June often sees institutional portfolio rebalancing, and after the strong rally that preceded it, many funds likely locked in gains before the end of the quarter. Also, any hawkish signals from the Fed or shifts in liquidity expectations can trigger a pullback in risk assets like Bitcoin. But remember, outflows don't always mean bearish sentiment—sometimes it's just smart money moving. Always check the official ETF data on the Coinmeta site for exact figures.
