Fact Check
The claim is precisely corroborated by reports from PANews and TechFlowPost, which cite SoSoValue data for the specific trading week of March 16–20, 2026. The details regarding BlackRock's IBIT ($191M inflow) and Fidelity's FBTC ($50.07M outflow) match the source data exactly. A slight variation in the total figure ($93.1M) reported by BlockBeats is attributed to a different data aggregator (Farside), which is standard in crypto market reporting.
