A covered call lets you earn income on Bitcoin you already hold by selling a call option against it. You collect a premium upfront in exchange for capping your upside above a chosen strike price. It is the most popular income strategy in options, and crypto's higher volatility makes the premiums richer than anything in equities.
This is article eight in our series on crypto options trading. The previous two articles covered buying options: buying a call for a bullish view and buying a put for protection. Now we flip to the other side of the trade. Instead of paying a premium, you collect one. If you are brand new to options, start with what crypto options actually are first.
TL;DR
A covered call means selling a call option against an asset you already own, collecting a premium as income
It is a neutral to mildly bullish strategy: best when the asset stays flat or rises modestly, worst in a sharp rally where your upside is capped
Your income is the premium. Crypto premiums are richer than equity premiums because crypto is more volatile
The trade-off is capped upside above the strike. You still carry full downside on the asset, cushioned only by the premium collected
On Paradex you can sell BTC covered calls against spot or perps in one unified margin account, with low fees
What is a covered call?
A covered call is an options strategy where you sell a call option against an asset you already own. You collect a premium upfront in exchange for agreeing to sell the asset at a fixed strike price if it rises to that level by expiry. The position is "covered" because you hold the underlying asset, so if the call is exercised, you simply deliver what you already have. There is no scramble to buy at a higher price.
This is the defining difference from the trades in the previous two articles. When you buy a call, you pay a premium for the right to profit from a rise. When you sell a covered call, you are on the other side. You receive the premium, and in return you take on the obligation to sell if the buyer exercises. You are no longer paying for optionality. You are getting paid to provide it.
A covered call has two ingredients working together: a long position in the underlying asset (your BTC), and a short call sold against it. The long asset gives you exposure to price. The short call generates income and caps how much of an upside move you keep. Combined, they produce a position that earns yield in flat and modestly rising markets, in exchange for giving up the explosive upside of a sharp rally.
New to the mechanics? A call option gives its buyer the right to buy an asset at the strike. As the seller of that call, you have the matching obligation to sell. For the full grounding, read what crypto options actually are and how to read an options chain.
How does a covered call work?
The cleanest way to understand a covered call is to watch it resolve at every possible price. Here is the setup we will use throughout this article.
Covered call P&L at expiry. Hold 1 BTC at $90K, sell a $100K call for $2.5K. Profit caps at $12.5K above the strike; the premium lifts the whole curve above spot-only.
Worked example
Setup: You hold 1 BTC, currently worth $90,000. You sell one call option with a strike of $100,000 expiring in one month. You collect a premium of $2,500 immediately.
Scenario A (BTC stays flat at $90,000): The call expires worthless. You keep your BTC and the full $2,500 premium. That is a 2.78% return on the position in one month, earned while simply holding.
Scenario B (BTC rises to $100,000 or above): Your BTC is sold at the $100,000 strike. You capture the $10,000 gain from $90,000 to $100,000, plus the $2,500 premium, for a maximum profit of $12,500. If BTC rockets to $130,000, you still only make $12,500. That forgone upside is the cost of the strategy.
Scenario C (BTC falls to $80,000): Your BTC has lost $10,000 in value, but you keep the $2,500 premium, so your net loss is $7,500 instead of $10,000. The premium cushioned the fall. Your downside breakeven is $90,000 minus $2,500, or $87,500.
Notice the shape of the outcome. In a flat or modestly rising market, the covered call beats simply holding by the amount of the premium. In a sharp rally, it underperforms because the upside is capped. In a decline, it loses less than holding alone. This is why a covered call is described as a neutral to mildly bullish strategy. It monetises the most common market condition, sideways-to-up, and accepts a cap on the rarest and most explosive one.
Why sell covered calls to earn yield on crypto?
Most people hold BTC and do nothing with it while they wait. A covered call turns that idle holding into a yield-generating position. Every premium you collect is income on an asset you were going to hold anyway. For a long-term holder with a neutral short-term view, this is one of the few ways to be paid for patience.
Crypto premiums are richer than equity premiums. Option premiums scale with implied volatility, and crypto is structurally more volatile than the stock market. The same strategy that yields a modest premium on a blue-chip stock collects a meaningfully larger one on BTC. The volatility that makes crypto nerve-wracking to hold is the very thing that makes selling calls against it lucrative.
The honest framing matters here. A single month's premium is not an annual yield. If you collect roughly 2 to 4 percent in premium on a one-month call, that is income for the month, repeatable only if you sell a new call each cycle, and never guaranteed. Some months the call gets exercised and you part with your BTC at the strike. Some months a sharp rally leaves you wishing you had simply held. The covered call is a discipline, not a free lunch, and it rewards a holder who is genuinely comfortable selling at the strike they chose.
Want the strategy without managing the trades? A covered-call vault runs this exact strategy systematically on your behalf, selling calls each cycle and distributing the yield. Read how tokenised strategy vaults work in our piece on Vault Traded Funds (VTFs), DeFi's on-chain answer to the ETF.
How do you sell a covered call step by step?
Here is how to place a covered call on BTC, in order, from holding the underlying to compounding the yield over time.
1Hold or open the underlying BTC position. Make sure you hold the BTC you intend to cover, either as spot or as a long perpetual position, in your account. The covered call is sold against this holding.
2Open the BTC options chain at app.paradex.trade/options/BTC. Connect your wallet and switch the chain view to calls.
3Select your expiry. Shorter expiries (one to four weeks) let you collect premium more frequently and the time decay works in your favour as the seller. Longer expiries collect a larger premium up front but tie up the position for longer.
4Choose a strike above the current price. Pick a strike you would genuinely be willing to sell BTC at. A strike 5 to 15 percent above spot balances a meaningful premium against retained upside. The closer to spot, the bigger the premium but the tighter the cap.
5Check the bid price and implied volatility. As the seller you receive the bid. Higher IV means a richer premium, so elevated IV is the seller's friend. (For why IV drives premium, see how options are priced.)
6Calculate your key levels. Premium received is your income and your downside cushion. Maximum profit equals the premium plus the gain from spot up to the strike. Downside breakeven equals your entry price minus the premium. Write these down before placing the order.
7Sell the call. Select the call at your chosen strike and expiry. Set direction to sell. Enter the quantity matching your underlying holding. Review the order: direction sell, type call, strike, expiry, premium received. Confirm.
8Use the payoff chart. On Paradex the payoff chart shows the combined outcome of your underlying position plus the short call at every BTC price at expiry, making the capped upside and premium cushion immediately visible.
9Manage toward expiry. If BTC stays below the strike, let the call expire worthless and keep the premium. If BTC approaches or exceeds the strike and you want to keep your BTC, roll the call up and out to a higher strike and later expiry.
10Repeat to compound the yield. Income from a covered call is earned per cycle. To turn it into an ongoing yield, sell a new call each period. Decide your strike-selection rule in advance so the process stays disciplined rather than emotional.
What are the risks of selling covered calls?
A covered call is one of the lower-risk options strategies, but "lower risk" is not "no risk." There are three things every seller must understand before placing the trade.
Capped upside is the real cost. This is the risk that actually bites. If BTC rips through your strike, your gains stop at the strike while a simple holder rides the whole move. The $2,500 premium feels small consolation when BTC has run $30,000 past your cap. You did not lose money in absolute terms, but you left a great deal on the table. This is "opportunity cost," and in a bull market it is painful. Only sell calls at strikes you are genuinely content to sell at.
You still carry full downside on the asset. The covered call does not protect your BTC from a crash. If BTC falls 40 percent, your spot position falls with it, and the premium offsets only a sliver of that. A covered call is an income strategy, not a hedge. If downside protection is what you want, that is a protective put, not a covered call. Some traders combine both into a structure called a collar, which we cover later in this series.
Assignment can happen early in some cases. On Paradex, options are European style and settle only at expiry, which removes the early-assignment surprise that American-style equity options carry. Even so, you should always be prepared for the call to be exercised at expiry if BTC closes above the strike. Plan for it. If you would be upset to sell your BTC at the strike, the strike is too low.
The key insight on risk: a covered call never loses more than holding the asset alone would. In every single scenario, the covered call position is worth exactly the premium more than an uncovered holding. The "risk" of a covered call is not a loss you would not otherwise have taken. It is a gain you agree to forgo in exchange for guaranteed income today.
How does a covered call compare to other income and hedging strategies?
The covered call sits in a family of strategies that involve selling options or protecting positions. Knowing where it fits prevents the most common beginner mistake: using a covered call when a different tool was the right one.

Main trade-off
Covered call
Sell a call against BTC you own

Sell a put while holding stablecoin to buy if assigned
Getting paid to wait for a lower entry price on BTC you want to own
The cleanest mental model: a covered call and a protective put are opposites. One sells upside to earn income; the other spends income to buy protection. A cash secured put is the covered call's mirror image, applied to cash you want to deploy rather than an asset you already hold. Combine a covered call with a protective put and you have a collar, the subject of a later article in this series.

How do you trade covered calls on crypto with Paradex?
Paradex is an on-chain venue for crypto options, perpetual futures, and spot, all from one self-custodial account. It is built by the team behind Paradigm, the largest institutional options liquidity network in crypto, and that institutional flow feeds the order book directly. For a covered-call seller, deep liquidity matters: it means your call sells at a competitive premium rather than sitting in a thin book at a price nobody will pay.
What makes Paradex particularly suited to selling covered calls:
Unified margin. Your spot BTC, perpetual positions, and options live in one account, so the BTC you hold can directly collateralise the call you sell. No moving assets between venues to cover the position.
A flat 0.0075% options fee, capped at 12.5% of the premium for retail accounts. Fees eat directly into option-selling income, so keeping them low means more of every premium stays with you. See the trading fees documentation.
Self-custody throughout. You connect a wallet. Your BTC never leaves your control, even while it backs an open call.
European-style settlement at expiry, which removes the early-assignment uncertainty of American-style equity options and makes the strategy easier to manage.
Position privacy via ZK technology, so your strikes and size are not visible to other traders on the book.
Built on Paradex Chain (StarkNet L2) for on-chain settlement at competitive execution speed, incubated by Paradigm.
The chart below shows why the strategy is attractive for a holder. Across the most common market outcomes, flat and modestly up, the covered call sits above the spot-only line by the full premium. You only give ground in a sharp rally past the strike.
The yield pickup. Below the strike, the covered call sits above spot-only by the full premium. Above the strike, you trade further upside for the income already banked.
For traders in India, Singapore, the UK, Brazil, and other global markets, the experience is identical: connect a wallet, open the BTC options chain, and sell a call against the BTC you hold. You can also hold idle stablecoin in Paradex vaults or run the underlying as a perpetual position, all from the same account. For live volume and open interest, see paradex.trade/stats; for the full mechanics, the documentation covers margining and settlement end to end.
What is the one thing to remember?
Only sell a covered call at a strike you would genuinely be happy to sell at. Every other detail follows from this. If you treat the strike as a price you are content to part with your BTC for, then every outcome is acceptable: BTC stays flat and you keep the premium, or BTC rises to the strike and you sell at a price you already chose, with the premium on top.
The covered call rewards the holder who is honest with themselves about their view. If you are secretly convinced BTC is about to double, do not sell calls against it; just hold. But if your real view is that BTC will drift sideways or grind higher over the next month, the covered call pays you for exactly that view. It is the income strategy for the patient, the neutral, and the disciplined. Choose the strike with intention, collect the premium, and repeat.
Frequently asked questions
A covered call is an options strategy where you sell a call option against an asset you already own. You collect a premium upfront in exchange for agreeing to sell the asset at a fixed strike price if it rises to that level by expiry. The position is covered because you hold the underlying asset, so if the call is exercised you simply deliver what you already have. It generates income on a holding in exchange for capping your upside above the strike.
You hold an asset such as 1 BTC and sell one call option against it at a strike above the current price. You receive the premium immediately. If BTC stays below the strike at expiry, the call expires worthless and you keep both your BTC and the premium. If BTC rises above the strike, your BTC is effectively sold at the strike price; you keep the premium plus the gain up to the strike, but you forgo any upside beyond it.
Yes. On Paradex you can sell covered calls on BTC against spot or perpetual positions held in the same self-custodial account. Because options, perpetuals, and spot share one unified margin account, the asset you hold can collateralise the call you sell, all on Paradex Chain (StarkNet L2). Options trade at a flat 0.0075% fee, capped at 12.5% of the premium.
The income equals the premium collected, which depends on the strike, the time to expiry, and implied volatility. Crypto premiums are typically richer than equity premiums because crypto is more volatile. As an illustration, a one-month call on 1 BTC at a strike roughly 10 percent above spot might collect a premium of around 2 to 4 percent of the position value. That is income earned for the month, not a guaranteed or annualised return, and it is only repeatable if you sell a new call each period.
The main risk is opportunity cost: if the asset rallies sharply above your strike, your gains are capped at the strike while a simple holder captures the full move. The premium you collected partly offsets this, but in a strong bull run a covered call underperforms holding the asset outright. There is also full downside exposure on the underlying asset itself; the premium cushions a decline but does not protect against a large drop. A covered call does not lose more than holding the asset alone would.
Yes, but only because you still own the underlying asset. If BTC falls, your spot position loses value and the premium only partly offsets the loss. The covered call itself never adds risk beyond holding the asset; in every scenario the covered call position is worth more than holding the asset alone by exactly the premium collected. The loss comes from the asset, not from the call you sold.
A covered call is selling a call against an asset you already own to earn income and cap upside. A cash secured put is selling a put while holding enough cash or stablecoin to buy the asset if it falls to the strike, earning income while waiting to enter a position. Covered calls suit holders who want yield on existing exposure; cash secured puts suit buyers who want to get paid while waiting for a lower entry price. The two are mirror images on opposite sides of a holding.
Rolling means buying back your existing call and selling a new one, usually at a later expiry or higher strike. Traders typically roll when the asset is approaching the strike and they want to avoid assignment while keeping the position, or when the call has lost most of its value before expiry and they want to collect a fresh premium. Rolling up and out (higher strike, later date) lets you keep the asset and continue earning income, though it may require a small net debit.
Yes. Paradex is accessible globally including from India through a self-custodial wallet connection, giving traders a direct route to sell BTC covered calls without going through a centralised platform. The protocol offers low, transparent fees for retail accounts and a unified margin account that holds spot, perpetuals, and options together on Paradex Chain (StarkNet L2). The same experience applies for traders in Singapore, the UK, Brazil, and other global markets.
A covered call is a neutral to mildly bullish strategy. It performs best when the underlying asset stays flat or rises modestly toward but not far beyond the strike, letting you keep both the asset and the full premium. It underperforms a simple holding in a strong rally because upside is capped, and it offers only limited cushion in a sharp decline. It expresses the view that the asset will not move dramatically higher before expiry.
Ready to earn yield on the BTC you already hold? Open the Paradex options chain, switch to calls, choose a strike above the current price that you would be happy to sell at, and collect the premium. Low fees, self-custody, and institutional liquidity from the team behind Paradigm.
