A macro narrative that turns rolling window diagnostics and regime-aware comparison into a shareable story without pretending the analogy is stronger than it is.
The normalized overlay makes the shared structural windows visible despite the scale mismatch.
The verdict stays interpretable because the radar shows whether the analogy is shape-, trend-, or shock-driven.
The rolling panel shows when the BTC-VIX analogy actually strengthens instead of pretending the relationship is constant.
This story uses a frozen local CSV snapshot built from FRED so the exact comparison can be regenerated later.
