最新报道:Grayscale Investments launched the Ethereum Covered Call ETF (ETCO) on September 4, 2025, an actively managed fund designed to generate bi-weekly income through a covered call strategy on Ethereum ETPs. With a 0.66% expense ratio, ETCO collects premiums by writing call options on Grayscale’s Ethereum Trust products, aiming to provide downside protection while limiting upside gains. The ETF does not directly hold digital assets but uses derivatives tied to Ethereum ETPs, complementing Grayscale’s existing income-focused offerings like BTCC and BPI.
