BlackRock's recent move is quite interesting — transferring 74,973 ETH and 2,257 BTC to a certain compliant platform all at once. What does such a large asset reallocation usually signify? Some say it's to increase liquidity, while others believe it might involve derivatives strategies. Regardless, this massive transfer once again confirms traditional financial institutions' ongoing involvement in the crypto market. BTC and ETH, as mainstream assets, have always been a key focus for institutional allocation. From on-chain data, the movements of such large holders often reflect subtle shifts in market sentiment.
