Grayscale Investments has taken a significant step towards expanding cryptocurrency investment options by filing an S-3 form with the U.S. Securities and Exchange Commission (SEC) to convert its Zcash (ZEC) Trust into a spot Exchange Traded Fund (ETF). This move, reported by Solid Intel, signals a growing institutional interest in ZEC and could potentially open up access to Zcash exposure for a wider range of investors. A spot ETF directly holds the underlying asset, in this case, Zcash. If approved, this ZEC ETF would allow investors to gain exposure to the cryptocurrency without directly holding ZEC tokens themselves, simplifying the investment process. The SEC's decision on Grayscale's application will be closely watched by the crypto community as it could set a precedent for other digital assets seeking ETF status. ```
