According to Farside Investors, Ark's spot Bitcoin ETF reported a daily flow of zero million USD on June 20, 2025 (source: FarsideUK). This stagnation in ETF inflow may signal reduced institutional interest and can influence short-term BTC price action. Traders should monitor ETF flows closely, as lower inflows have historically correlated with weaker Bitcoin (BTC) momentum. For detailed data, visit farside.co.uk/btc.
