Crypto options are derivative contracts that give a trader the right, but not the obligation, to buy or sell an asset at a set price by a set date, and they evolved from a fragmented, illiquid corner of the market before 2019 into a multi-billion dollar segment once exchanges like Deribit built proper risk infrastructure around them.
Before options had real liquidity
Prior to 2019, crypto derivatives activity was concentrated almost entirely in spot margin trading and perpetual futures. Options existed but traded in small, custom over-the-counter deals with wide spreads and little standardization. Deribit changed that by introducing European-style, cash-settled options alongside a real-time portfolio margin system and a dynamic risk engine, which made it practical for market makers to quote tighter prices at meaningful size.
How growing open interest started to move spot
As total options open interest pushed past $1 billion, the market makers on the other side of those trades began actively hedging their exposure, known as gamma, in the spot and perpetual futures markets. That hedging activity produced a new observable pattern: spot price would drift toward the strike prices with the heaviest open interest as monthly expiration approached, an effect traders started calling pinning.
What this means for a trader today
Tracking Deribit's total open interest gives a rough read on how much institutional capital is positioned in options at any given time, and unusually large concentrations near a monthly expiration can hint at reduced volatility in the days beforehand as pinning effects take hold. Comparing implied volatility against recent realized (historical) volatility, often summarized as IV rank, also helps determine whether option premiums currently look expensive or cheap relative to how the underlying has actually been moving.
