Quick answer
Options trading crypto is buying or selling rights (not obligations) on cryptocurrency futures or spot at a strike price by an expiry. Major venues are CME, Deribit, and select exchanges. Four common retail strategies: long call (bullish, capped risk), long put (bearish, capped risk), covered call (income on held coins), and protective put (downside hedge). Implied volatility decides whether options are expensive.
An options contract on a crypto asset gives the buyer the right, but not the obligation, to buy (call) or sell (put) the underlying at a specified strike price by a specified expiry. The buyer pays a premium for that optionality; the seller collects the premium and accepts the obligation. Crypto options markets are smaller than crypto futures markets but they have matured a lot since 2020. Bitcoin options open interest sat in the tens of billions of dollars across major venues by 2024. The math is identical to equity options. The market structure is not.
How are crypto options priced?
Five inputs run an option price (Black-Scholes-Merton or a binomial cousin):
- Spot price of the underlying.
- Strike price.
- Time to expiry.
- Risk-free rate (proxy: short-dated government bill).
- Implied volatility.
The first four are observable. Implied volatility is the market’s bet on how much the underlying will move. Crypto IV typically prints higher than equity IV (BTC at-the-money 30-day IV regularly trades 50-80%, against ~15-25% for the S&P 500). That is the source of both the opportunity and the bleed.
What are the Greeks?
- Delta: how much the option price moves for a $1 change in spot. ATM call ~0.5, ATM put ~-0.5.
- Gamma: how fast delta itself changes. Largest near-the-money and near expiry.
- Theta: time decay. Negative for option buyers (you bleed daily), positive for sellers.
- Vega: sensitivity to a 1-point change in implied volatility. Big numbers on long-dated options.
You do not have to memorise the formulas. You do have to know which Greek is your friend and which is your enemy on every trade you put on.
Four core retail option trades
- Long call. Buy a call. Pay premium. Profit if spot goes up enough to cover premium plus distance to strike. Defined risk (premium), unlimited upside. Theta is your enemy.
- Long put. Buy a put. Hedge or directional short. Defined risk, leveraged downside.
- Covered call. Hold spot, sell a call against it. Generates premium income. Caps upside above the strike. Theta is your friend.
- Cash-secured put. Hold cash, sell a put. Generates premium. If assigned, you buy the underlying at the strike with cash you already had.
What about implied volatility?
IV is the lever. A 30-day BTC at-the-money straddle costs more than its equity equivalent because the market expects bigger moves. Two implications. First, buying options outright is expensive in crypto; theta bleeds fast. Second, sellers of crypto options are paid more for the same risk profile, but the tail risk is also bigger. A weekend exchange exploit or an ETF rumour can move BTC 10% in 30 minutes, blowing past the strike of an at-the-money short call.
What are the leverage rules around crypto options?
In the EEA, retail leverage on crypto via CFDs is capped at 1:2 under ESMA. Crypto options for retail clients are subject to the firm’s product governance and MiFID II appropriateness assessment. Where Volity offers options-style structured exposure, terms are disclosed per product. Professional clients on request may access different conditions subject to MiFID II suitability assessment.
What goes wrong
- Buying short-dated OTM lottery tickets. The expected value is negative for a reason. Lots of zero-premium expirations, occasional jackpots, terrible long-run record.
- Selling naked options without sizing. Premium income looks great until the tail prints. Always size the worst-case loss against account equity.
- Ignoring the term structure. Buying long-dated options when the front month is much cheaper, or selling short-dated when the back month would have collected better premium per unit of risk.
- Confusing notional with risk. A 0.1 BTC option contract sounds small. The IV-driven P&L swing on it can be larger than a 1.0 BTC spot position over the same week.
How to start, sensibly
- Trade defined-risk structures first. Long calls, long puts, vertical spreads. You always know the worst case.
- Size in premium, not in contracts. “I will spend $200 on this call” is the discipline. “I will buy 5 contracts” is the trap.
- Track IV rank, not just price. Buying when IV rank is 80+ is structurally worse than buying when IV rank is 20.
- Close at 50-70% of max profit on credit trades. The last 30% of theta takes too long for the risk left in the trade.
