Crypto Options Basics: Buyer Premiums, Seller Margin, and Liquidation
Summary
The document introduces crypto options as contracts that give the holder the right, but not the obligation, to buy or sell at a specified price before expiry. It explains that buyers pay a premium upfront, which caps their loss, and uses a Bitcoin call example to illustrate how a favorable price move can make an option valuable while an out-of-the-money option may expire worthless. It also notes that options can be used for hedging, speculation, or structured exposure across market conditions.
The main risk distinction is between buyers and sellers. Sellers receive the premium but must post margin because losses may exceed that amount; the exchange may liquidate a seller’s position if the maintenance margin ratio reaches its stated threshold. The document advises monitoring margin, setting alerts, understanding expiry, and sizing positions carefully. It is a basic overview tied to one platform’s rules and does not explain option valuation, strategy construction, or how margin and execution behave under all market conditions.
Key ideas
- An option buyer pays a premium for the right, but not the obligation, to trade at a specified price before expiry.
- The buyer’s loss is limited to the premium, while an option seller may lose more than the premium received.
- Option sellers must maintain collateral and may be liquidated if their maintenance margin ratio reaches the stated threshold.
- Expiry and time decay affect an option’s value and should match the trader’s intended horizon.
- The overview gives basic mechanics but does not cover valuation methods or detailed strategy design.
