the same arrangement regulators have grown comfortable with for Bitcoin and Ether funds. The filing does not set a launch date — the fund still needs regulatory clearance before WINK can begin trading.
The Core Conflict: Optimism From the Winklevoss Camp, Money Leaving the Rival Fund
Here’s the puzzle for investors. Zcash already has a spot ETF: Grayscale converted its nine-year-old Zcash Trust into an exchange-traded product on NYSE Arca on Aug. 25 under the ticker ZCSH, with roughly 304 million USD in assets at launch, a 2.50% management fee directed toward Zcash ecosystem development, and Coinbase as custodian.
But appetite has cooled. For the week ended Oct. 2, Grayscale’s Zcash ETF recorded 93.56 million USD in withdrawals, its first negative week since late August, according to SoSoValue data cited by crypto.news. Daily net outflows reached 30.25 million USD on Sept. 30 and 26.93 million USD on Oct. 2. The fund still holds approximately 751 million USD in net assets, with cumulative net inflows of about 212.56 million USD since conversion — so it remains substantial, but the recent direction of travel has been out, not in.
There’s also a technical deadline looming over the market: Zcash developers have scheduled an Oct. 20 decision on the NU7 upgrade’s proposed November mainnet activation. Network upgrades are moments when a chain either strengthens its privacy and performance credentials or stumbles — and traders know it.
Market Implications: What This Means for Regular Investors
ZEC’s recent ride has been dramatic. CoinGecko historical prices show the coin closing at 1,653.12 USD on Sept. 26 and 1,304.32 USD on Oct. 3 — a steep pullback before the ETF news helped push it back above 1,376 USD. Meanwhile, the broader crypto market was under pressure Wednesday, with Bitcoin trading near 82,800 USD and Ether near 2,555 USD, both down on the day.
Why does an ETF filing matter to someone who already owns ZEC in a wallet? Two reasons. First, an exchange-traded fund lets retirement accounts and brokerage portfolios gain exposure to Zcash — money that can’t easily buy coins on an exchange today. Second, competition tends to be good for costs: WINK’s proposed 0.25% fee is a tenth of what Grayscale’s ZCSH charges, and fee pressure historically forces incumbents to cut.
The Verdict
A spot Zcash ETF from the Winklevoss camp is a genuine milestone for privacy-coin legitimacy — Wall Street custody for an asset designed to keep transactions private. But investors should hold two facts in tension: a new low-cost fund is coming, while investors in the existing fund just pulled nearly 94 million USD in a single week. The filing is a long-term credibility signal, not a guarantee of short-term gains, and S-1 filings can take months to clear. If you own ZEC, the practical takeaway is that your asset is getting closer to the mainstream financial system — with all the volatility that journey brings.

a privacy coin inside a Nasdaq ETF is wild. the whole point of ZEC is opt-out privacy and now it will sit in boomer brokerage accounts lol
a privacy coin ETF with fully kyc’d authorized participants and Gemini holding the keys. the irony is lost on nobody i hope
thats literally the only way institutions touch ZEC. 0.25% fee for that access is honestly cheap, cheapest privacy exposure a brokerage account will ever see
fully traceable ZEC in an ETF wrapper. the shielded pool usage is the part regulators will pretend not to see
shielded pool is opt in tho, fund can hold transparent zec and the privacy crowd loses nothing
custodied spot means the fund holds transparent coins anyway. the shielded pool keeps existing for people who want privacy, the etf is for the brokerage crowd
Shielded pool usage keeps sliding anyway. ETF demand and privacy demand are two separate user bases at this point, the fund can exist without cannibalizing either.
the authorized participants never touch shielded zec either, its transparent coins all the way down. the irony is structural lol
transparent coins all the way down is the punchline. the fund exists precisely because it strips out the one feature zec is famous for
Winklevoss twins file for a Zcash ETF the same week investors pulled money out of the existing ZEC fund. somebody is betting retail buys anything with ETF in the name.
exactly, and privacy coins are delisted on half the big exchanges. how does an ETF sponsor even handle that compliance mess
ZEC up only 5% on a Winklevoss filing with 100M of interest flagged? Id have expected a proper candle, not a shrug
5% on an S-1 filing is actually decent. its the approval that prints, filings are chapter one
5% is the front-run crowd taking profits. wait for the actual approval window, thats when this gets loud
or it never gets approved and zec keeps drifting. privacy coin S-1s are uncharted territory for the sec
hard disagree, the sec already approved futures products with messier collateral than a custodied spot coin. if gemini custody cleared the bar for the btc etfs, wink’s real hurdle is privacy optics, not the s-1 structure
privacy optics is the whole fight, agreed. a sec comment period that drags in shielded pool stats would be the real headline risk
5 percent on an s-1 is the market finally learning how long these take. the btc spot filings barely moved either until the approval window actually opened
5 percent on an s-1 is the market finally learning the process. filings stopped printing years ago, approvals do
0.25% fee with gemini custody. the twins really said privacy for people who file everything with the SEC
0.25 percent for transparent zec in a brokerage wrapper, cheaper than the privacy premium people paid taking mixer risk. the irony pays dividends
ticker WINK is perfect and they absolutely know it
zec over 1300 and a nasdaq etf filing in the same week. 2021 me would have called this simulation broken
the existing zec fund bled outflows for months and the twins still file. conviction or inventory, pick one
twins filing WINK while the existing zec fund bleeds outflows is either contrarian genius or inventory management. the approval decision settles it
