US spot Bitcoin ETFs pulled in $297.5 million on August 17, led by BlackRock's IBIT at $160.2 million and Fidelity's FBTC at $112 million, reversing three consecutive days of redemptions. Weekly flows remain choppy, with more than $385 million having left the funds the prior week, so the session reads as a sharp reversal rather than a settled trend. Bitcoin's market dominance has climbed to 59.3% as capital consolidates out of altcoins.
