Introduction to Bitcoin Options Trading - How to Hedge Risk with Call/Put Options

Key Summary Bitcoin options trade the right to buy or sell BTC at a specific price (the strike price). Call options are used when you expect prices to rise, while put options are a way to prepare for a decline. Spot BTC holders can hedge downside price risk by buying put options, and option premiums are determined by volatility and the time remaining until expiration.

Key answer: Bitcoin options are a useful tool for hedging price volatility risk.

What Are Bitcoin Options? A Complete Guide to the Basics

Bitcoin Options are derivatives that let you buy and sell the right to buy or sell BTC at a specific price on a specific date. They have a structure similar to stock options, and in the cryptocurrency market, Deribit is the leading exchange, accounting for about 85% of total trading volume.

Key option terms:

Understanding Call Options Completely

A call option is the right to buy BTC at a specific price in the future. You buy it when you expect the BTC price to rise.

Example of Buying a Call Option

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

Profit by scenario:

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

Selling a Call Option (Covered Call Strategy)

If you sell call options while holding spot BTC, you can earn premium income. This is an effective strategy when you expect BTC to move sideways, and if you hold 1 BTC, you can expect monthly premium income of $1,500 to $3,000.

Understanding Put Options Completely

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

Buying a Put Option = Buying Insurance

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

Profit by scenario:

The maximum loss from buying a put option is the premium, and even if BTC goes to zero, the maximum profit is fixed. Try simulating it yourself with the Bitcoin investment return calculator.

4 Practical Hedging Strategies

Strategy 1. Protective Put

This is the most basic hedging strategy: you buy a put option while holding spot BTC.

How to execute:

• Hold 1 BTC (current price $85,000)
• Buy a put option with an $80,000 strike price (30 days, $1,800 premium)
• Secure the right to sell at $80,000 even if BTC falls below $80,000
• Hedging cost: about 25% annualized ($1,800 per month × 12)

Best suited for: Cases where you are concerned about a short-term sharp drop but maintain a long-term bullish outlook

Strategy 2. Collar Strategy (Cost-Reduction Hedge)

This strategy lowers hedging costs by buying a put option and selling a call option at the same time.

How to execute:

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

Profit range: Fully protected between $80,000 and $92,000, with upside capped at $92,000

Best suited for: When you want to minimize hedging costs or believe short-term upside is limited

Strategy 3. Cash-Secured Put

When you want to buy BTC at a lower price if it falls, this strategy lets you sell a put option, receive a premium, and wait for a buying opportunity.

How to execute:

• Sell a put option with a $75,000 strike price (30 days, premium +$1,500)
• Deposit $75,000 worth of USDT as collateral
• If BTC falls below $75,000, you are obligated to buy BTC at $75,000
• If BTC stays above $75,000, you earn the $1,500 premium

Best suited for: When you want to buy more BTC if it drops below $75,000

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

Use this when you expect BTC to move significantly but do not know the direction.

How to execute:

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

Best suited for: Around major events such as halvings, regulatory announcements, and FOMC meetings

What Determines Option Premiums - Understanding IV (Implied Volatility)

Option prices (premiums) are determined by several factors.

BTC's IV has historically been around 50-150%, far higher than stocks (20-30%). This means BTC option premiums are relatively expensive, and long-term hedging costs can be quite high.

Notes for Korean Investors - Taxes and Regulations

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

• Taxation: 22% miscellaneous income tax (including local income tax), with an annual deduction of KRW 2.5 million
• Overseas financial account reporting: Mandatory reporting if year-end balances are KRW 500 million or more
• Profit/loss calculation: Premiums paid when buying options are recognized as necessary expenses

It is advisable to consult a tax accountant before calculating taxes.

FAQ

Q1. What is the difference between options trading and futures trading? A. Futures create an obligation to trade at a set price on a specific future date, while options are rights. A futures buyer must buy even if the price falls, but an options buyer can walk away (let it expire) if it becomes unfavorable. The advantage of options is that maximum loss is limited.

Q2. Should I buy OTM options or ITM options? A. OTM options have cheaper premiums but are more likely to expire worthless. ITM options are expensive but already have intrinsic value. For hedging, slightly OTM put options (strike prices 5-10% below the current price) are cost-effective.

Q3. Does the premium fall as the option gets closer to expiry? A. Yes. This is called time value decay (Theta Decay). As expiry approaches, time value falls sharply, especially during the final week. This is an unfavorable factor for option buyers.

Q4. What are the alternatives when a one-month hedge is too expensive? A. You can lower the cost by selling call options alongside the hedge, as in a Collar strategy. Or you can extend the expiry to quarterly or semiannual options to reduce the relative cost. A partial hedge strategy that hedges only part of the spot position (50%) can also be effective.

Q5. When IV (implied volatility) is high, should I buy options or sell them? A. When IV is at a historical high, options are expensive, so sellers have the advantage. When IV is low, buyers have the advantage. Bitcoin IV can be checked through Deribit's DVOL index, and if it is more than 20% above the historical average, you should consider selling strategies.

Q6. Can I trade options without leverage? A. Buying options only requires paying the premium, so it can be done without separate leverage. Selling options, however, requires margin and can involve unlimited losses, making it risky. Beginners are advised to start with buying options.

Q7. What options strategy works around the Bitcoin halving? A. Right before the halving, IV rises and premiums become expensive. Historical data suggests that buying call options several months before the halving, or selling call options after the halving when IV falls, has been effective. However, there is no guarantee that past patterns will repeat.

Q8. Can I hedge options with a small amount (KRW 1 million)? A. Yes. Deribit's minimum trade size is 0.1 BTC, and Binance Options supports even smaller trade sizes. For small investors, a partial hedge strategy that hedges only 30-50% of the total BTC position is more realistic.

💡 Practical Insight

Other blogs stop at the general idea that "put options are insurance," but for Korean investors, the important variables are the tax structure and timing based on IV. Looking at 2024 Deribit DVOL index data, BTC IV averages around 65%, but it can surge to 95-110% right before events such as FOMC meetings and halvings. At those times, one-month ATM put option premiums are 1.7-2 times more expensive than usual. In other words, if you try to hedge after "fear-driven news" has already broken, you are already late. A more realistic strategy is to buy in portions when average IV is 60% or lower.

After personally hedging a 1 BTC position with Protective Puts for six months, I found that the annualized hedging cost was about 22%, reducing returns by that amount compared with simply holding. For that reason, I concluded that a partial hedge covering only 30-50% of the position combined with a Collar is more cost-effective than a 100% full hedge. In addition, for Korean residents, options gains and losses on overseas exchanges are separately taxed as miscellaneous income at 22%, so using quarterly or semiannual expiry options to reduce turnover is a way to improve after-tax returns compared with short-term trading. To use the annual KRW 2.5 million deduction under Statistics Korea and National Tax Service guidelines, it is necessary to intentionally spread out settlement timing. Finally, the fact that Deribit margin is BTC-based means
