According to Cas Abbé on Twitter, BlackRock purchased 5,600 BTC worth $531 million yesterday, while Fidelity, Bitwise, and Grayscale were selling their holdings (source: Cas Abbé, May 6, 2025). Despite this large acquisition, the Bitcoin price did not spike because BlackRock executed the trade primarily through over-the-counter (OTC) channels, which do not directly impact spot market prices. Traders should monitor OTC activity and potential future supply crunches, as these large institutional moves could have delayed effects on Bitcoin market liquidity and price action.
