COIN strangle: the breakevens nobody quotes

Both legs are pure extrinsic value, so the strangle is a leveraged bet that COIN travels further than 73% implied vol says it will over 27 days. Between the strikes at expiry, both expire worthless and you lose the entire $812.

The payoff is a valley: flat max loss between $130 and $172.5, then linear gains once past the breakevens at $121.88 and $180.62. Max profit is unlimited.

Compared with the straddle at the same expiry, you pay less and need more. That is not a free improvement — it is a different bet, with a lower probability of profit (32% here) and a bigger multiple when it works.

Gamma is lower than a straddle's while the stock sits between the strikes, so the position responds sluggishly to the first part of a move and then accelerates. Traders consistently underestimate that lag.

Max loss $812 is the base case, not the tail. The stock finishing anywhere between $130 and $172.5 — the range it spends most of its life in — wipes out the position.

Double theta with no offset: two long options bleeding simultaneously. Over 27 days that decay is the single largest determinant of the outcome if the move is late.

Pinning is not exotic. The most likely single close for a quiet underlying is near the strike you bought, and that is where a long-vol structure loses the most.

One of the few names where a long straddle can be justified on level rather than timing: realized vol has repeatedly exceeded implied over multi-week windows when crypto trends. The cost is that theta on a 70-vol ATM straddle is punishing, so the position needs the move within weeks, not months.

COIN's Aug 28 strikes are $2.5 apart near the money (1.71% of spot). On a ladder that wide, "pick the 0.30 delta strike" resolves to whichever rung happens to be closest — sometimes not close at all. 5.5k contracts of open interest on Aug 28 is thin, and a structure that needs four separate fills will pay for it. 27 strikes on that expiry — 33% 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 1.7% more vol than the put. That is the market pricing upside risk above downside risk — a squeeze, a takeover rumour, or a crowded short. Owning upside on an inverted skew means paying the expensive side of the surface, which is worth knowing before you buy the call. The term structure is flat inside 1.5% between the two captured expiries, so there is no calendar edge to harvest and no event visibly priced into one month over the other.

At 73% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $28.93 over 27 days — roughly −19.8% to +19.8%, or $117.33 to $175.19. Owning vol here means believing COIN covers more than 19.8% in 27 days, and covering it in time.

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.
