BTC IV rank, plain English
Implied volatility (IV) is the option market's bet on how violent the next month gets. IV rank tells you where today's IV sits in the 1-year history, 0 to 100. Below 20 is calm, above 80 is panic.

How traders use it
0 to 20
Calm market
Premium is cheap. Long-vol structures (straddles, strangles, calendars) get a discount. Buying protection costs less.
20 to 50
Normal range
Skew matters more than rank here. Watch term structure: contango (back > front) is the typical state.
50 to 80
Elevated
Premium is expensive. Short-vol structures (iron condors, credit spreads) get paid more, but realized often catches up.
80 to 100
Panic / blow-off
Selling premium pays the most but the tail risk is real. This is where 2020-03 / 2022-LUNA / 2024-FTX-aftermath sat.
