Winklevoss Asset Services filed a registration statement with the U.S. Securities and Exchange Commission for the proposed Winklevoss Zcash ETF, a spot fund that would hold ZEC directly and seek a Nasdaq listing under the ticker WINK. The fund would charge an annual sponsor fee of 0.25%, use affiliate Gemini Trust Company as custodian and avoid leverage and derivatives. Winklevoss Capital Fund has expressed non-binding interest in purchasing up to $100 million of shares through affiliates. The filing begins the listing process, but WINK cannot launch until its registration becomes effective and Nasdaq approves the listing. Zcash uses zero-knowledge proof technology to support shielded transactions that can conceal transaction amounts and the identities of senders and recipients. Grayscale's Zcash ETF, ZCSH, is already trading in the United States and has announced a 3-for-1 share split. ZEC traded at about $1,354 on Oct. 6, according to the new report, after rising more than 735% over the past year; its market capitalization was about $23 billion, making it the 10th-largest cryptocurrency by market value.
