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.
