Question 1

What is a poor man's covered call in crypto?

Accepted Answer

A poor man's covered call, or PMCC, is a diagonal spread that mimics a covered call for a fraction of the capital. Instead of buying the coin outright and selling a call against it, you buy a deep in-the-money, longer-dated call as your stand-in for the coin, then sell a near-dated out-of-the-money call against that long call to collect premium. The deep in-the-money long call has a high delta, so it moves almost one-for-one with the underlying like the coin would, but it costs a small fraction of the coin's price — often sixty to eighty percent less capital — because you are buying exposure, not the asset. The short call you sell is your income leg: it decays quickly, and if the coin stays below its strike you keep the whole premium and sell another one, exactly as you would rolling covered calls on spot. The appeal is capital efficiency and defined risk. Your worst case is the net you paid for the spread, not the full value of a coin that could fall a long way, and you free up the rest of your capital for other trades. The trade-offs are that your long call has an expiry and pays no coin yield, and a hard crash still hurts you — just less, in dollar terms, than holding the coin. It is a leveraged, capital-light way to run the covered-call income game on an asset you are bullish-to-neutral on.

Question 2

How much capital does a PMCC save versus buying the coin?

Accepted Answer

That is the whole point of the structure, and the saving is usually large. Buying one coin ties up its full price; the PMCC ties up only the net debit — the cost of the deep in-the-money long call minus the premium you collect on the short call. Because a deep in-the-money call is mostly intrinsic value plus a slice of time value, it can cost a quarter to a half of the coin's price, and the short-call premium shaves that down further, so the position often uses sixty to eighty percent less capital than owning the coin outright for a very similar delta of exposure. This calculator shows the exact figure: the net debit, the coin price it replaces, and the capital efficiency as a percentage. Freeing that capital is the benefit — you get covered-call-style income on a small footprint and can deploy the rest elsewhere — but it is also the risk, because a smaller outlay controlling the same exposure is leverage, and leverage cuts both ways. The dollar loss in a crash is smaller than holding the coin, yet as a percentage of the capital you put up it can be total: if the coin falls far enough, the long call can expire worthless and you lose the entire debit. Capital efficiency is a feature to use deliberately, not a free lunch.

Question 3

Where does the diagonal make its maximum profit?

Accepted Answer

Maximum profit on a PMCC comes when the underlying finishes right around the short call's strike at the short expiry. There the short call you sold expires just worthless or at-the-money, so you keep its full premium, while your long call — now deep in the money and still holding weeks or months of life — is worth the most it can be relative to what you paid. Push price higher than the short strike and the short call goes in the money against you, capping your gains: above the strike the extra rise in your long call is handed straight to the option you sold, exactly like a normal covered call caps out when the coin is called away. The subtlety a diagonal adds over a same-month covered call is that your long call keeps time value beyond the short expiry, so the true max profit is a little higher than the simple strike-minus-strike-minus-debit shortcut most guides quote. This calculator prices the long leg with Black-Scholes at the short expiry, so it shows both the modelled max profit including that leftover time value and the more conservative intrinsic figure, and it marks the short strike where the peak sits. The result is that a diagonal, well placed, can out-earn a plain covered call on the same capital while capping the same runaway upside.

Question 4

What are the risks of a diagonal spread?

Accepted Answer

The first risk is a deep, fast fall in the underlying. Your long call is leverage, so while the dollar loss is smaller than owning the coin, a big drop can take the long call's value down hard, and if price collapses far enough the call can expire worthless and you lose the entire net debit — a total loss of the capital you put up, even though the coin itself did not go to zero. The second is capped upside: if the coin rips far above your short strike, you are called away in effect, and every gain beyond the strike goes to the option you sold, so you miss the tail of a big rally in exchange for the premium you collected. The third is time and volatility on the long leg. Unlike a coin you can hold forever, your long call has an expiry and decays as it approaches it, fastest in the final stretch, and a drop in implied volatility lowers its value even if price is flat — so a PMCC held too long or opened when volatility is expensive can bleed value on the long side. Finally, there is roll risk: the strategy assumes you keep selling short calls at good premiums, and in a low-volatility or falling market those premiums may not be enough to matter. The strategy suits a bullish-to-neutral view on a coin, run with strikes and expiries you have modelled, not a set-and-forget position. This calculator prices the downside break-even and the capped max profit so both edges are visible before you open it.
