According to Farside Investors, the total net flow for US spot Bitcoin ETFs on June 20, 2025, was $6.4 million, with BlackRock's IBIT leading with a strong $46.9 million inflow, while Fidelity's FBTC recorded a significant outflow of $40.5 million (source: FarsideUK, Twitter, June 21, 2025). No notable flows were observed in other major ETFs like BITB, ARKB, BTCO, EZBC, BRRR, HODL, BTCW, or GBTC. The dominance of IBIT's inflows suggests continued institutional confidence, while FBTC's outflow could signal profit-taking or rotation between funds. These ETF flow dynamics are closely watched by traders for short-term BTC price direction, as net ETF inflows often correlate with positive momentum in the cryptocurrency market.

According to Farside Investors, Ethereum ETF net inflows totaled $78.2 million on June 2, 2025, with ETHA capturing $48.4 million and FETH securing $29.8 million, while other funds reported no new flows (source: Farside Investors on Twitter, June 3, 2025). This significant capital injection into ETHA and FETH highlights robust institutional interest, signaling potential upward momentum for Ethereum’s price in the short term. Traders should closely monitor ETH ETF flows, as increased inflows often precede price volatility and can serve as early indicators for trading opportunities in the broader crypto market.
