Grayscale has staked 304,000 ETH, valued at over $1.3 billion, through its Ethereum Trust ETFs, allowing investors to earn staking yields via traditional brokerage accounts. Despite this strategic move, Ethereum's price has dropped below $4,500, down from over $4,700 in October. The decline is compounded by a large unstaking queue of over 2.4 million ETH, indicating potential selling pressure. Additionally, significant movements by Ethereum whales and Bitcoin OG wallets are contributing to the downward price momentum. These activities suggest a broader trend of selling among major holders, further impacting Ethereum's market performance.
