最新报道:Grayscale has launched the Ethereum Covered Call ETF (ETCO), designed to generate steady income by selling call options on Ethereum-linked products. The fund distributes premiums bi-weekly, targeting investors seeking cash flow amid ether's 34% year-to-date gains, which outpace bitcoin's 20% rise. ETCO aims to monetize ether's volatility while providing a buffer against downside risk.
