Bitcoin Tests $80K Cost Basis of ETFs, Treasuries as Fed and MSCI Loom

The dip into the $80K–$81.5K band is a stress test of the marginal holder: that zone now marks the average cost basis for both U.S. spot ETFs and corporate treasuries, so a sustained break below would put a large, identifiable cohort underwater and could turn passive holders into a supply overhang. The offsetting signal is the $653 million ETF inflow, which suggests dip-buying is still active even as volumes stay weak — a thin-market bounce rather than broad conviction. The open question is whether that cost-basis floor holds once the Fed and MSCI catalysts resolve, and whether the $85K–$87.5K resistance from 6-to-12-month holders caps any recovery.
