Methodology

Open, reproducible — computed from our own archive node

Definition

Percentage of circulating supply held by short-term holders — coins younger than 155 days.

Formula

pct_sth = sth_supply_btc / total_supply_btc

How we compute it

We track STH/LTH supply with a stock-and-flow model: each day, newly-minted coins enter STH; coins crossing the 155-day threshold age into LTH; per-cohort spends reduce the relevant bucket. STH supply is the residual (total − LTH).

Provenance · Every on-chain metric traces back to our own self-hosted Bitcoin archive node — no third-party data vendor sits in the path. We extract the full UTXO lifecycle (each output's creation height/time, value, and the height/time it was later spent), join it against an independent USD price oracle, and roll it up into daily aggregates. The metric formulas are pure functions over those aggregates (src/pipeline/formulas.py), so any value on this page can be reproduced from the published daily archive.

Interpretation

High % STH = lots of recently-acquired, weak-handed supply (speculative, top-heavy). Low % STH = supply is maturing into long-term hands (accumulation).

Caveats & limitations

  • ·The 155-day STH/LTH split is the industry convention, not a behavioural certainty. The stock-and-flow ageing relies on accurate per-cohort spent flows; days with sparse cohort data fall back to aggregate spends.

Current % STH reading

As of 2026-10-16, Bitcoin’s % STH is 18.5%, compared with 24.0% one year earlier (2025-10-16). The series has 6,490 daily readings from 2009-01-09 to 2026-10-16, computed from our own full-archive Bitcoin node and refreshed every day.

Historical extremes

The highest % STH on record is 100.0% on 2009-01-09; the lowest is 16.1% on 2026-07-26. Readings near either end of that range have historically coincided with cycle turning points — use the chart above to see where today sits relative to past extremes.
