ChainThink report, on March 6, the inflow trend of U.S. spot Bitcoin ETFs was interrupted. Data shows that as Bitcoin price dipped below $71,000, U.S. spot Bitcoin ETFs experienced a net outflow of $228 million on Thursday, ending three consecutive days of approximately $1.1 billion in net inflows.

Specifically, the outflows were primarily driven by iShares Bitcoin Trust (around $89 million), Fidelity Wise Origin Bitcoin Fund (approximately $48 million), and Bitwise Bitcoin ETF (about $46 million). Nevertheless, through Friday, U.S. spot Bitcoin ETFs still recorded a net inflow of roughly $917 million for the week, with assets under management (AUM) remaining above $90 billion.

Analysts indicate that Bitcoin's recent rebound above $73,000 is more likely a "relief rally" rather than the beginning of a new bull cycle. Some institutions have previously warned that, within the current crypto market correction phase, Bitcoin prices could potentially fall below $60,000.

On other crypto ETF fronts, Ethereum-related funds saw outflows of approximately $91 million on the day; XRP and Solana ETFs also recorded minor outflows of $6 million and $5 million respectively. Notably, the Solana ETF experienced its first net outflow since early February.

Nonetheless, market data indicates that Solana has attracted approximately $1.5 billion in net inflows since the launch of its spot ETF in July 2025, demonstrating strong institutional appetite and sustained allocation interest.
