According to Crypto Rover, BlackRock has transferred 27,852 ETH, valued at approximately $43 million, to Coinbase. This significant movement of Ethereum could indicate potential market volatility or a strategic move by BlackRock. Traders should closely monitor Ethereum's price action and trading volumes following this transfer as it may signal an impending sell-off or strategic reallocation of assets. Monitoring on-chain data and Coinbase's order book could provide insights into BlackRock's intentions.
