Why use it. A classic gauge of holding: it grows when holders sit tight and falls when old coins are sold. How to read it. Rising means more coins are passing a year unmoved; falling means old coins are being spent, as in bull markets.

Calculation. Exact definition: BTC held in unspent outputs at least 365 days old, summed across the UTXO age bands from 1–2 years to 15+ years. Higher values mean more BTC in outputs that have not moved for at least 365 days. Age is measured from block-header timestamps in fixed 365-day years; it is not owner holding time or evidence of lost keys. Closed UTC days only, with no carry across missing inputs; source revisions, publication holds and the weakest band's finality carry through. a+b+c+d+e+f+g: the sum of the UTXO age bands 1–2 years, 2–3 years, 3–5 years, 5–7 years, 7–10 years, 10–15 years and 15+ years. The bands come from locally validated Bitcoin Core data, with age from header timestamps in fixed 365-day years, using 40-digit Decimal arithmetic.
