The Bitcoin Quantile Index (BQI) A single, cycle-agnostic gauge that transforms Bitcoin’s raw, hyper-volatile price into an easily interpretable “temperature” scale from 0 to 100. The bottom pane tracks the BQI through time. The top pane of the chart colors each historical price by its BQI value: greens for cheap, reds for frothy Notice how past cycle peaks align with BQI readings above 90 and bear-market floors sit below 10, signalling that this single line successfully captures Bitcoin’s repetitive boom-bust rhythm without relying on opaque on-chain metrics or macro assumptions.(Sina 🗝️⚡ 21st Capital)
