BTC: UTXOs Aged <155 Days — Supply with Known Creation Price

Bitcoin UTXOs Aged <155 Days — Supply with Known Creation Price was 3,843,790.84 BTC on 7 Nov 2026 (latest daily value).

BTC value with an admitted creation-day basis for spendable outputs under 155 fixed days old.

Why use it. Compare how much of the stock can be valued from known creation prices. How to read it. This is value-weighted coverage, not a holder or output count. A zero known value can coexist with zero-valued priced outputs or positive unknown BTC. Use exact creation-header age at that snapshot: older means creation time at or before its header time minus 155×86,400 seconds; later or future-dated creations are younger. Header regressions are retained; request time does not age the stock. Read unknown-price BTC and price coverage alongside the result. Unobserved history stays unknown; genuine source/price holds and partial/provisional/final labels remain in force.

Calculation. Sum known-basis unspent satoshis and divide by 100,000,000. The spendable snapshot follows the highest canonical block assigned to the UTC period, including eligible coinbase/change but excluding genesis, provably unspendable outputs and BIP30 overwrite losses. Use local canonical Bitcoin outputs and undo facts with separately admitted creation-day-start BTC/USD quotes. Historical daily boundaries use retrospective previous-day closes with unknown release time and vintage; hourly quotes use recorded prospective observations. Method retains provider credits and price rights. Missing prices are never filled.
