How to read it
Realized volatility is the annualized standard deviation of log-returns over a trailing window: σ_ann = std(log(p_t / p_(t-1))) · √365.
BTC's realized vol has trended lower across cycles - the 365-day series tells the long story. Short-window (30d) vol spikes around macro news and cycle turning points; the 365-day baseline keeps slowly compressing as adoption deepens.
