Farside Investors recorded a net inflow of $526.7 million to U.S. spot Bitcoin (BTC) ETFs on Oct. 19, after $228.4 million in outflows from Oct. 12-16; the longer comparison showed no consistent advance signal.
The comparison covered 694 trading sessions after the funds began trading in January 2024. Each of the nine sampled periods with a Bitcoin gain of at least 15% coincided with net ETF inflows. Of eight periods with losses of that size, seven had net outflows.
The tally cannot identify what drove either price moves or fund flows; it records their direction within the selected periods.
