BTC: Stock-to-Flow — Trailing 30-Day Actual Issuance

Bitcoin Stock-to-Flow — Trailing 30-Day Actual Issuance was 118.75 years on 7 Nov 2026 (latest daily value).

Cumulative actual issuance divided by annualized trailing 30-day actual issuance.

Why use it. Compare cumulative issued stock with a stated recent issuance pace. How to read it. This is an original issuance statistic, not a price prediction or a count of spendable coins. Cumulative issuance includes genesis and subsequently lost coins. All 30 daily issuance inputs are required; missing history leaves a gap, and partial inputs retain partial finality. A zero issuance denominator is undefined; signed actual issuance can produce a negative ratio.

Calculation. Use local canonical coinbase value minus exact fees for actual issuance. Sum the trailing 30 daily issuance observations and annualize by multiplying by 365/30. Divide the same day's cumulative actual issuance by that denominator using 40-digit Decimal arithmetic. Proved empty days contribute zero issuance; no scheduled-subsidy estimate or price input replaces actual claimed rewards.
