Bitcoin AI
Stock-to-flow — Bitcoin AI can explain the scarcity model and its limits.
Today
Stock-to-flow
Compares circulating supply to annual issuance — scarcity rises after each halving.
Halving epochs
PlanB’s stepped model price updates at each epoch; the orange dashed line is the model path.
Log scale
Price, 200W MA, and model share a logarithmic Y-axis for long-run context.
Halving colours
Daily dots coloured by days until the next halving (blue near halving, red early cycle).
Not a forecast
Educational overlay only — spot can diverge from the model for years.
Snapshot & history
Live distances to today’s bull and bear envelopes, how long spot has stayed in the current zone, and where price has spent time vs this log model since daily data begins.

Frequently asked questions
S2F relates existing supply (stock) to new issuance (flow). Bitcoin’s halving schedule makes ‘flow’ shrink over time, which the model maps to scarcity narratives.
