Definition. Beta to BTC (7D) is a 7-day rolling beta coefficient measuring an asset's sensitivity to Bitcoin's price movements, quantifying how much the asset tends to move relative to BTC.

Interpretation. A beta of 1 means the asset moves in line with BTC, values greater than 1 indicate higher volatility relative to BTC (a beta of 1.5 means a 10% BTC move corresponds to roughly a 15% asset move), and values less than 1 indicate lower volatility. Negative beta indicates the asset tends to move opposite to BTC.

This is the Point-in-Time (PiT) variant of Beta to BTC (7D). PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
