30-day realized volatility

Each point is the annualized standard deviation of the prior 30 daily log-returns — the standard “how bumpy has it been” gauge. Long arc: Bitcoin's volatility has trended down as it matured, but still spikes around big moves.

How to read this

Bitcoin's realized volatility — how much its daily price actually moved — over time, computed from our own daily closing prices.

We take daily log-returns, roll a standard deviation over a 30- (or 90-) day window, and annualize it (×√365). The result is a percentage: roughly the one-standard-deviation yearly swing implied by recent daily moves.
Realized = backward-looking (what actually happened), unlike implied volatility from options (what the market expects).
The percentile says where today’s 30-day reading sits within its whole history — low = unusually calm, high = unusually wild.
Volatility cuts both ways: it’s the size of the moves, not the direction. High vol means big up AND down days.
