Selling cash-secured puts on COIN
A crypto proxy with equity-market hours. IV in the 60s–90s is routine, the chain is liquid enough for spreads, and the overnight gap risk is real because the underlying asset trades while the options market is closed.
A cash-secured put is a limit order you get paid to place. Sell the Oct 30 $180 put on COIN and you collect $860 today for the obligation to buy 100 shares at $180. Set aside $18,000 to honour it and the premium is 4.8% over 33 days — 53% annualized.
The October 30, 2026expiry this analysis was built on has passed, so the contracts quoted below no longer trade. The structure and the strike-selection logic still hold; the prices do not. Open the builder for today’s strikes on the real chain.
The trade, priced from the chain

Every leg above is priced at the chain’s own quote — the identical number the builder will show you when you click through (last traded price), captured September 27, 2026 with a 15-minute delay. Only strikes whose print survives an implied-volatility check (within 20% of its own IV) and a no-arbitrage check across the ladder are priced here. Full methodology. Greeks, breakevens, max profit/loss and probability of profit are computed by OptionTracker’s engine at r = 4.2%. Educational analysis, not investment advice.
Yield on the capital this actually ties up
Annualized figures assume the same trade repeats every 33 days at the same premium. Nothing does. Use them to compare strikes and tickers, not to forecast a year.
How a cash-secured put works
Selling a put transfers the downside between $180 and zero to you, and you are paid $8.60 per share for taking it. "Cash-secured" simply means you hold the $18,000 required to buy the shares instead of leaning on margin. Same position, honest denominator.
At October 30, 2026: above $180 the put expires worthless and you keep $860 — that is the maximum this trade can make, $860. Below it you're assigned 100 shares at $180, with an effective cost basis of $171.4 once the credit is applied. That is 12.2% below where COIN trades today.
The engine puts the probability of keeping the full credit at 72% on COIN at $195.11 with 68% ATM implied vol on the Oct 30 expiry. High win rate, capped payoff, uncapped-to-zero loss — the risk profile of every short-premium trade. It is not free money; it is a rent cheque for underwriting someone else's insurance.
When it makes sense
- You genuinely want to own COIN at $180 — because roughly 72% of the time you won't get the shares, and the rest of the time you will, at the worst possible moment.
- IV is elevated relative to realized. At 68% ATM, COIN is the 2nd richest of the 20 underlyings on this site.
- It is the entry leg of the wheel: sell puts until assigned, then sell calls against the shares.
- The position survives the worst single session in this underlying's recent history at the size you are about to put on.
Where the risk actually is
Max loss is $17,140 — the strike, less the credit, times 100, if COIN goes to zero. That number is not theoretical on single names; it is simply unlikely. Size the position against that figure, not against the premium.
Assignment is not the loss — being assigned at $180 when COIN is at $144 is. If you are running the wheel, that is the moment the plan is tested: you own shares at a basis of $171.4 and the market disagrees.
Liquidity is a risk, not a convenience. The moment you most want out of a short-premium position is the moment the spread is widest, and the exit price you modelled at mid will not be available.
COIN specifics: ladder, surface, and the implied move
The premium is the highest per dollar of spot on this list and the honest reason is that the risk does not stop when the closing bell rings. Bitcoin trades all weekend; Coinbase options do not. A short strike that was two standard deviations away on Friday afternoon can be through the money before Monday's open with no opportunity to manage in between. Defined risk is not a preference here, it is the only responsible construction.
COIN's Oct 30 strikes are $2.5 apart near the money (1.28% of spot). That is a coarse ladder: one rung is a large fraction of the implied move, so precision on the short strike is an illusion. 8.2k contracts of open interest on Oct 30 is thin, and a structure that needs four separate fills will pay for it. 40 strikes on that expiry — 74% of the board — carry prints that agree with their own implied volatility and hold up across the ladder, and those are the strikes priced here. Workable around the money, genuinely thin in the wings. Price your condor width against the open interest, not the ladder.
Skew is inverted: the 25-delta CALL implies 12.7% more vol than the put. That is the market pricing upside risk above downside risk — a squeeze, a takeover rumour, or a crowded short. Selling calls into an inverted skew pays better than usual and is riskier than usual for exactly the same reason. The term structure is in contango: the back month implies 2.5% more vol than the front. Calm now, uncertainty later — which rewards selling the front month and makes the back month an expensive thing to own outright.
At 68% ATM implied vol, the Oct 30 options are pricing a one-standard-deviation move of $39.88 over 33 days — roughly −20.4% to +20.4%, or $155.23 to $234.99. A short-premium structure here is a bet that 20.4% over 33 days is more than COIN will actually use. That is the thesis, stated honestly.
The mistake this name punishes hardest: Weekend gap risk. Every other name on this list stops moving at the close on Friday; the asset behind this one does not.
Picking the strike on COIN
Put delta is the shorthand for assignment odds: a 0.30-delta put is roughly a 30% chance of being assigned at expiry. On COIN at $195.11, here is what the bands buy you:
| Band | What it means | When it fits |
|---|---|---|
| 0.10 – 0.16 Δ | Deep OTM, ~1 in 8 assignment | Pure premium harvesting. Small credits; one bad gap erases many wins.On COIN: the Oct 30 $167.5 put at $4.50, 30% annualized |
| 0.20 – 0.30 Δ | The thetagang standard | Best balance of credit, cushion and assignment odds for a wheel entry.On COIN: the Oct 30 $172.5 put at $6.07, 39% annualized |
| 0.40 – 0.50 Δ | Near the money | You want the shares. Largest credit, near coin-flip assignment.On COIN: the Oct 30 $190 put at $12.65, 74% annualized |
| ITM | You will almost certainly be assigned | A synthetic buy order with extra steps. Compare against just buying the stock. |
The live Oct 30 put chain below shows real deltas and mids from the capture, with each strike's credit expressed as a percentage of its strike — the cash you must set aside — and annualized on the same basis as the figures above. Compare the annualized column across strikes before you decide — the curve is rarely linear.
Across the nine rungs below, the premium runs 2.8× from the cheapest strike to the richest — that curve is the whole strike-selection decision, drawn. Open interest concentrates at $185 on this expiry, which is usually where the fills are cleanest.

Managing the position
- Roll down and out for a credit if the stock breaks your strike and you still want the exposure. Roll for a debit and you're just averaging into a losing thesis.
- Never close at $0.01 to "keep the streak". If the option is worth a penny, let it expire — that penny is a commission and a distorted P/L record. Track the close at $0.00, which is what actually happened.
- Decide the exit before the fill. A short-premium position with no stated profit target and no stated loss point is not a trade, it is a subscription to whatever the market decides.
- Roll for a credit or do not roll. A roll that costs money is a new trade financed by refusing to book a loss on the old one, and the accounting hides that from you.
Common mistakes
Selling puts on a stock you don't want
The premium looks the same on every ticker; the assignment doesn't. If you would not buy 100 shares of COIN at $180 with your own thesis, this is a naked short-vol bet, not an entry.
Selling through earnings without meaning to
A 33-day put on COIN may straddle bitcoin's tape. If the credit looks unusually rich, that is why — check the calendar before assuming you found an edge.
Trading the annualized number
Annualizing a 7-day credit assumes 52 identical weeks, none of which include the one that goes wrong. It is a comparison unit, not a return.
COIN cash-secured put FAQ
What is my cost basis if I get assigned?
$180 minus the $8.60 credit, so $171.4 per share — 12.2% below COIN's $195.11. Our wheel tracker carries that adjusted basis forward automatically through every subsequent call you write.
Is selling puts on COIN safer than buying the shares?
Slightly, and only below the strike. You give up all upside above $180 in exchange for 12.2% of downside cushion. Whether that trade is good depends entirely on whether 68% implied vol is expensive relative to what COIN actually does.
How much is COIN expected to move by Oct 30?
The Oct 30 options imply a one-standard-deviation move of $39.88 — about 20.4% of the COIN share price — over the 33 days to expiry. That is the market's estimate, not a forecast: roughly a third of the time the actual move is larger.
Is COIN option skew favouring puts or calls?
Calls. The 25-delta call implies 12.7% more volatility than the 25-delta put on the Oct 30 chain — an inverted skew, usually a sign of squeeze or event risk to the upside.
