According to Farside Investors (@FarsideUK), the weekly summary of Bitcoin ETF flows shows a total net outflow of $144.8 million, with notable inflows into IBIT ($584.6M) and significant outflows from ARKB (-$281.9M), FBTC (-$198.8M), and GBTC (-$134.4M). The net negative flow suggests investor caution in the current crypto environment, which may signal short-term volatility and impact Bitcoin price action as major ETFs experience withdrawals (source: Farside Investors, May 31, 2025). Traders should monitor ETF flow trends closely, as they provide real-time sentiment indicators for the broader cryptocurrency market.
