US spot Bitcoin ETFs have never logged more than four straight months of outflows. Not even once since launch. Even after that ugly Nov-Feb stretch in late 2025/early 2026 where they bled hard for four months, they flipped positive and stayed under the five month mark. October’s red again at -617M so far, assets still $104B with BTC ~$81.5k. My take: actually bullish. Institutions rotate and take profits but the bid always comes back. Four months max of pain shows real strength, not weak hands. Short-term chop sucks but this flow history screams the floor holds. Keep stacking if you’re multi-year set-up.
