Crypto Options on Deribit: BTC and ETH Options Trading

Deribit is the dominant venue for listed crypto options. By a comfortable margin, more BTC and ETH option open interest sits on Deribit than on all other venues combined. For traders who want defined-risk strategies, structured payoffs, and access to the deepest options orderbooks in crypto, Deribit is the practical default. This guide covers the contract specs, the pricing conventions, and the strategies that work on the platform.

Why Deribit

The platform launched in 2016 and built early dominance in crypto options when most exchanges focused exclusively on perpetuals and spot. Today Deribit's BTC option open interest typically runs 70-80% of the global total, with ETH options similarly concentrated. Liquidity drives liquidity, institutional flow, market makers, and retail all converge on the same venue.

OKX and Bybit have grown crypto options books but remain distant followers in volume and strike depth. CME offers BTC and ETH options for US-regulated access but with very different specs and a smaller liquidity profile. For global traders looking for breadth, Deribit is the default.

Contract specifications

Underlying and expiries

• Underlyings: BTC, ETH, SOL (smaller book), and a handful of other large-cap tokens.
• Expiries: Daily, weekly, monthly, quarterly. The June and December expiries each year are the deepest, used by institutional hedgers as benchmark strikes.
• Style: European, exercisable only at expiry.
• Settlement: Cash-settled in the underlying coin (e.g., BTC options settle in BTC). USDC-margined options also exist for traders who prefer dollar-denominated PnL.

Strikes

Strikes are quoted in USD terms but settled in coin terms (for BTC/ETH options). Strike spacing widens for further-out-of-the-money options and tightens around the at-the-money region. Custom strikes are not available, you trade what is listed.

Tick size and minimum trade

Tick sizes vary by underlying and moneyness. Minimum trade size is 0.1 BTC or 1 ETH for most contracts. Block trade facilities exist for larger institutional fills.

Pricing conventions

Deribit prices BTC options in BTC terms, a quirk that confuses newcomers. A call option on BTC at $65,000 strike might be quoted at 0.0250 BTC. To convert to USD: 0.0250 × $65,000 = $1,625 per BTC of underlying.

Implied volatility is the universal language of options pricing. Deribit publishes the DVOL index (BTC implied volatility, similar in concept to the VIX) and the orderbook displays IV alongside price. Reading IV first and price second is the right habit.

Common strategies

Long calls and long puts

The simplest options trade: pay premium, get unlimited upside (calls) or downside protection (puts). Maximum loss = premium paid. Useful for high-conviction directional views with defined risk. Premium decay (theta) eats into the position daily.

Covered call

Hold spot BTC, sell an out-of-the-money call against it. Generates income (the call premium) and caps upside at the strike. The classic income strategy for traders who hold BTC long term and accept giving up upside above a chosen level.

Protective put

Hold spot BTC, buy an out-of-the-money put. Insurance against drawdowns. Cost = the put premium. Combine with a covered call for a "collar", capped upside, capped downside.

Straddle and strangle

Buy a call and a put at the same expiry. The straddle uses the same strike (typically at-the-money); the strangle uses different strikes (out-of-the-money on both sides). Profits from large moves in either direction. Loses if the underlying drifts sideways. Often used around binary catalysts (ETF decisions, major macro events).

Iron condor

Sell an out-of-the-money call spread and an out-of-the-money put spread. Defined-risk income strategy. Profits if the underlying stays within a range. Maximum loss occurs if the underlying breaks through either short strike.

Calendar spread

Sell near-term option, buy longer-term option at the same strike. Profits from time decay differential. Common when implied volatility is term-structured (near-term IV elevated relative to longer-term IV).

For a worked example of a binary-event play, see BTC options straddle strategy.

The Greeks

Deribit displays Greeks in real time on every contract. The five that matter:

• Delta, change in option price per $1 move in underlying. Long calls have delta 0 to 1; long puts have delta -1 to 0.
• Gamma, rate of change of delta. Highest at-the-money, particularly for short-dated options.
• Vega, sensitivity to implied volatility. Long options are long vega; short options are short vega.
• Theta, time decay. Long options bleed theta daily; short options collect theta.
• Rho, sensitivity to interest rates. Less material in crypto than in traditional rates products.

Margin and collateral

Deribit offers two margin modes for options:

• Standard margin, collateral required for short positions calculated per leg, generally conservative.
• Portfolio margin, collateral calculated on the net risk of the entire portfolio. A delta-hedged options book requires far less margin under portfolio mode. Eligibility requires a minimum equity threshold and an opt-in.

Collateral can be posted in BTC, ETH, USDC (and a few other supported assets). USDC-margined options simplify dollar-denominated PnL accounting but lose the natural hedge of coin-margined exposure.

Cost structure

Deribit fees are competitive. Maker rebates apply on most products; taker fees range from 0.03% to 0.04% of underlying notional depending on the product. Settlement fees apply at expiry. Block trades have separate fee schedules.

Risks specific to options

• Pin risk at expiry, at-the-money options at expiry can settle either side of the strike with material PnL implications. Close expiring positions before settlement to remove this risk.
• Volatility crush, short option positions lose if implied volatility spikes unexpectedly. Most painful for naked short calls or puts.
• Liquidity risk, far out-of-the-money strikes and far-dated expiries have wider spreads. Avoid market orders on illiquid contracts.

Practical access

Account opening on Deribit requires KYC for most jurisdictions. The platform serves users globally except for restricted regions (US persons most notably, plus a sanctions-driven exclusion list). For European, UK, South African, Brazilian, and other international traders, access is straightforward.

API access is mature, with REST and WebSocket endpoints used heavily by market makers and quant traders.
