According to Farside Investors (@FarsideUK), the Grayscale Bitcoin Trust (GBTC) reported zero million dollars in daily ETF flows on May 21, 2025. This flat inflow indicates a pause in institutional Bitcoin demand via GBTC, which may signal short-term consolidation in the broader crypto market. Traders monitoring ETF inflows should note that stagnant flows can reflect decreased market momentum and lower volatility in Bitcoin trading activity (source: Farside Investors, May 21, 2025).
