According to Cas Abbé (@cas_abbe), BlackRock recorded its second largest daily Bitcoin inflow with nearly 10,243 BTC purchased, equivalent to $970.93 million. The last comparable inflow occurred on November 7th, after which Bitcoin surged 40% over five weeks. This substantial institutional investment is a key trading signal for bullish market sentiment, suggesting potential upward price action based on historical inflow-driven rallies (source: Cas Abbé on Twitter, April 29, 2025).
