Live S2F ratio and PlanB model price versus actual BTC price. Updated every 15 minutes. For educational purposes only — not financial advice.
Each halving doubles the S2F ratio, roughly quadrupling the model's predicted price. The model overshot significantly in H4 — the table shows the divergence between model prediction and the actual cycle peak.
Stock-to-Flow divides Bitcoin's circulating supply (the “stock”) by the annual new issuance rate (the “flow”). After each halving, the flow is cut in half — doubling the S2F ratio and significantly increasing the model's predicted fair value.
The model price uses PlanB's original power-law formula: price = e^(−1.84) × S2F^3.36. Circulating supply is sourced from blockchain.info; price from Binance public API. Data refreshes every 15 minutes.
The Brief covers S2F context, cycle phase, on-chain signals, and regime change alerts — weekly, systematic, no noise.
