What Are Options?

An options contract gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a specified price (called the strike price) on or before a certain date (called the expiration date). Unlike futures contracts, where both parties are obligated to fulfill the contract, options provide flexibility. The buyer can choose to exercise the option only if it is profitable to do so. If the option is not profitable, the buyer can simply let it expire, losing only the premium paid to purchase the option.

In the crypto world, options trading has grown significantly with platforms like Deribit leading the market. Bitcoin and Ethereum options are now actively traded, with daily volumes reaching hundreds of millions of dollars. Options provide crypto traders with powerful tools for speculation, hedging, and generating income from their existing positions.

The premium is the price you pay to purchase an options contract. This premium is determined by several factors including the distance between the current price and the strike price (intrinsic value), the time remaining until expiration (time value), the volatility of the underlying asset, and prevailing interest rates. Understanding these factors is essential for evaluating whether an options contract is fairly priced.

Call vs Put Options

There are two fundamental types of options: call options and put options. A call option gives the holder the right to buy the underlying asset at the strike price. Call options increase in value when the underlying asset's price rises. Traders buy call options when they expect the price to increase and want to profit from that movement without directly owning the asset.

A put option gives the holder the right to sell the underlying asset at the strike price. Put options increase in value when the underlying asset's price falls. Traders buy put options when they expect the price to decrease. Puts are also commonly used for hedging purposes, allowing investors to protect the value of their holdings against downside risk.

The buyer of an option is called the holder, while the seller of an option is called the writer. The writer collects the premium but takes on the obligation to fulfill the contract if the holder chooses to exercise it. This asymmetry between the rights of the holder and the obligations of the writer is fundamental to understanding options pricing and risk management.

Strike Price, Expiration, and Premium

The strike price is the price at which the option holder can buy (for calls) or sell (for puts) the underlying asset. The strike price is fixed at the time the option contract is created and does not change. Options with strike prices close to the current market price are called at-the-money options and typically have the highest liquidity.

The expiration date is the last date on which the option can be exercised. After expiration, the option becomes worthless. Options can have various expiration timeframes, from weekly options that expire in just a few days to LEAPS (Long-term Equity Anticipation Securities) that can last for two years or more. In crypto, most options have shorter expirations, typically ranging from one day to three months.

The premium is influenced by several components. Intrinsic value is the difference between the current price and the strike price, if that difference is favorable. Time value represents the remaining time value of the option, with more time typically meaning higher premiums. Implied volatility reflects the market's expectation of future price movements, with higher volatility leading to higher premiums across all strike prices.

Basic Options Strategies

Buying Calls: This is the most straightforward options strategy. You purchase a call option when you believe the underlying cryptocurrency will increase in price. Your maximum loss is limited to the premium paid, while your potential profit is theoretically unlimited as the price can rise indefinitely. For example, if you buy a BTC call option with a strike price of $70,000 for a premium of $2,000, and BTC rises to $80,000 at expiration, your profit would be $8,000 minus the $2,000 premium, giving you a net profit of $6,000.

Buying Puts: This strategy is used when you expect the price to decrease. You purchase a put option, giving you the right to sell at the strike price. Your maximum loss is limited to the premium paid, while your profit increases as the price falls. Buying puts is also an excellent hedging strategy for protecting existing long positions in your portfolio.

Covered Calls: This is an income-generating strategy where you own the underlying cryptocurrency and sell call options against your holdings. You collect the premium, which provides some income and downside protection. However, your upside is capped at the strike price. If the price rises above the strike price, your cryptocurrency will be called away at the strike price. This strategy works best in sideways or slightly bullish markets where you do not expect significant price appreciation.

Deribit: The Main Crypto Options Exchange

Deribit is the dominant exchange for crypto options trading, commanding over 80% of the market for Bitcoin and Ethereum options. Based in Panama, Deribit offers both European-style options (which can only be exercised at expiration) and various contract sizes to accommodate both retail and institutional traders. The platform provides advanced options analytics, including the ability to view the options chain, implied volatility surfaces, and Greeks (delta, gamma, theta, vega) for all available contracts.

For traders looking to get started with crypto options, Deribit offers a user-friendly interface and comprehensive educational resources. The exchange also offers a demo trading environment where you can practice options strategies without risking real capital. While other exchanges like OKX, Bybit, and Binance have also begun offering crypto options, Deribit remains the most liquid and feature-rich platform for serious options traders.

How Options Can Hedge Your Crypto Portfolio

Options are powerful hedging tools that allow crypto investors to protect their portfolios against downside risk while maintaining upside potential. The most common hedging strategy is buying protective puts. If you hold a large amount of Bitcoin and are concerned about a potential price decline, you can purchase put options that increase in value as Bitcoin's price falls. This effectively creates an insurance policy for your portfolio.

For example, if you hold 1 BTC worth $70,000, you could buy a put option with a strike price of $65,000 for a premium of $1,500. If Bitcoin drops to $55,000, your put option would be worth at least $10,000 (the difference between the $65,000 strike and the $55,000 market price), offsetting much of the loss on your spot holding. The cost of this protection is limited to the $1,500 premium paid, regardless of how far Bitcoin falls.
