Fact Check
The figure of $23.56 million matches the reported weekly net inflow for Ethereum Spot ETFs for the first week of March 2026 across multiple sources (Whale Alert, Cointelegraph). The narrative of BlackRock leading inflows while Fidelity experienced outflows is also supported by market data from that week, where Fidelity's FETH saw significant daily outflows (e.g., $82M on March 6) while BlackRock's ETHA maintained a stronger net position over the 5-day period.
