What is crypto implied volatility?
Implied volatility is the market's estimate of how much a coin will move, read from option prices. High IV means big swings are expected, so every option, call and put, costs more. Low IV means calm is expected and options are cheap. Buyers prefer to buy when IV is low; sellers prefer to sell when it is high.

The price of uncertainty
Volatility is how much the market is expected to move. High volatility means big swings are likely, so every option, call and put, costs more.
Drag the volatility slider. With the price flat, a bought option rises in value when volatility rises, and falls when the market calms down.
Think of it like this. Insurance costs more in monsoon. Same bike, same cover, more risk of a claim.

Questions people ask
What is a good implied volatility for Bitcoin?
There is no fixed good number. Compare IV with its own recent range: Algoclear's Market now shows the IV rank, where today's IV sits within that range.
Why do crypto options get expensive before big events?
Because the market expects a big move, so implied volatility rises. After the event, IV often drops quickly, and option prices fall with it even if Bitcoin did not move.
Does high IV mean Bitcoin will go up?
No. IV measures the size of the expected move, not its direction. A high IV makes both calls and puts expensive.
How IV sets crypto option prices
An option's price depends on the price of the coin, the strike, the time left and one number nobody can see directly: how much the coin will move. Implied volatility is that number, worked backwards from the prices traders are paying.
On Delta Exchange India, every Bitcoin and Ethereum option carries its implied volatility, shown as IV on the option chain.
Why crypto volatility runs higher
Bitcoin trades around the clock, reacts to global news at any hour and has no circuit breakers. Its implied volatility usually sits well above a stock index's, so crypto options pay sellers more and cost buyers more for the same distance from the price.
Implied versus realised volatility
Realised volatility is what actually happened. When implied volatility is above realised, options are expensive relative to the movement, which favours sellers. When it is below, options are cheap, which favours buyers. Market now shows both for BTC, ETH and Gold.
