According to Farside Investors, Grayscale's Bitcoin Trust (GBTC) experienced a significant daily outflow of $89.9 million on May 6, 2025 (source: FarsideUK on Twitter). This substantial withdrawal signals persistent bearish sentiment among institutional investors and could exert downward pressure on Bitcoin's short-term price action. Traders should closely monitor ETF flows as continued outflows from major funds like GBTC often correlate with increased market volatility and potential selling momentum in both spot and derivative Bitcoin markets.
