Method & caveats
- Bewusster Zuschnitt auf die Mature-Era ab 2018-12-01; die Extremjahre 2011–2017 sind ausgenommen und würden die Kennzahlen stark nach oben verzerren (offengelegter Researcher-Degree-of-Freedom).
- Unbedingte Single-Asset-Basisrate → implizit konditioniert darauf, dass BTC überlebt hat (inhärenter Survivorship-Bias bei Single-Asset).
- Median/Quantile sind die belastbaren Kennzahlen; der Mean ist über überlappende Jahres-Fenster autokorreliert und von wenigen Bull-Run-Start-Clustern dominiert (bei wenigen unabhängigen Jahren fragil).
This is the unconditional base rate. For the view conditioned on today's market fingerprint, see the historical analogues.
