Bitcoin ETF Flows: A Double-Edged Sword in Timing Buys

Investors who bought Bitcoin during September's outflow days paid roughly 9-10% less than those who waited for inflow confirmation to act.

A nearly $1 billion inflow on September 21, 2026, preceded a week of declining prices, making flows better as sentiment context than buy signals.

Monitoring Bitcoin ETF flows may provide a straightforward strategy for making purchases, but it's not the best approach for timing buys, given that flow data often comes out too late and only reflects a portion of buyer activity.
