BTC: Spent Outputs Aged <155 Days — Spent Output Count

Bitcoin Spent Outputs Aged <155 Days — Spent Output Count was 1,055,281 outputs on 7 Nov 2026 (latest daily value).

All spent outputs, for spent inputs under 155 fixed days old.

Why use it. Compare spent-output frequency separately from BTC value and USD marked gain/loss. How to read it. This is a flow count, not the remaining unspent stock. 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); ages below 155×86,400 seconds are younger, including age zero after a header regression. 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 every consumed eligible output once, with known or unknown prices. 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.
