Protective Put
A protective put is a hedge: you keep holding an asset and buy a put option on it, which gives you the right to sell at a set price. If the price falls below that level, the put's gains offset your losses, at the cost of the premium you paid.
How a protective put works
A put option gives its buyer the right to sell an asset at a fixed price, the strike price, at or before expiry. If you already own the asset, buying a put on it works like insurance. Below the strike, every further drop in your holdings is matched by a gain in the put. Above the strike, the put simply expires and you keep the upside, minus what you paid.
The price of that insurance is the option premium. You choose the trade-off yourself: a strike close to the current price protects more but costs more, a strike far below costs less but leaves a bigger gap before protection starts. Longer expiries cost more in total, though often less per month.
A worked example
Say you hold 1 BTC at 60,000 and buy a three-month put with a strike of 54,000 for a premium of 2,000. If bitcoin falls to 40,000 at expiry, your coin has lost 20,000, but the put pays 14,000 (54,000 minus 40,000). Your total loss is 6,000 plus the 2,000 premium, so 8,000. That is the most you can lose in this setup, whether the price ends at 50,000 or at 30,000.
If bitcoin instead rises to 70,000, the put expires worthless. You gained 10,000 on the coin and spent 2,000 on the put, so you are up 8,000 rather than 10,000.
Protective put vs. stop-loss
A stop-loss order is free to place but turns into a market sale when triggered. In a sudden crash it can fill far below its level, and once sold you miss any rebound. A put cannot be gapped through: its payout is fixed by the strike, and you keep the coins. The difference is that the put costs money up front, every time.
Weak spots and how people lose money
Repeated hedging adds up. Paying 2,000 every quarter is 8,000 a year, and in calm or rising markets that cost is simply lost. Puts are most expensive right after crashes, when implied volatility is high, which is exactly when many people decide they want protection.
The protection ends at expiry, so a crash one day later is not covered. Mismatches also hurt: a put on bitcoin does not fully protect a portfolio of smaller coins, and a contract size that differs from your holdings leaves part uncovered.

Frequently asked questions
What is the maximum loss with a protective put?
Roughly the gap between your purchase price and the strike, plus the premium paid. In the example, buying at 60,000 with a 54,000 put costing 2,000 limits the loss to 8,000 until expiry.
Is a protective put the same as a married put?
Mostly yes. A married put usually means buying the asset and the put at the same time, while a protective put can be added to an asset you already hold.
Can I sell the put before it expires?
Yes. If the price has fallen, the put has gained value and can be sold to lock in that gain instead of waiting for expiry.
