Ethereum News Today: Grayscale Engineers Make Profits Amid Ethereum's Volatility Rises

Grayscale Investments launched the Ethereum Billion Call ETF (ETCO) on September 4, 2025. This active management fund aims to generate profits every two weeks through a call option strategy for Ethereum ETP. ETCO's fee rate is 0.66%, charging a premium by issuing call options on Grayscale's Ethereum Trust product, aiming to provide downside protection while limiting upside gains. Instead of holding digital assets directly, the ETF uses derivatives linked to Ethereum ETP to complement Grayscale’s existing earnings-focused products such as BTCC and BPI.
