Crypto Options Basics: Calls, Puts, and the One Strategy That Actually Pays Retail

Options are contracts giving the buyer the right (but not obligation) to buy or sell an asset at a specific price by a specific date. They're the most flexible derivative, capable of expressing complex views with defined risk. They're also one of the easiest places to lose money fast for retail. This chapter covers the basics: what the contracts are, how they're priced, and which strategies actually have edge for retail vs which are sucker bets.

The two basic contracts

Call option. Right to buy the asset at the strike price by the expiration date. You buy a call if you think the price will rise above the strike before expiration. You profit when the asset price exceeds strike + premium paid.

Put option. Right to sell the asset at the strike price by the expiration date. You buy a put if you think the price will fall below the strike before expiration. You profit when the asset price falls below strike - premium paid.

For each option, you can be the buyer or the seller.

Buyer (long option): pays the premium up front. Limited risk (the premium). Can profit if the price moves favorably. Loses the entire premium if the option expires worthless.

Seller (short option): receives the premium up front. Has obligation to honor the option if the buyer exercises. Profit limited to the premium; loss potentially large (if buyer's option becomes very valuable).

The asymmetry: option buyers have limited downside, unlimited upside. Option sellers have limited upside (the premium), potentially large downside. This shapes which strategies make sense for which participant.

Where crypto options trade

The dominant venue: Deribit (BTC and ETH options; ~85%+ of crypto options volume). Smaller venues include OKX, Bit.com, ByBit. CME also offers BTC and ETH options for institutional players.

Most crypto options:

• Inverse-settled (settled in BTC for BTC options)
• European-style (can only be exercised at expiration)
• Cash-settled (no actual asset transfer; PnL paid in the settlement currency)
• Limited expiration dates (weekly, biweekly, monthly, quarterly)

If you've traded equity options, crypto options are similar in concept but differ in settlement, exercise, and venue specifics. Read the contract specifications carefully.

Option pricing, the basic intuition

Option premiums depend on:

1. Intrinsic value. For a call: max(0, current_price - strike). For a put: max(0, strike - current_price). The "in-the-money" value the option already has.

2. Time value. The probability that the option becomes more valuable before expiration. Decays as expiration approaches. "Time decay" or "theta."

3. Volatility. Higher expected volatility = higher option premium. Implied volatility (IV) is the market's expectation of future volatility, derived from the option's price.

4. Interest rates. Affect option pricing through carry calculations. Less material in crypto than in traditional finance.

5. Time to expiration. Longer expirations have more time value. Decay accelerates as expiration approaches.

The Black-Scholes formula combines these into option prices. You don't need to compute it manually, exchanges show the prices. But understanding what moves them helps you interpret what you're paying.

Why most retail loses on options

Several structural reasons:

1. Time decay against the buyer. Every day that passes reduces the option's value (for the buyer). Even if your directional view is correct, if it doesn't play out fast enough, time decay erases your gains.

2. Implied volatility tends to be expensive. Option premiums often price in higher volatility than actually realizes. The buyer pays for expected volatility; the seller captures the difference between expected and realized.

3. Premiums look small but are leveraged. A "$200 call premium on BTC at $66,000" sounds cheap. But the premium represents a leveraged position. Lose the premium and you lose 100% of the capital deployed.

4. Multiple things have to go right. Direction, magnitude, timing, all three need to favor the option buyer for a profitable trade. The spot trader only needs direction.

5. Bid-ask spreads on options can be wide. Especially for less-liquid strikes and expirations. Round-trip costs can be substantial.

The math: for the option buyer to profit, the underlying move needs to be larger than what the market has already priced in (via the IV). On average, the market prices it correctly, meaning the option buyer's expected return is roughly negative after fees.

This is why most retail option-buying strategies underperform. The strategy isn't capturing edge, it's paying for the privilege of leverage with defined downside.

Strategies retail might consider

1. Covered calls. You own spot. You sell call options against the spot. You collect the premium. If the call expires worthless, you keep both spot and premium. If the call gets assigned, you sell your spot at the strike price (which caps your upside but you got the premium).

The strategy: cap upside in exchange for steady income. Works well in sideways or modestly-rising markets. Underperforms in strongly trending markets (your spot gets called away below where it would have ended).

A reasonable retail strategy if:

• You have spot exposure you'd be willing to sell at a specific level anyway
• You can tolerate "missing out" on strong rallies for the income
• You manage the strikes and expirations consistently

2. Cash-secured puts. You hold cash. You sell put options at a strike where you'd be happy to buy the asset. You collect the premium. If the put expires worthless, you keep cash and premium. If the put gets assigned, you buy the asset at the strike price (effectively a "limit buy" that pays you to wait).

The strategy: get paid to wait at a target entry level. Works well when you have a target entry below current price.

A reasonable retail strategy if:

• You have a specific target entry for the asset
• You're committed to actually buying at that level
• You have the cash to back the put if assigned

3. Hedging with puts. You own spot. You buy puts as insurance. The puts appreciate if the price falls, offsetting losses.

Useful in specific situations (e.g., you don't want to sell but want downside protection through a known event). Not a profit strategy, an insurance cost.

Strategies retail should mostly avoid:

Buying calls speculatively. "I think BTC will rip; I'll buy calls." Math is mostly negative-EV because of time decay and expensive IV. The "leveraged upside" doesn't come without cost.

Naked short calls. Selling calls without spot to back them. Theoretically unlimited loss if the asset rallies hard. Catastrophic risk profile.

Complex multi-leg strategies (spreads, butterflies, condors) without deep understanding. These have specific use cases but require precise execution. Most retail doesn't manage them well.

A common mistake: chasing IV spikes by buying

A trader sees IV spike before a known event (FOMC, ETF decision). They buy options expecting volatility. The event passes; IV crushes back to normal. Their option loses value even though the underlying move was as expected.

The fix: high IV means options are expensive. Buying into IV spikes is expensive. Selling into IV spikes captures the eventual IV crush, but requires risk management. Don't naively buy options when IV is already high.

A common mistake: short-dated speculation

A trader buys 0DTE (zero days to expiration) options hoping for a same-day move. The options have most of their value tied to time; even with a correct direction, the time decay over hours can erase the gains.

The fix: 0DTE options are casino chips, not trading instruments. The expected value is roughly negative for buyers across many trades. If you do them recreationally, treat them as entertainment, not trading.

A common mistake: not understanding inverse settlement

Crypto options on Deribit are typically inverse-settled (settled in BTC for BTC options). The PnL math is non-linear in BTC terms because the value of BTC itself moves. New traders often miscalculate their risk by thinking in dollar terms when the contract settles in BTC.

The fix: read the contract specifications carefully. Practice with small positions before scaling. Use exchange-provided risk calculators.

A common mistake: confusing options with leverage

Options provide a form of leverage (you control more notional than the premium suggests). But they're fundamentally different from perpetual leverage:

• Options have time decay
• Options have IV exposure
• Options have defined max loss (for buyers)
• Options have defined or unlimited max loss (for sellers, depending on strategy)

Treating options like "leverage with insurance" misses the time and volatility dimensions that make options behave very differently from perps.

Mental model, options as insurance contracts

An insurance contract: you pay a small premium to protect against a specific outcome over a specific period. If the outcome happens, the insurance pays out. If it doesn't, the premium is gone.

Options are the same structure. A call is "insurance that the price will rise." A put is "insurance that the price will fall." Sellers are the insurance companies, collecting premiums from many buyers, paying out on the few that exercise.

Insurance is profitable for the insurer (in aggregate) because they price the risk correctly. The buyer's expected outcome is slightly negative (they pay more in premium than they receive in payouts on average), but they accept that for the protection.

For retail trading: options as protection (puts on positions you hold) is conceptually clean. Options as speculation (buying calls on a directional view) suffers from being on the buyer side of a structurally expensive product.

Why this matters for trading

Options are useful in specific situations (covered calls on spot, cash-secured puts, hedging known events) and traps in others (speculative call buying, 0DTE casino chips, naked shorts). Understanding the basics tells you which is which. Hex37's primary focus is spot and perpetual trading; options trading typically happens on dedicated venues like Deribit. Knowing the options landscape complements your primary trading even if you don't actively trade them.

Takeaway

Options give the buyer the right to buy (call) or sell (put) at a specific price by a specific date. Buyers have limited downside, unlimited upside, but pay premium and time decay. Sellers receive premium but have limited upside, potentially large downside. Most retail option-buying strategies are structurally negative-EV due to time decay and expensive IV. Reasonable retail strategies: covered calls, cash- secured puts, event-hedging puts. Avoid: speculative call buying, naked shorts, complex multi-leg without understanding, 0DTE casino chips. Treat options as insurance contracts, not as "leverage with safety net."
