According to Farside Investors, the Bitcoin ETF daily flow for Grayscale's GBTC registered zero net inflow on May 28, 2025 (source: FarsideUK on Twitter). This stagnation in ETF movement highlights a pause in institutional demand, which may signal short-term price stability or reduced volatility for Bitcoin. Crypto traders monitoring ETF flows should note this flat activity, as ETF inflows and outflows are often leading indicators for Bitcoin price trends and overall crypto market sentiment (source: farside.co.uk/btc/).
