Winklevoss Twins File for Zcash ETF Under Ticker WINK

The Winklevoss twins have filed for a spot Zcash ETF. The fund would trade on Nasdaq under the ticker WINK. For anyone who wants a privacy coin in a regular brokerage account, it is one more option.

What exactly was filed with the SEC

According to Decrypt and The Block, Cameron and Tyler Winklevoss registered an S-1 on Monday. The fund would buy ZEC directly and track its price. The sponsor fee is 0.25% a year. Gemini, the twins' own exchange, would keep the coins in cold storage.

There is a money detail too. Winklevoss Capital Fund hinted it is ready to buy up to $100 million of the shares. The filing says plainly that this commitment is non-binding. Still, the signal is easy to read: their own cash is on the table, not just paperwork.

Who already holds this ground

There is a rival. Grayscale turned its Zcash Trust into a spot ETF in August, then moved to split the shares. In Europe, 21Shares launched the first exchange-traded product on Zcash. The Winklevoss filing is one more attempt to wrap a privacy coin in a familiar package.

Cypherpunk Technologies will advise on protocol matters and coinholder voting. It is a Zcash treasury company that the twins also back. So one family offers the fund, holds its coins and advises on votes. Convenient, but readers should keep that overlap of interests in mind.

A coin that was shunned until recently

Zcash hides the sender, the recipient and the amount of a transfer using zk-SNARKs cryptography. For years, regulators and exchanges looked at such coins with suspicion. This year everything flipped. ZEC climbed into the top ranks of crypto assets and gained over 2,000% in a year.

People fear total financial surveillance, and that feeds demand. This week the US Treasury also withdrew its mixer rule, which critics called too broad. The mood of the market is shifting, and the Winklevoss twins do not seem to want to miss the wave.

Risks the twins do not hide

The documents name the risks openly. ZEC volatility is extreme. Privacy coins have their own vulnerabilities. The filing separately mentions a bug found this year in the Orchard shielded pool. It briefly sent the price down about 50% until the network closed the hole with the Ironwood upgrade.

• The SEC must approve the fund, and there will be no trading before that.
• The coin is up 2,000% in a year, so a drop can be sharp too.
• The 0.25% annual fee eats part of the profit, and the custodian adds its own risk.

What comes next

The filing is only a first step. Once spot ETFs became routine for Bitcoin and Ethereum, the market started hunting for the next candidates. Zcash looks like the loudest of the niche coins. Several funds on one asset usually push fees down, which is good for investors. We will watch whether the SEC gives the green light before year end.
