According to @CryptoWhale, BlackRock acquired 2,830 BTC valued at $267 million yesterday, but Bitcoin's price declined as rival ETFs — Fidelity, Ark Invest, Grayscale, and Bitwise — collectively sold $323.26 million in BTC, citing recent weak US GDP data as a catalyst for elevated risk-off sentiment (source: @CryptoWhale). This shift in institutional flows highlights the impact of macroeconomic factors on Bitcoin ETF trading and underscores the importance of monitoring ETF inflows and outflows for short-term price direction.
