According to Farside Investors, Ark's Bitcoin ETF experienced a significant daily net outflow of $34.3 million on May 28, 2025 (source: FarsideUK via Twitter). This marked outflow signals heightened investor caution and may contribute to short-term bearish sentiment in the broader cryptocurrency market. Traders should monitor Bitcoin ETF flows as they often act as leading indicators of institutional confidence and can influence spot Bitcoin price volatility. Continuous tracking of ETF fund movements remains critical for making informed trading decisions in the current market environment.
