Most crypto holders manage risk in only two ways: they sell, or they hope. Options offer a third route. With a put option you can set a floor under a position you want to keep, and with a collar you can do it for little or no upfront cost. Thanks to self-custodial options venues, these tools are no longer reserved for professional desks. This guide walks through how protective puts and collars work, what they really cost, and where people commonly go wrong.

Options in one paragraph

A put gives its buyer the right, but not the obligation, to sell an asset at a fixed price (the strike) until a set date (the expiry). A call gives the right to buy at the strike. The buyer pays a premium upfront; the seller collects it and takes on the obligation. The key property for risk management is that a bought option has a defined maximum loss: the premium. That is what makes puts behave like insurance rather than like a leveraged bet.

The protective put: insurance with a deductible

Suppose you hold 10 ETH and want to keep them through a risky quarter. You buy 10 put options with a strike about 10% below the current price, expiring in three months. If ETH falls 40%, the puts gain value and offset most of the loss below the strike. If ETH rises, the puts expire worthless and you keep all of the upside, minus the premium you paid.

Think of the parts like an insurance policy:

• The strike is your deductible. The gap between today’s price and the strike is the loss you still absorb yourself. A strike closer to the current price protects more, but costs more.
• The premium is your insurance payment. It is lost if nothing bad happens, just like a home insurance premium.
• The expiry is the length of the policy. Longer protection costs more in total, though usually less per day.

The collar: trading upside for cheaper protection

Premiums on crypto puts can be expensive, especially when markets are nervous. A collar reduces that cost by pairing the put with a call you sell. Using the same 10 ETH example, you might buy puts 10% below the current price and sell calls 15–20% above it. The premium you collect from the calls pays for some or all of the puts.

The result is a position with a floor and a ceiling. Below the put strike you are protected; above the call strike your gains stop, because you are obliged to deliver your ETH at the call strike. Between the two strikes your position behaves normally. Derive, an onchain options exchange, describes the collar as particularly practical for large holders precisely because it can bring the net cost of hedging close to zero (Derive).

A collar is a good fit when you mainly care about surviving a crash and would be content selling at the upper strike. It is a poor fit if you hold because you expect a huge rally, because that is exactly the scenario the collar gives away.

What drives the price of protection

The single biggest factor in what a put costs is implied volatility, the market’s expectation of future price swings. When fear is high, puts get expensive, often sharply. That leads to the most important practical rule of hedging: buy protection while markets are calm, not after a crash has already started. Waiting for “more certainty” usually means paying more for the same cover.

The other drivers are time and distance. Every day a bought option loses a little value through time decay (theta), and puts far below the current price are cheap because the market considers a fall that deep unlikely. Cheap, far out-of-the-money puts can still make sense as disaster insurance, but they will not help in an ordinary 20% correction.

Onchain or centralized?

For years the crypto options market was dominated by Deribit, which Coinbase acquired in a deal that closed in August 2025 (The Block). Centralized venues still tend to offer the deepest liquidity. Onchain venues such as Derive let you keep collateral in smart contracts you control, use portfolio margin across multiple legs, and in some cases post BTC or ETH directly as collateral instead of converting to stablecoins.

Neither choice removes risk; it changes its shape. On a centralized exchange you take counterparty and custody risk. Onchain you take smart contract, oracle and liquidity risk. A hedge is only as good as your ability to exercise or close it when you need it, so check the depth of the order book at your chosen strike and expiry before you rely on it.

Common mistakes when hedging with options

1. Hedging the wrong size. Protecting 100% of a position is expensive. Many holders hedge a portion, for example half, and accept some exposure on the rest.
2. Mismatched expiry. If the risk you worry about is six months away, a two-week put will expire before it matters.
3. Forgetting the obligation on a sold call. In a collar, the short call is a real commitment. If the price rockets, you must deliver or buy the call back at a loss.
4. Treating protection as a one-off. Hedges expire. A risk plan needs a rule for rolling them, or a conscious decision to let them lapse.
5. Ignoring liquidity. Wide bid-ask spreads on thin strikes can quietly cost more than the premium itself.

Democratising risk management

Options used to feel like an institutional tool wrapped in jargon. In practice, a protective put is simply insurance with a deductible, and a collar is insurance you pay for by agreeing to a selling price in advance. Understanding those two structures gives any long-term holder more choices than “sell everything” or “do nothing” the next time the market turns rough.
