BTC remains structurally resilient, but weakening spot demand, slowing ETF inflows, and increasingly crowded long positioning suggest upside momentum is cooling down.

Executive Summary
- BTC reclaimed True Market Mean at $78.3k but couldn't hold. History suggests weeks to months of consolidation needed before a bull transition.
- 30D SMA of Realized P/L Ratio jumped from 0.4 to 1.8 during the rally. Needs a sustained move above 2 to confirm real buy-side recovery.
- 30D cost basis at $78.2k flipped from support to resistance. The Feb-April cohort at $71.4k is the next support floor.
- Spot internals have weakened. Aggregate Spot CVD stays negative and Coinbase lags, pointing to softer US institutional demand.
- CME Futures OI keeps recovering with price, showing better institutional participation in derivatives.
- US Spot ETF inflows are slowing, leaving futures to drive positioning as spot demand fades.
- Options positioning stays defensive. Skew shows demand for downside hedges.
