BTC: Spent Outputs Aged ≥155 Days — Spent Outputs in Loss — Known Prices

Bitcoin Spent Outputs Aged ≥155 Days — Spent Outputs in Loss — Known Prices was 24,614 outputs on 7 Nov 2026 (latest daily value).

Spent outputs in loss under both prices, for spent inputs at least 155 fixed days old.

Why use it. Compare spent-output frequency separately from BTC value and USD marked gain/loss. How to read it. Strict price inequality, not USD loss size, selects this class. Each output counts once, including zero-value outputs. Zero selected count does not establish complete price coverage; an observed empty flow gives zero, while unobserved flow stays unknown. Age is max(0, spend-header time minus creation-header time); the older group includes ages of 155×86,400 seconds and above. Read known/unknown BTC and price coverage alongside these values. Unobserved history stays unknown; genuine source/price holds and partial/provisional/final labels remain in force.

Calculation. Count spent outputs whose admitted period-start quote is strictly below creation-day basis. Pool inputs consumed by canonical non-coinbase transactions by spend-header UTC period, including eligible spent coinbase outputs, change and self-spends; no owner, entity or sale is inferred. Use local canonical Bitcoin outputs and undo facts with separately admitted creation-UTC-day-start BTC/USD quotes. Historical daily boundaries use retrospective previous-day closes with unknown release time and vintage; hourly and later daily quotes are prospective. Method retains provider credits and price rights; no missing-price fill.
