According to Farside Investors (@FarsideUK), Ark's Bitcoin ETF experienced a significant daily net outflow of $73.9 million on June 2, 2025. This marked negative flow signals reduced institutional confidence and can increase short-term volatility for Bitcoin price action, as large outflows often put downward pressure on spot markets (source: FarsideUK). Traders should closely monitor ETF flows as they remain a leading indicator for broader crypto market sentiment and potential price swings.
