Crypto ETF flows swung sharply into negative territory on Friday as investors pulled back from Bitcoin funds, reversing the steady inflows seen earlier in the week. Analysts attribute the withdrawals to profit-taking and renewed caution after recent price volatility. Bitcoin ETFs saw the largest outflows, dragging overall digital-asset investment products into net negative territory for the day. Market watchers say sentiment remains fragile, with traders waiting for clearer signals on interest rates, regulatory moves and short-term price direction before re-entering riskier crypto-linked instruments.
