BlackRock has transferred 4,653 Bitcoin and 57,455 Ethereum, valued at over $673 million, to Coinbase Prime. This significant transaction occurred on October 6, following a $114.97 million Ethereum deposit to the same address just a day earlier. The batched nature of these transfers suggests strategic institutional positioning, possibly linked to ETF liquidity needs. The timing of BlackRock's move has sparked speculation about a potential shift in its bullish outlook on cryptocurrencies, especially as it coincides with a broader market downturn. This development has raised concerns among traders about the implications for market stability and future price movements.
