One number, 0–100, answering a single question: how hot is Bitcoin today? Higher = hotter. It is weather, never advice: Hot is not "buy" and Cold is not "sell" — they are descriptions of market temperature.
Weighted average of six 0–100 components. Same inputs → same score, forever reproducible. No editorial thumb on the scale, no sponsor can touch it.
Momentum (30). Where the price sits versus its own 50-day and 200-day averages. Above both = hot, below both = cold.
Sentiment (20). The Fear & Greed index, taken as-is. Crowd psychology, measured daily.
Distance from the top (15). How close price is to its all-time high. At the high = 100; at −80% = 0.
Leverage heat (15). The funding rate of perpetual futures: when longs pay a lot to stay long, the market is running hot.
Volatility (10). How wild the last 30 days were, compared with the past year. Wild = hot.
Network congestion (10). Mempool fees on a log scale: 1 sat/vB = quiet, 200 = frenzy.
Data sources: exchange market data, alternative.me, mempool.space. The score recomputes once a day at 07:00 UTC — one number a day, on purpose. Today's component values are in the app; the machine-readable formula lives at /api/formula.
Educational tool. The score describes market conditions; it is not a signal, a prediction, or financial advice.
