Age of coins deposited into exchanges — Modeled history + exact live tail through analytical block #{{block}}
The age of spent outputs carried into labeled exchanges, split from brand-new coins through 10-year-old supply.
Young-band inflow is normal trading churn. A sudden expansion in the 1y+ or 5y+ bands means experienced holders are moving dormant supply where it can be sold.
Before exact block-level collection, the historical baseline uses a maximum-entropy age allocation constrained by measured exchange inflow BTC and CDD. Exact callback data replaces the live tail.
