BlackRock and other ETFs just dumped $450.33M worth of $BTC — the largest single-day outflow in 3 months.

This isn't noise. When institutional money moves this fast in one direction, it's rarely random. A few things to watch:

1. Macro context matters. Fed hawkish pivot? Risk-off rotation into bonds? Or just profit-taking after the rally?

2. ETF flows are a lagging sentiment indicator, not a leading one. Retail and institutions often sell after price drops, not before. So this could signal capitulation or just rebalancing.

3. Compare this to inflows during the rally. If net positioning is still positive over a 30-60 day window, this is just volatility. If it's the start of a trend, we'll see follow-through in the next 1-2 weeks.

4. BlackRock specifically matters because they're the largest player. If they're leading the outflow, it's institutional capital repricing risk. If it's smaller ETFs, it's less systemic.

Bottom line: largest outflow in 3 months is a data point, not a thesis. Watch for confirmation in price action, funding rates, and whether spot demand from Asia or other regions absorbs the selling pressure. If $BTC holds key support despite this, that's actually bullish. If it breaks down, this was the early warning.
