Grayscale's Ethereum Staking ETF (Ticker: $ETHE) has become the first U.S. Ethereum exchange-traded product (ETP) to distribute staking rewards to its investors. This marks a significant development in the cryptocurrency investment landscape, as it allows investors to receive direct benefits from Ethereum staking activities. The ETF is trading ex-dividend today, meaning that new buyers will not receive the upcoming dividend payout. This move by Grayscale could set a precedent for other cryptocurrency ETFs to follow, potentially increasing the attractiveness of staking-based investment products.
