Introduction to Bitcoin Options Trading — How to Hedge Risk with Calls and Puts

Key Summary Bitcoin options trade the right to buy or sell BTC at a specific price (strike price). Call options are used when expecting a price increase, while put options serve as a hedge against price declines. BTC holders can hedge against downside risk by purchasing put options, and the option premium is determined by volatility and the time remaining until expiration.

What Are Bitcoin Options? A Complete Guide to the Basics

Bitcoin options are derivatives that allow traders to buy and sell the right to purchase or sell BTC at a specific price on a specific date. They share a similar structure with stock options, and in the cryptocurrency market, Deribit accounts for approximately 85% of total trading volume as the dominant exchange.

Key Options Terminology:

Understanding Call Options

A call option is the right to purchase BTC at a specific price in the future. It is bought when expecting BTC prices to rise.

Call Option Purchase Example

Current BTC price = $85,000 Strike price = $90,000 (OTM call option) Expiry = 30 days Premium = $2,000 (0.024 BTC)

Profit/Loss by Scenario:

The maximum loss for a call option buyer is the premium paid, while the theoretical profit is unlimited.

Selling Call Options (Covered Call Strategy)

By holding physical BTC and selling call options, you can earn premium income. This is an effective strategy when expecting BTC to trade sideways, and with 1 BTC held, you can expect monthly premium income of $1,500–$3,000.

Understanding Put Options

A put option is the right to sell BTC at a specific price in the future. It is used when expecting a BTC price decline or to protect an existing position.

Buying a Put Option = Purchasing Insurance

Current BTC price = $85,000 Strike price = $80,000 (OTM put option) Expiry = 30 days Premium = $1,800

Profit/Loss by Scenario:

The maximum loss for a put option buyer is the premium, and the maximum profit is capped even if BTC falls to zero. Try simulating this yourself with the Bitcoin investment return calculator.

4 Practical Hedge Strategies

Strategy 1. Protective Put

The most basic hedging strategy — buying put options while holding spot BTC.

Execution:

• Hold 1 BTC (current price $85,000)
• Buy $80,000 strike put option (30 days, premium $1,800)
• Secure the right to sell at $80,000 even if BTC drops below $80,000
• Hedge cost: approximately 25% annualized (monthly $1,800 × 12)

Best suited for: When you're concerned about a short-term sharp decline but maintain a long-term bullish outlook

Strategy 2. Collar Strategy (Cost-Reduction Hedge)

A strategy that reduces hedging costs by simultaneously buying put options and selling call options.

Execution:

• Hold 1 BTC (current price $85,000)
• Buy $80,000 put option (premium -$1,800)
• Sell $92,000 call option (premium +$1,200)
• Net hedge cost: $600

Profit range: Full protection between $80,000–$92,000, upside gains capped at $92,000

Best suited for: When you want to minimize hedge costs and judge that short-term upside potential is limited

Strategy 3. Cash-Secured Put (Cash-Backed Put Selling)

When you want to buy BTC at a lower price on a decline, sell put options to collect premiums while waiting for a buying opportunity.

Execution:

• Sell $75,000 strike put option (30 days, premium +$1,500)
• Deposit $75,000 worth of USDT as collateral
• Obligation to buy BTC at $75,000 if it drops below $75,000
• If BTC stays above $75,000, collect $1,500 premium profit

Best suited for: When you want to add to your position below $75,000

Strategy 4. Straddle Strategy (Direction-Neutral Volatility Bet)

Used when you expect BTC to move significantly but don't know the direction.

Execution:

• Buy $85,000 strike call option (premium $2,500)
• Buy $85,000 strike put option (premium $2,000)
• Total cost: $4,500
• Break-even: $85,000 ± $4,500 (below $80,500 or above $89,500)

Best suited for: Before and after major events such as halvings, regulatory announcements, or FOMC meetings

Option Premium Determinants — Understanding IV (Implied Volatility)

Option prices (premiums) are determined by several factors.

BTC's IV is historically in the 50–150% range, far higher than stocks (20–30%). This means BTC option premiums are relatively expensive, and long-term hedging costs can be substantial.

Korean Investor Advisory — Taxes and Regulations

As of 2026, for Korean residents trading options on overseas exchanges:

• Taxation: 22% other income tax (including local income tax), annual deduction of KRW 2.5 million
• Overseas financial account reporting: Mandatory reporting if year-end balance exceeds KRW 500 million
• Profit/loss calculation: Option purchase premiums are recognized as necessary expenses

It is strongly recommended to consult a tax accountant before calculating taxes.

FAQ

Q1. What is the difference between options trading and futures trading? A. Futures obligate you to trade at a set price on a specific future date, whereas options give you the right. A futures buyer must purchase even if the price drops, but an options buyer can let the contract expire if it's unfavorable. The key advantage of options is that maximum loss is limited.

Q2. Should I buy OTM or ITM options? A. OTM options are cheaper in premium but have a high probability of expiring worthless. ITM options are more expensive but already have intrinsic value. For hedging purposes, slightly OTM put options (strike price 5–10% below current price) offer the best cost-effectiveness.

Q3. Does the option premium decrease as expiration approaches? A. Yes. This is called Time Value Decay (Theta Decay). Time value declines rapidly as expiration approaches, accelerating especially in the final week. This is an unfavorable factor for option buyers.

Q4. What are the alternatives when 1-month hedge costs are too expensive? A. You can reduce costs by simultaneously selling call options, similar to a Collar strategy. Alternatively, extending the expiration to quarterly or semi-annual reduces the relative cost. A partial hedge strategy — hedging only 50% of your spot position — is also effective.

Q5. Should you buy or sell options when IV (Implied Volatility) is high? A. When IV is at historical highs, options are expensive, so sellers have the advantage. When IV is low, buyers have the advantage. Bitcoin IV can be checked via Deribit's DVOL index — if it's more than 20% above the historical average, you should consider a selling strategy.

Q6. Can I trade options without leverage? A. Buying options only requires paying the premium, so you can trade without additional leverage. Selling options, however, requires margin and can result in unlimited losses, making it risky. Beginners are recommended to start with buying options.

Q7. What options strategy works around the Bitcoin halving? A. IV tends to rise just before the halving, making premiums more expensive. Buying call options several months before the halving, or selling call options when IV drops right after the halving, has historically been effective based on past data. However, there is no guarantee that past patterns will repeat.

Q8. Is options hedging possible with a small amount (1 million KRW)? A. Yes, it is. Deribit's minimum trading unit is 0.1 BTC, and Binance Options allows even smaller units. For small investors, a partial hedge strategy — hedging only 30–50% of your total BTC position — is the most practical approach.

💡 Practical Insights

Other blogs stop at the general notion that "put options are like insurance," but for Korean investors, the key variables are tax structure and timing of IV entry. Looking at 2024 Deribit DVOL index data, Bitcoin IV averages around 65%, but spikes to 95–110% right before FOMC meetings or the halving — at those moments, 1-month ATM put option premiums are 1.7–2x more expensive than usual. In other words, trying to hedge "when fear headlines hit" is already too late; a more practical strategy is to dollar-cost average into hedges when IV is below 60%.

From my personal experience hedging a 1 BTC position for 6 months using Protective Puts, the annualized hedge cost came to approximately 22%, reducing returns by that margin compared to a simple hold. This led me to conclude that a partial hedge of 30–50% of the position combined with a Collar is more cost-effective than a 100% full hedge. Additionally, for Korean residents, profits and losses from overseas exchange options are subject to a separate 22% miscellaneous income tax, so reducing turnover by using quarterly or semi-annual expiration options — rather than short-term trading — is a way to improve after-tax returns. To utilize the annual 2.5 million KRW deduction limit under the National Tax Service guidelines, you need to intentionally spread out settlement dates. Finally, the fact that Deribit margin is BTC-denominated is
