Spot Bitcoin ETFs posted $201.9 million in net outflows on August 28, ending a nine-day consecutive inflow run. At 1.42 standard deviations below the 30-day average daily flow of $109.3 million, the outflow is elevated but not historically extreme. Single-day reversals after multi-day inflow streaks are a recurring pattern; the signal becomes more meaningful only if outflows persist across several sessions.
