Bitcoin has no native yield, so every way to earn yield on bitcoin is a second market layered on top: someone borrows your coins, someone pays for upside you sell, or a protocol routes your BTC into a strategy that does one of those things. The common paths are lending, BTCfi collateral strategies, and covered calls — each pays you for a different risk.
Three paths, three risks
| Path | What you are paid for | Core risk |
|---|---|---|
| Lending | Letting someone else use your BTC | The borrower or the platform fails to repay; forced selling in sharp falls |
| BTCfi strategies | Using BTC, usually as a wrapped token, in onchain finance | The wrapper's issuer, software faults, and the strategy itself |
| Covered calls | Selling upside above a strike | Capped upside; full downside still yours |
None of these is truly passive. Each path requires monitoring, and each can lose more than a period’s yield in a bad week.
Lending
You deposit BTC (or a wrapped form) into a lending market and earn a variable rate that rises and falls with demand to borrow. Income continues as long as borrowers pay and the market functions.
Fits if you want to keep full upside on BTC and accept credit and protocol risk for a variable rate.
Trade-off: rates fall when demand drops, and in a crisis many people withdraw at once. The yield does not hedge a BTC drawdown — you still hold the price risk of the coins you lent.
BTCfi
BTCfi is the umbrella term for bitcoin used in onchain finance: wrapped bitcoin (a token that stands in for BTC on another chain) posted as collateral, vaults that run a strategy for you, and other programs marketed as BTC yield. The label is broad; the risk is specific to each protocol.
Before depositing, verify:
- How your BTC gets there, and who holds the real bitcoin behind a wrapped token.
- What the strategy actually does with the collateral.
- Where yield comes from (borrower fees, trading profits, token incentives).
- What happens if the wrapper or the strategy fails.
High advertised rates often include reward tokens, which are not the same as income in BTC. Separate those when you compare.
Covered calls on BTC
You hold BTC, sell a call at a strike above the current price, collect premium, and accept that you may sell (or settle) at the strike if exercised. Premium is income for selling upside — not for eliminating downside.
A plain example
BTC trades at $100,000. You hold 0.5 BTC and sell a one-month call struck at $110,000.
- Collateral: 0.5 BTC reserved against the call you sold.
- Premium: say 0.014 BTC, about $1,400 (illustrative: close to what a one-month call 10% above the current price is worth with implied volatility in the mid-50s, where the Volmex bitcoin index stood on 6 October 2026; real premium comes from a book, vault, or RFQ).
- If BTC stays below $110,000: call expires; you keep 0.5 BTC + premium.
- If BTC is above $110,000 and exercised: you deliver or settle at the strike; further upside is gone.
Onchain, the same trade runs through order books, vaults, AMMs, or RFQ. Onchain covered calls covers the mechanics, and Crypto covered calls covers strike and expiry selection.
For a sense of what the trade pays and costs, Grayscale Research estimated in July 2026 that a bitcoin covered call could yield about 22% annualized if bitcoin moved sideways, assuming a $65,000 market price and 40% implied volatility. In the same example the position broke even near $58,500 and stopped beating plain bitcoin above roughly $72,500.
Covered call ETFs vs writing yourself
Packaged products run the covered-call strategy for you. Examples are bitcoin covered-call ETFs such as the Roundhill Bitcoin Covered Call Strategy ETF (YBTC), one of the funds in U.S. News's covered-call ETF roundup, and exchange products such as Binance's BTC Yield, which CoinDesk reported runs a systematic covered-call strategy with no guaranteed return. You get simplicity and a listed share; you give up strike selection, custody of the BTC, and typically a fee drag on the strategy. Whether that is worth it depends on whether you want the packaging or the control. The decision frame is the same as dual investment vs writing yourself — packaging vs terms.
How to choose
| Goal | Lean toward |
|---|---|
| Keep full BTC upside, accept credit risk | Lending |
| Use BTC inside DeFi strategies | BTCfi — with protocol-by-protocol diligence |
| Willing to sell upside above a strike for premium now | Covered calls |
| A ready-made covered-call product | Covered-call ETF or an exchange yield product |
If your real intent is “get paid while I wait to buy more BTC lower,” that is a cash-secured put, not a covered call — different collateral (stablecoins), same family of trades.
Covered calls on Overcast
On Overcast you request quotes to write covered calls on BTC: trading desks compete on premium, you collect it up front, settlement is onchain. The same flow covers ETH, SOL and tokenized stocks. The terms are explicit, and it is not a savings rate. How Overcast works.
FAQ
Lending, covered calls, or BTCfi — how to choose?
There isn’t one winner. Lending keeps upside and adds credit risk; covered calls pay you to sell upside; BTCfi depends entirely on the protocol. Match the path to the risk you accept, then compare after-fee premium or rate for the same horizon.
Is any of this “passive” income?
Every BTC yield path transfers risk in exchange for income. Name the risk first, then compare the rate or premium for that path.
What does BTCfi mean here?
Onchain finance that uses bitcoin, usually as a wrapped token, for lending, strategies or providing liquidity. Where the yield comes from and what can go wrong differ by protocol; check both before depositing.
Can covered calls protect me if BTC crashes?
No. Premium cushions part of a decline; it does not hedge it. A covered call still loses when the price falls.
