According to Farside Investors, the Grayscale Bitcoin ETF (GBTC) reported a daily inflow of $6.2 million on May 20, 2025. This positive net flow signals renewed institutional interest and may influence short-term Bitcoin price action, as ETF inflows are often seen as bullish indicators in crypto trading. Traders should monitor ETF flow data closely for signs of market momentum and liquidity shifts, as persistent inflows can support upward price movement and enhance confidence in broader cryptocurrency markets (source: Farside Investors via Twitter).
