U.S. spot $BTC ETFs posted their strongest single-day performance in nearly a month on Monday: On October 19, they saw net inflows of $526.6 million, the highest daily total since September 22. The dramatic part? Almost all of that money came from BlackRock—$IBIT attracted $665.2 million in a single day, the only one of the 12 funds to see inflows; Fidelity and Grayscale, meanwhile, saw $138.6 million in redemptions. Institutions aren’t sitting out—they’re just backing BlackRock. #Bitcoin #ETF
