A protective put is the simplest, most reliable form of crypto portfolio insurance. You buy a put option that gives you the right to sell at a fixed price, no matter how far the market falls. For Indian crypto holders on CoinSwitch Pro, protective puts turn an open-ended downside risk into a defined, manageable cost.
This guide explains how protective puts work, how they beat stop-loss orders, how to choose strikes and expiries that fit your budget, and how to manage continuous protection over time.
What Is a Protective Put? (Insurance Analogy)
The clearest mental model is home insurance.
You own a house. You pay an annual premium to an insurance company. If the house burns down, the insurance pays out. If nothing happens, you have paid the premium without claiming.
A protective put works the same way. You own BTC. You pay a premium to the options market. If BTC crashes, the put pays out. If BTC stays steady or rallies, the put expires worthless and you have paid the premium without claiming.
You Own BTC, You Buy the Right to Sell It at ₹X
If BTC is at ₹65,00,000 and you buy a ₹62,00,000 put, you have the right to sell your BTC at ₹62,00,000 anytime before expiry.
If BTC crashes to ₹50,00,000, you exercise the put and sell at ₹62,00,000. You have lost ₹3,00,000 per BTC from the spot peak (the difference between ₹65,00,000 and ₹62,00,000) instead of ₹15,00,000.
Maximum Loss = Premium Paid, Downside Fully Protected Below Strike
The premium is your maximum out-of-pocket cost on the hedge. Below the strike, your downside is fully neutralised by the put’s gain.
This is the most powerful feature of options as insurance: defined maximum cost.
Protective Put vs Stop-Loss Order: Why Options Win
Many traders default to stop-loss orders. Options usually offer better protection in crypto.
Stop-Loss Gets Triggered on Flash Crashes and Recovers, You’re Out
A stop-loss is a market order triggered at a specific price. In a flash crash, your stop can execute at far below the trigger price (slippage). If BTC recovers within minutes, your stop has already sold and you missed the rebound.
Crypto flash crashes happen frequently. A stop-loss at ₹62,00,000 might execute at ₹58,00,000 in a panic, even if BTC closes the day at ₹64,00,000.
The Put Option Protects You Without Closing Your Spot Position
A protective put keeps your spot intact. The put’s gain offsets the spot’s loss. If BTC recovers, your put can also rally back in value (or expire worthless if BTC ends above the strike), but you still own your BTC.
For volatile, manipulable, flash-crash-prone markets like crypto, options are structurally superior to stop-losses.
How to Choose Your Strike Price
Strike selection trades cost against coverage.
ATM Put (Expensive, Full Protection) vs OTM Put (Cheaper, Partial)
An ATM put has a strike at the current price. Maximum protection. Maximum cost.
An OTM put has a strike below the current price. You absorb some downside before protection kicks in. Lower cost.
For a one-month BTC put on a ₹65,00,000 spot, an ATM put might cost ₹1,80,000. A 10% OTM put (strike at ₹58,50,000) might cost ₹40,000 to ₹60,000.
The 10% OTM Rule: Affordable Protection for Most Indian Holders
10% OTM is a commonly used balance. You absorb a 10% pullback before protection activates, but you cap the worst case beyond that.
The annualised cost is typically 4% to 8% of spot value, depending on IV. This is comparable to the cost of equity downside protection in volatile markets.
For more conservative protection, use 5% OTM strikes. For ultra-budget protection, use 15% to 20% OTM strikes that only kick in during real crashes.
How to Choose Your Expiry
Expiry selection affects cost and management overhead.
Monthly vs Quarterly: Cost vs Convenience Comparison
Monthly puts: lower premium per contract, more rolling activity required, finer cost calibration.
Quarterly puts: higher premium per contract (but lower per-month), less rolling, longer commitment.
For most retail Indian crypto holders, monthly puts are the standard. They provide continuous protection with manageable overhead.
Rolling the Put: Maintaining Continuous Protection
A put expires. To maintain protection, you must roll into the next contract.
Roll mechanic: a few days before expiry, sell the current put (if any value remains) and buy the next month’s put at a similar strike. The cost of the new put is a fresh premium expense.
Calendar discipline matters. Set reminders to avoid unhedged gaps.
Real INR Example: Protecting a ₹10L ETH Portfolio
ETH at ₹3,50,000. You hold 2.86 ETH (₹10,00,000 worth).
Buy a one-month 10% OTM put: strike ₹3,15,000. Premium per ETH: roughly ₹15,000 (illustrative, depends on IV).
Total premium: 2.86 × ₹15,000 = ₹42,900 for one month.
Annualised cost: roughly 5% per year (12 × ₹42,900 = ₹5,15,000 on a ₹10,00,000 portfolio).
This protection caps your maximum monthly loss at roughly 10% (the OTM buffer) plus the small premium cost. In exchange, you give up 5% per year in expected return.
For a holder who values capital preservation, this trade-off is often worth it. For an aggressive HODLer, the cost may feel too high.
Setting Up the Protective Put on CoinSwitch Pro
The execution flow.
Confirm your spot holdings in the portfolio view.
Open the BTC or ETH options chain. Select the target expiry (monthly is standard). Find the strike at 8% to 12% OTM (Delta roughly -0.20 to -0.30).
Tap BUY on the put side. Enter quantity matching your spot exposure. Confirm the premium debit. Submit.
The put appears in your positions. Monitor it weekly. If BTC moves significantly, reassess strike appropriateness. If BTC crashes through your strike, you have realised the protection; consider closing the put for a gain or holding to expiry for full payout.
The Cost of Protection: Is It Worth It?
The right answer depends on your risk tolerance and time horizon.
Annualised Cost of Continuous Protective Put Coverage
Continuous 10% OTM monthly puts on BTC typically cost 4% to 8% of portfolio value per year. ETH protection costs slightly more due to higher IV.
This is real money. Over five years, you may spend 20% to 40% of your initial portfolio value on protection.
The math justifies it only if you would otherwise sell into crashes (and miss recoveries) or if you cannot afford a 50% drawdown emotionally.
When Protection Is Most Cost-Effective (High IV = Expensive, Wait)
Buy puts when IV is low (IV Percentile under 30). Premiums are cheap. Protection is unusually affordable.
Avoid buying puts at peak IV (IV Percentile above 80). You overpay for protection and the IV crush after a vol spike can erode the put’s value even if BTC has not moved.
This is “IV-aware hedging” applied to puts specifically.
Key Takeaways
A protective put is the cleanest way to insure a crypto portfolio against crashes. You keep your BTC or ETH. You pay a defined premium. Your maximum downside is capped at the put strike (plus the premium cost).
Choose strike based on budget and risk tolerance. 10% OTM is a balanced default. Monthly expiries are easiest to manage. Roll into the next contract a few days before expiry to maintain continuous protection.
Annualised costs of 4% to 8% are typical and meaningful. Decide whether the peace of mind and recovery participation justify the cost. For long-term holders unwilling to sell into crashes, protective puts almost always do justify the cost.
FAQs
Q: How expensive is a protective put really? For BTC at typical IV (80% annualised), a one-month 10% OTM put costs roughly 0.5% to 1% of spot value per month. Annualised, 5% to 10%.
Q: What strike should I choose for the best balance? 8% to 12% OTM is the most commonly used balance. Cheaper than ATM, more responsive than 20% OTM.
Q: How often should I renew my protective put? Monthly is standard. Roll a few days before expiry to maintain continuous protection.
Q: Does a protective put protect against IV crush? No. If IV falls sharply after you buy the put, the put loses value through Vega even if BTC has not moved. This is why buying puts at low IV is preferred.
Q: Can I close the put early if BTC rallies hard? Yes. If BTC rallies and the put becomes deep OTM, you can close it at its remaining value (small but non-zero) to free up capital, or simply let it expire worthless.
Q: How is protective put premium taxed in India? The premium paid is the cost basis. If the put expires worthless, the full premium is a realised loss. If exercised or sold for a gain, the difference is the realised P&L. Under Section 115BBH (conservative interpretation), losses cannot offset spot gains.
Q: Can I use put spreads instead of single long puts? Yes. A bear put spread (long higher strike put, short lower strike put) is cheaper but caps the protection at a level. Useful for moderate-crash protection on a budget.
