U.S. spot Bitcoin exchange-traded funds recorded $2.31 billion in net inflows across four trading sessions from Sept. 17 through Sept. 22, with BlackRock's IBIT taking in about $1.02 billion, or 44% of the total. IBIT received $183.7 million, $108.4 million, $381.4 million and $350.3 million across the four sessions. The purchases reflected investor demand for Bitcoin exposure through regulated funds rather than direct ownership of the token. Bitcoin later retreated from an intraday high near $87,283 to just above $84,175, a daily decline of 2.35%, while remaining above the $80,000 level cited as a key chart support area. The reported four-session flow total aligns with earlier accounts but conflicts with a separate report that placed a comparable inflow streak in October.
