Cryptocurrency Put Options: Payoffs, Breakeven, and Risk
Summary
This lesson explains cryptocurrency put options, including contract terms, expiry settlement, buyer and seller payoffs, and breakeven calculation. A put gives its buyer the right to sell at the strike. Using a Bitcoin example, the text shows that an out-of-the-money put expires worthless, while an in-the-money put pays the strike-to-settlement difference, converted into BTC on the described venue. It derives a breakeven price from the strike and premium and illustrates the calculation with example contracts.
The lesson compares buying puts with short futures. A long put limits the buyer’s loss to the premium and avoids liquidation from a temporary price spike, but the premium pushes breakeven below the strike and the option expires if the anticipated move is too slow. Put sellers collect at most the premium but face potentially large losses if Bitcoin falls, particularly when exposure is measured in BTC. The examples reflect a particular contract and settlement convention; they are educational illustrations, not a complete treatment of option valuation or all exchange rules.
Key ideas
- A put gives its buyer the right to sell the underlying asset at the strike on expiry.
- The buyer’s payoff depends on the settlement price relative to the strike and the premium paid.
- For the settlement convention shown, breakeven is below the strike and depends on the premium.
- Buying a put limits loss to the premium but adds time decay and timing risk.
- Selling a put earns at most the premium while exposing the seller to substantial downside losses.
