US spot Bitcoin ETFs saw a net inflow of $101.15 million on September 2, rebounding sharply after a $236.5 million outflow the day before. BlackRock's IBIT led with $115.45 million in new capital, while Grayscale's GBTC continued to experience significant outflows as investors shift to lower-fee alternatives. Meanwhile, spot ETFs for Ethereum, Solana, and XRP all recorded net outflows, indicating a focused institutional interest in Bitcoin rather than altcoins.
