BTC: Spent Outputs Aged ≥155 Days — Spent Value at Cost — Known Prices

Bitcoin Spent Outputs Aged ≥155 Days — Spent Value at Cost — Known Prices was 0 BTC on 7 Nov 2026 (latest daily value).

Original spent BTC whose period-start quote is exactly equal to its creation-day basis, for spent inputs at least 155 fixed days old.

Why use it. Compare consumed value above, below or equal to its recorded basis without confusing BTC volume with USD gain/loss. How to read it. Both quoted prices are required. Zero selected BTC can mean an empty class or that the value has unknown prices; read excluded BTC coverage. This is not realized USD profit/loss or evidence of a sale. 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. Compare admitted period-start disposal price directly with creation-day basis, sum the selected original satoshis and divide by 100,000,000. Strict inequalities select profit/loss; exact equality selects at cost. 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.
