Crypto Options: Covered Calls and Protective Puts, Explained

The two options strategies a newcomer can actually use — not a full Greeks course — walked through on Deribit and OKX.

Draft status: needs a compliance pass and real product screenshots before it goes live — see the checklist below.

What it is

A call option gives you the right (not the obligation) to buy an asset at a set price (the strike) before a set date (expiry). A put option gives you the right to sell at the strike before expiry. You pay a premium to hold either right, and that premium is the most you can lose as a buyer — which is the opposite risk shape from futures, where losses can exceed your initial margin.

Most crypto options volume happens on two platforms: Deribit, which has historically carried the deepest BTC and ETH options liquidity, and OKX, which offers options alongside its broader derivatives suite.

Why most beginners should skip “buying options” and start here instead

Buying a call or put outright is a directional bet with a built-in time limit — the premium decays as expiry approaches, so you can be right about direction and still lose money if it takes too long to play out. The two strategies below don’t have that problem in the same way, because they’re built around assets you already hold.

Covered call

If you already hold BTC or ETH and don’t expect a big near-term move, you can sell a call option against your holding and collect the premium as income. If the price stays below the strike, you keep the premium and your coins. If it rises above the strike, you’re obligated to sell at the strike price — capping your upside, but you still profit up to that point plus the premium.

Protective put

If you hold BTC or ETH and want downside insurance without selling, you can buy a put option below the current price. If the price falls, the put gains value and offsets your loss. If it doesn’t, you lose only the premium — the same way insurance works: you’re paying for protection you hope not to need.

Walkthrough: selling a covered call on Deribit

Confirm you hold the underlying asset in the amount the contract requires — a covered call assumes you already own what you’d be obligated to sell.
Open the options chain for the asset and expiry date you want, and find a strike above the current price that reflects how much upside you’re comfortable capping.
Sell to open the call at that strike, and confirm the premium you’ll receive.
Track it to expiry. If price stays below the strike, the option expires worthless and you keep both the premium and your coins. If it settles above the strike, your coins are called away at the strike price.

Risk

Selling a covered call caps your upside — if the asset rallies hard past the strike, you miss those gains in exchange for the premium you already collected. Buying a protective put costs a premium whether or not you end up needing the protection. Options pricing and expiry mechanics are more complex than spot or even futures — don’t trade a strategy you can’t explain back in your own words. Nothing on this page is financial advice.
