The 7-day rolling beta coefficient measuring the asset's sensitivity to Bitcoin's price movements. Beta quantifies how much the asset tends to move relative to BTC.

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