Options trading has become a cornerstone of modern financial markets, offering traders powerful tools for speculation, hedging, and income generation. Whether you're new to derivatives or looking to deepen your understanding of crypto-based options, this guide breaks down everything you need to know—from core concepts like call and put options to advanced topics such as pricing models and settlement mechanics.
What Are Options?
An option is a type of derivative contract that gives the buyer the right—but not the obligation—to buy or sell an underlying asset at a predetermined price (known as the strike price) on or before a specific expiration date. This flexibility makes options a versatile instrument in both traditional and decentralized finance (DeFi) ecosystems.
Options are widely used across asset classes, including stocks, commodities, and increasingly, cryptocurrencies like Bitcoin ($BTC) and Ethereum ($ETH). Their growing popularity in DeFi platforms stems from their ability to manage risk and enhance yield strategies without requiring direct ownership of the underlying assets.

Types of Options
There are two primary types of options: call options and put options. Each serves a distinct purpose depending on market outlook and risk tolerance.
Call Options
A call option grants the holder the right to purchase the underlying asset at the strike price before or on the expiration date. Traders typically buy call options when they anticipate a rise in the asset’s price.
For example:
A trader purchases a Bitcoin call option with a strike price of $50,000, expiring in one month. If Bitcoin’s price rises above $50,000 during that period, the trader can exercise the option and buy BTC at the lower strike price, capturing the difference as profit.
This strategy allows investors to gain exposure to upward price movements with limited downside risk—limited to the premium paid for the option.
Put Options
A put option gives the holder the right to sell the underlying asset at the strike price before expiration. Put options are commonly used when traders expect a decline in asset value or want to hedge against potential losses.
For example:
An investor buys an Ethereum put option with a strike price of $3,000, expiring in two weeks. If ETH drops below $3,000, they can still sell it at $3,000 via the option, minimizing their loss.
Put options act as insurance for crypto holders, protecting portfolios during volatile downturns.
Option Positions: Buyer vs. Seller
Every options trade involves two counterparties: the buyer (long position) and the seller (short position).
Long Position (Option Holder/Buyer)
The buyer pays an upfront fee called the premium to acquire the option. If the market moves favorably and the option ends up in-the-money (ITM), the buyer receives a payout upon settlement.
- Advantage: Limited risk (only the premium paid)
- Goal: Profit from directional moves or hedge existing positions
Short Position (Option Writer/Seller)
The seller collects the premium from the buyer but assumes the obligation to fulfill the contract if the buyer exercises it. While this generates immediate income, it also exposes the seller to potentially unlimited risk—especially in volatile markets.
- Advantage: Earn consistent income from premiums
- Risk: Obligated to settle if the option becomes ITM
Understanding both sides of the trade is essential for building balanced strategies.
American vs. European Options
Options are categorized by when they can be exercised:
- American-style options: Can be exercised at any time before expiration. This added flexibility often makes them more expensive than European options.
- European-style options: Can only be exercised on the expiration date. Due to less flexibility, they tend to have lower premiums.
Most DeFi-based options follow European-style exercise rules for simplicity and predictability in automated systems.
Practical Use Cases of Options
Options aren’t just theoretical instruments—they serve real-world purposes in trading and investment strategies.
1. Speculation
Traders use options to bet on future price movements with leverage. For instance, buying a call option on Bitcoin allows participation in upside gains without purchasing BTC outright.
2. Hedging
Crypto holders can protect their portfolios using put options. A validator staking Ethereum might buy puts to limit losses if ETH’s price drops unexpectedly.
3. Income Generation
Investors holding large amounts of crypto can write (sell) call options against their holdings. They collect premiums while retaining ownership—benefiting from both income and potential appreciation, assuming the price stays below the strike.

How Are Options Priced?
Option pricing is complex and influenced by several key factors. The most widely used model is the Black-Scholes model, which estimates fair value based on:
- Underlying asset price: Current market price of the asset
- Strike price: Price at which the option can be exercised
- Volatility: Degree of price fluctuation (higher volatility = higher premium)
- Time to expiration: More time increases the chance of favorable movement
- Risk-free interest rate: Typically assumed near zero in DeFi contexts
In decentralized platforms like those using Constant Liquidity AMM (CLAMM) models, implied volatility (IV) is often derived from historical data:
- For $BTC and $ETH, IV may be sourced from Deribit, interpolated based on closest strike prices
- For assets like $ARB, beta-adjusted historical volatility relative to $ETH is used
Higher volatility leads to higher premiums because there's a greater probability of the option expiring ITM.
Option Settlement Process
Settlement occurs only if an option expires in-the-money (ITM). Out-of-the-money (OTM) or at-the-money (ATM) options expire worthless.
ITM Conditions
- Call Option: Spot price > Strike price
- Put Option: Spot price < Strike price
Settlement Calculation
- Call Option Payout: Number of options × (Spot price – Strike price)
- Put Option Payout: Number of options × (Strike price – Spot price)
The payout comes from the seller’s collateral pool. Note: The initial premium paid is not included in settlement but factored into overall profit/loss calculations.
Understanding Moneyness
"Moneyness" describes an option’s intrinsic value based on its current relationship between spot price and strike price.
1. Out-of-the-Money (OTM)
- No intrinsic value
- Call OTM: Spot price < Strike price
Example: $ETH call option with $2,000 strike when spot is $1,800 - Put OTM: Spot price > Strike price
2. At-the-Money (ATM)
- Spot price equals strike price
- No immediate value upon exercise
- Example: $ETH call/put with $1,800 strike when spot is $1,800
3. In-the-Money (ITM)
- Has intrinsic value
- Call ITM: Spot price > Strike price
Example: $ETH call with $1,600 strike when spot is $1,800 - Put ITM: Spot price < Strike price
Frequently Asked Questions (FAQs)
Q: Can I lose more than my initial investment when buying options?
A: No. As an option buyer, your maximum loss is limited to the premium paid.
Q: What happens if I sell an option that expires ITM?
A: You must fulfill the contract obligation using your collateral. Your loss equals the payout minus the premium received.
Q: Are crypto options settled in cash or physical delivery?
A: Most DeFi platforms use cash settlement in stablecoins or native tokens, rather than delivering the actual asset.
Q: How does volatility affect option prices?
A: Higher volatility increases uncertainty about future prices, leading to higher premiums due to increased ITM probability.
Q: Can I trade options on altcoins like ARB or SOL?
A: Yes. Many platforms support options on major altcoins using volatility proxies and beta adjustments relative to ETH or BTC.
Q: Is options trading suitable for beginners?
A: While complex, starting with simple strategies like buying calls or puts can help newcomers learn risk management and market dynamics.
