According to Crypto Rover, BlackRock has executed a significant portfolio adjustment by selling $130.4 million worth of Bitcoin (BTC) and purchasing $48.4 million worth of Ethereum (ETH) (source: Crypto Rover on Twitter, June 3, 2025). This capital rotation from BTC to ETH suggests BlackRock may be positioning to capture potential upside in Ethereum, which could influence broader market sentiment and trigger similar reallocations among institutional investors. Traders should closely monitor ETH/BTC trading pairs for volatility and potential trend reversals as this move could signal a shift in institutional preference within the crypto market.
