What Is a Covered Call?

A covered call is selling a call option against BTC you already own — earn premium upfront, agree to sell BTC at the strike price if exercised. "Covered" means your short call is backed by actual BTC spot holdings (not a naked short call). It's the most beginner-friendly options income strategy.
I use covered calls on my BTC position when I want to earn yield on holdings I plan to keep long-term. The mechanics are simple: I deposit BTC on Deribit, sell an OTM call at a strike above current price, collect the premium in cash, and wait. If BTC stays below the strike at expiry, I keep the full premium and run the trade again. If BTC rallies above the strike, my BTC gets sold at that price — I still keep the premium, but miss the gains above the strike.
The covered call does three things: it generates income (premium), it reduces your effective cost basis on BTC, and it caps your upside above the strike. Best deployed in sideways or slow-uptrend environments when you don't expect a violent BTC rally within the trade window.

P&L Formulas and BTC Example
Max profit = premium + (strike − cost basis). Breakeven = BTC purchase price − premium received. These two numbers lock in your entire risk/reward picture at entry. Run the math before every trade.

Key Numbers
Max Profit

Cost basis reduction: Selling the $95K call for $1,500 on a $88K BTC position effectively reduces my cost basis to $86,500. If BTC stays flat for 12 months and I do this monthly at ~$1,500/month, that's $18,000/year in premium income — over 20% annualized yield on my BTC position.
P&L Scenarios — Hold 1 BTC at $88K, Sell $95K Call, $1,500 Premium
| BTC at Expiry | Combined P&L | Notes |
|---|---|---|
| Below $86,500 | Loss | BTC at $80K: lose $8K on BTC spot, keep $1,500 premium → net loss $6,500 |
| $86,500 | Breakeven | Breakeven: $88,000 cost basis − $1,500 premium received |
| $88,000 | +$1,500 | BTC flat: keep BTC + full $1,500 premium = $89,500 effective value |
| $90,000 | +$3,500 | BTC up $2K: unrealized gain $2K + $1,500 premium = $3,500 total |
| $91,500 | +$1,500 (call) | BTC at $91,500: call goes ITM — P&L from spot rises but offset at $95K cap |
| $95,000 | +$8,500 | Max profit: BTC sold at $95K (+$7K gain) + $1,500 premium = $8,500 total |
| Above $95,000 | +$8,500 (capped) | Upside capped: BTC called away at $95K regardless of how high it goes |
Strike Selection
Sell calls at delta 0.20–0.30 OTM to balance premium income with the probability of keeping your BTC. The right delta depends on how attached you are to your BTC and your current IV environment.
Strike selection is the most important decision in a covered call. The further OTM you go (lower delta), the safer your BTC is — but the less premium you collect. The closer to the money (higher delta), the more premium — but greater risk of assignment. I sell at 0.20–0.25 delta for long-term BTC holders who want income without aggressively risking their stack.
Delta vs Strike Selection — BTC at $88,000 (28 DTE)
| Delta | Strike (~) | Premium (~) | Annualized | Assignment Risk |
|---|---|---|---|---|
| 0.10 delta | ~$102,000 | $600 | ~18% | Low |
| 0.20 delta | ~$97,000 | $1,100 | ~22% | Low-Medium |
| 0.25 delta ⭐ | ~$95,000 | $1,500 | ~25% | Medium |
| 0.30 delta | ~$93,000 | $2,000 | ~30% | Medium-High |
| 0.35 delta | ~$91,500 | $2,500 | ~35% | High |
⭐ = Ron's preferred delta range. Premiums are approximate; real quotes depend on live IV.
Golden Rule
Only sell a call at a strike you'd be comfortable selling your BTC at. If BTC reaches $95K and gets called away, are you okay with that outcome? If yes → sell the $95K call. If you don't want to sell BTC at any price → covered calls are not for you.
High IV Rule
When BTC IV is elevated (DVOL above 60%, IV Rank above 50), sell farther OTM for the same premium you'd collect at a closer strike in normal IV. High IV means the 0.20 delta call is further from current price — giving you more upside buffer for the same premium income.
Expiry Selection
28–45 DTE is the sweet spot for theta decay and manageable commitment. Weekly calls maximize annualized yield but require active management every 7 days. Monthly calls are easier to run for most BTC holders.
Weekly (7 DTE)
Max YieldSelling weekly 0.10 delta calls consistently on BTC can generate ~25%+ annualized yield from premium alone. The trade-off: you must manage expiry, select a new strike, and execute every single week. One missed week or a bad entry after a Friday pump kills the cycle. Best for active traders who check positions daily.
Monthly (28–45 DTE)
RecommendedMonthly expirations at 28–45 DTE give theta time to work without requiring weekly monitoring. Premium is lower per week than daily/weekly rolls, but the best risk-adjusted profile for most BTC holders. Enter once per month, set an alert at 50–75% profit capture, and let theta do the work. This is my default cadence.
Quarterly (60–90 DTE)
Lower YieldLonger expirations collect more absolute premium but lower annualized yield. Theta decay is slow in the early weeks of a 90-day option. Better for very passive holders who don't want to manage the position. Strike is much further OTM at 60–90 DTE for the same delta, giving even more upside buffer.
Roll early rule: Close the position when you've captured 50–75% of the original premium. Don't hold to expiry for the final 25–50%. Opening a new 28–45 DTE cycle early frees up capital and maximizes annualized theta collection. A $1,500 premium position captured at 75% ($1,125) in 15 days frees you to open a new 28-day cycle with another $1,500 — far better annualized than holding the remaining $375 for another 13 days.
Greeks
Positive theta, reduced net delta, short vega — time decay works in your favor every day BTC stays below the strike. The covered call's Greeks are fundamentally income-friendly.
Theta (Θ)
Positive — time decay adds to your P&L every day
Theta is your primary profit engine in a covered call. Every day BTC stays below the strike, the sold call loses a little value. At 28 DTE with a $95K call priced at $1,500, theta might be roughly +$50–$80/day — rising as expiry approaches. This is passive income from your BTC holding. The closer to expiry without BTC moving above the strike, the more of the premium you get to keep.
Net Delta (Δ)
Reduced from 1.0 to 0.75 — still long BTC, less exposed
Holding 1 BTC = delta 1.0. Selling a 0.25 delta call → net delta = 1.0 − 0.25 = 0.75. You're still long BTC but with 25% less price exposure above the strike. A $1,000 BTC move up adds $750 to your portfolio P&L (not $1,000) because of the short call's negative delta contribution. This reduced delta is the mathematical expression of the upside cap.
Vega (V)
Short vega — enter when BTC IV is elevated for best premiums
Selling the call makes you short vega on that leg. If IV falls after entry, the call decreases in value faster than expected — you can buy it back cheaply and keep most of the premium early. Enter covered calls when BTC DVOL or IV Rank is elevated (above 50%) to maximize the premium you collect for a given strike. Low IV environments produce thin premiums and poor risk/reward for covered calls.
2026 Real-World Examples
In 2026, both GameStop and Goldman Sachs adopted covered call strategies on Bitcoin — signaling that covered calls on BTC are no longer a retail-only niche but a mainstream institutional yield strategy.
GameStop (March 2026)
Corporate TreasuryGameStop held 4,709 BTC on its corporate treasury and launched an OTC covered-call income strategy — selling calls against its BTC holdings to generate quarterly cash flow. Reported by CoinDesk in March 2026. This is the first major public company to formally deploy covered calls on a BTC treasury position rather than just holding spot.

Goldman Sachs (April 2026)
ETF FilingGoldman Sachs filed the Bitcoin Premium Income ETF — a fund that buys IBIT (BlackRock's Bitcoin ETF) and sells monthly OTM call options on the position. The fund is designed to deliver regular income distributions to investors from the call premiums, similar to equity covered call ETFs like JEPI. Reported by Fortune in April 2026.

Retail BTC Holders (Ongoing)
Retail StrategyIndividual BTC holders running weekly 0.10 delta covered calls on Deribit can generate approximately 25%+ annualized premium income on their holdings when IV is in the 50–70% range. If rolled consistently over 12 months at roughly $600–$1,000/week premium (on 1 BTC at $88K), the income compounds into significant cost basis reduction.
Based on Deribit live IV data, April 2026
Takeaway: When Goldman Sachs and GameStop are using covered calls on BTC, it's not a fringe retail strategy anymore. The mechanics are the same whether you're running it on $88K of BTC or $400M of IBIT. Sell the call, collect the premium, keep or deliver the BTC — that's the whole strategy.
How to Place a Covered Call on Deribit
On Deribit, deposit BTC as collateral, then sell an OTM BTC call. Below the strike at expiry: keep premium, BTC stays in your account. Above the strike: cash-settled in BTC — no physical delivery.
Deribit is my platform of choice for covered calls because BTC options are cash-settled — meaning if the call goes ITM and gets exercised, you receive or pay the difference in BTC, not physically deliver your BTC position. This matters for custody: your BTC stays on Deribit as margin during the trade, not sent anywhere.
Deposit BTC to Deribit as collateral
Transfer BTC to your Deribit account. This BTC serves as collateral for the short call. You don't need to deposit any USD. Deribit uses BTC (and sometimes USDC) as collateral for options positions.
Navigate to BTC Options → Select Expiry
Click BTC Options in the top menu. Choose your target expiry date (e.g., 28–45 days out). The options chain shows all strikes with live bid/ask prices and delta values per strike.
Find your target strike at 0.20–0.25 delta
In the options chain, look at the "Delta" column under Calls. Find the strike with delta closest to 0.20–0.25 (typically 8–10% above current BTC price at 28 DTE). This is your target call to sell.
Sell the call → confirm premium → submit
Click "Sell" on the target strike. A confirmation box shows: strike, expiry, premium you'll receive, margin required. Verify the premium matches your target. Submit. Premium is credited to your account immediately.

Rolling a Covered Call
Roll when the call goes deep ITM or with 7–10 DTE remaining. Rolling means buying back the current call and selling a new one at a higher strike or later expiry — ideally for a net credit.
Rolling is how covered call sellers stay in a BTC position when the price runs toward or above the strike. Instead of being called away, you roll the short call out in time or up in strike. The key rule I never break: only roll for net credit. If you have to pay a debit to roll, it means the premium you receive on the new position doesn't cover the cost of buying back the old one — that's a losing roll.
Roll Up and Out
Buy back the current $95K call. Sell a new call at $98K–$100K on a later expiry (e.g., roll from 28 DTE to 56 DTE). The higher strike gives BTC more room to run before assignment; the extra time generates enough new premium to cover the buyback cost and net you a credit. Best when BTC is approaching the strike and you want to stay in the position.
Roll Out in Time (Same Strike)
Keep the same $95K strike but sell a later expiry. Buy back 14 DTE $95K call, sell 42 DTE $95K call for a net credit. You gain 28 more days of theta at the same strike. This works when BTC hasn't reached the strike yet but you want to add more premium income and extend the income cycle at your current strike.
Never pay a debit to roll. If the roll costs you money (debit), you're locking in a guaranteed loss on the roll. In that case, either close the position and accept being called away at the strike, or wait for IV to decrease and the call to lose value before rolling. Paying debit rolls is one of the most common covered call mistakes.
Risks of Covered Calls
Covered calls cap your BTC upside above the strike. The biggest risk isn't assignment — it's missing a major BTC rally. If BTC goes from $88K to $150K and your call was at $95K, you capped yourself at $8,500 profit while BTC itself gained $62,000.
BTC surges above strike — upside capped, BTC sold (or cash-settled)
If BTC rips from $88K to $120K and you sold the $95K call, your max profit is $8,500 ($7K BTC gain + $1,500 premium). BTC without the covered call would be worth $32,000 more per coin. This is the primary cost of covered calls: you give up the tail upside in exchange for regular premium income. Avoid selling covered calls right before anticipated major breakouts.
BTC crashes — premium cushions but doesn't eliminate downside
If BTC falls from $88K to $60K, the $1,500 premium reduces your net loss to $26,500 (vs $28,000 without the call). The premium is a cushion — not a hedge. You still have full downside exposure to BTC price risk. Covered calls are not a bear market strategy. If you expect a major BTC drawdown, selling calls is not sufficient protection.
Avoid when expecting a strong BTC bull breakout
Don't sell covered calls heading into a major catalyst that could trigger a BTC breakout above your strike — ETF approvals, halving runs, major institutional announcements. If you suspect BTC could run 20%+ in the next 30 days, the premium you collect ($1,500) is not worth capping a $17,600 rally. Covered calls shine in flat to slow-moving markets, not before breakouts.
