Perpetual Futures vs. Options: Which Is Right for You?
Perpetual futures vs. options for crypto — linear vs. non-linear P&L, the Greeks, funding vs. premiums, expiry risk, liquidity, and when to use each.
Both perpetual futures (“perps”) and options allow traders to speculate on the future price of cryptocurrencies and other assets without buying the underlying asset outright.
The pair are often used to amplify returns or hedge a trader’s existing positions.
But while similarities exist, the pair also have stark differences which may impact their best use, depending on one’s trading goals.
Below we’ll provide a comparison of the two trading types and explore when it may make the most sense to trade with one versus the other.
Perpetual Futures vs. Options at a Glance
Although both are derivative contracts, they work differently.
Perpetual Futures
A perpetual futures contract is a derivative that allows traders to speculate on an underlying asset without owning it. Unlike traditional futures contracts, perpetual futures contracts do not expire, therefore allowing traders to keep a position open indefinitely so long as margin requirements are met.
For example, instead of purchasing Bitcoin outright, a trader deposits collateral (margin) to open a leveraged long or short position. As the market moves, profits and losses are reflected in the position’s value.
To keep the perpetual futures prices in line with the underlying spot market, exchanges use a funding rate. On a set schedule, traders on one side of the market pay traders on the other side, depending on whether the perpetual contract is trading above or below the spot market.
Options
An option is a contract that gives the trader the right, but not the obligation, to buy or sell an asset at a predetermined price, known as the strike price, on a specified expiration date.
There are two primary option types:
- Call options give traders the right to buy an asset.
- Put options give traders the right to sell an asset.
Options differ from perps in that they require traders to pay an upfront premium to the option writer, or the seller of the options contract. This premium acts as the trader’s maximum possible loss when trading with options.
While on the surface the details may seem simple, options pricing is significantly more complicated than perpetual futures, as multiple variables can influence an option’s value at any given time.
Differences Between Perps and Options
One of the biggest differences between perpetual futures and options is how profits and losses are calculated.
Perps are said to have linear profit and loss, rising or falling in line with the price of the underlying asset.
On the other hand, options have non-linear profit and loss, meaning the valuation of an options contract will not merely track the asset’s price, but instead depend upon other variables like time decay or volatility.
Perpetual Futures: Linear P&L Example
With perps, a trader’s return is directly tied to the market’s price movement.
A worked example:
Imagine Bitcoin is trading at $100,000 and a trader deposits $1,000 as collateral and opens a 10x long perps position, creating a notional position value of $10,000.
If Bitcoin rises 5%, the position will gain approximately 50% (5% gain times 10x leverage) relative to the trader’s collateral, providing profits of around $500 in the scenario.
In the case that Bitcoin falls 5%, the trader’s position loses approximately 50% as well, leaving them with losses around $500.
Note: Funding payments and fees will affect the final calculation and are not accounted for in the following example.
Options: Non-Linear P&L Example
An option’s value depends on much more than the underlying asset’s price and instead relies upon multiple variables like, how far the option is in-the-money, how volatile the market is, and how much time is left until contract expiry.
Therefore, if a trader pays a high premium or there is significant time decay, the value of the options contract may erode even if the price moves in the right direction.
For example, imagine Bitcoin is trading at $100,000 and a trader buys a call option with the following:
- Strike price: $105,000
- Expiration: One month
- Premium paid: $1,000
In this example, the trader has paid a $1,000 upfront premium to the option seller to have the right to buy Bitcoin for $105,000 in one month.
If Bitcoin climbs from $100,000 to $104,000 in just a week after purchase, the option value may jump to $1,800 because there is still time for BTC to reach or exceed the strike price. If the trader sells their option at this point, they would net an $800 profit.
However, in a different scenario, Bitcoin may reach $104,000 within a few days of the contract’s expiry. Despite the same move, given that there are only a few days left to reach the strike price, the option could be valued below the $1,000 premium the trader paid, leading to a loss if the position is closed.
Because there are multiple variables at play, it’s possible for traders to correctly predict the direction of Bitcoin’s move and still lose money on an options trade.
Understanding the Greeks: Important Measures for Options Traders
For beginner options traders, understanding the “greeks” is where options may start to feel intimidating.
Largely named after letters in the Greek alphabet, the “greeks” in options trading are measurements that explain why an options price changes.
| Greek | What it Measures | Why it Matters |
|---|---|---|
| Delta | How much an option’s price changes when the underlying asset moves | Determines how sensitive your option is to price movement |
| Theta | Time decay | Every day closer to the contract expiry reduces an option’s value |
| Vega | An option’s sensitivity to market volatility | Options become more or less expensive as expected volatility changes |
| Gamma | How quickly delta changes | Shows how quickly an option will become more or less sensitive to price movements |
Find a more detailed breakdown of each below.
Delta
Delta measures how much an option’s premium is expected to change when the underlying asset’s price moves $1. It is measured on a scale of -1 to +1, where 0 means the premium will not really move even if the underlying asset’s price increases or decreases.
As an example, a Bitcoin call might have a delta of 0.5. In this example, as Bitcoin rises $1, the option’s value would theoretically increase by about $0.50.
As an option moves further into the money, its delta typically increases. This means that the option’s price begins to move more closely in line with the underlying asset.
Theta (Time Decay)
Every option has an expiration date. As that date approaches, the option gradually loses value, even if the price of the underlying asset doesn’t move at all.
That process is known as time decay.
Imagine a trader buying a one-month call option on Bitcoin because they expect it to rally.
If Bitcoin spends three weeks without much price movement, the option may have already lost a significant portion of its value simply because of the time that has elapsed.
This differs from perpetual futures. Because perps don’t expire, there’s no built in loss from time passage. Instead, a trader can keep the position open indefinitely so long as they have sufficient margin, ultimately benefitting when the price moves in line with their trade.
Vega
Vega measures how much the option premium will change when implied volatility increases or decreases by 1%, where implied volatility reflects how much the market expects prices to move.
Before big events, like FOMC meetings or protocol launches, implied volatility will likely rise because the market expects significant swings in price.
If vega is high, changes in volatility will result in bigger swings to the option’s price. When vega is low, the opposite is true, meaning that the option’s price is less impacted by implied volatility.
Gamma
Gamma is the measure of how quickly delta changes while the market moves.
In simple terms, gamma will tell a trader whether an option is becoming more or less sensitive to price movements.
High gamma values indicate that an option is likely to move more when the underlying asset moves.
Comparing Cost Structures: Funding Rates vs. Option Premiums
Another key difference between perps and options is how traders pay to open and maintain positions.
With options, the cost is paid upfront via a premium. With perpetual futures, collateral is required to open the position, but it is maintained via funding payments paid over time.
Options: Pay the Premium Upfront
When buying an option, the first cost is the premium.
If Bitcoin is trading at $100,000 and a trader purchases a one-month call option for $4,000, the $4,000 is paid immediately as a premium to the option writer or seller. In this example, it is also the maximum that the option buyer can lose.
If Bitcoin does not rise enough to make the option profitable prior to the contract expiration, it expires worthless and the premium is lost.
Perpetual Futures: Funding Instead of Premiums
While perpetual futures don’t require an upfront premium, opening a position requires a trader to post collateral (initial margin) to open a leveraged position.
Afterwards, to keep the contract open indefinitely, as there is no expiration date, traders exchange funding payments with traders on the other side of their long or short.
Unlike an options premium, funding can either reduce or improve overall returns depending on the market conditions.
Perpetual Futures vs. Options Comparison
| Feature | Perpetual Futures | Options (bought) |
|---|---|---|
| Upfront cost | None beyond required collateral | Premium paid in full upfront |
| Ongoing cost | Funding payments, typically every 8 hours | Theta (daily time decay) |
| Max loss | Collateral | Premium paid (capped) |
| Profit potential | Unlimited (leverage) | Unlimited (for calls) |
| Expiry | None | Fixed, option expires worthless if out of the money |
| Direction required? | Yes (long or short) | Not always (straddles profit from volatility) |
| Complexity | Low: leverage × price move | High: Greeks, strike selection, expiry |
| Crypto availability | Hundreds of markets | Mainly BTC and ETH |
| Liquidity | Very high (perps dominate crypto derivatives) | Reasonable for BTC/ETH, thin for altcoins |
Expiration Risk: A Big Difference in Perps and Options
Expiration risk is a key distinction between options and perpetual futures.
Consider an example where a trader purchases a Bitcoin call option with a $75,000 strike price and expiry in two weeks. If BTC does not reach $75,000 or beyond before the expiration, the option expires worthless even if the price rises above $75,000 in the week that follows.
Yet, a perps trader that maintains a position for the full three weeks will gain when BTC rises.
Being wrong on timing when trading perps will cost a trader funding rates and potentially some price fluctuation, but the position itself is not constrained by an expiration date.
A common mistake among new options traders stems from buying short-dated options in which they may be directionally right, but have the wrong timing.
While perps require a trader to ask a question about which direction the market is going, options asks them to determine whether it will move to a certain target before expiry.
Liquidity Comparison: Crypto Perps and Options
Perps have become the dominant form of crypto derivative trading with centralized and decentralized exchanges combining for more than $92 trillion in volume during 2025.
Those volumes consist of trading across hundreds of crypto assets, not just Bitcoin and Ethereum. For example, decentralized perps exchange Hyperliquid maintains millions in order book liquidity for many altcoins, allowing speculators to open positions across the crypto ecosystem.
Crypto options however currently maintain more concentrated asset liquidity. On Deribit, the leading crypto options exchange, traders may find sufficient liquidity for majors like Bitcoin, Ethereum, and Solana. However, many altcoin pairs are not available or thinly traded.
Furthermore, high implied volatility can make them expensive to trade.
When Options Might Be the Better Trading Tool
Though both trading tools may be available, there might be certain circumstances in which trading options instead of perps makes more sense.
For example, those who want more clearly defined risks may prefer to trade options, where the most they can lose is the premium.
Other times when options might be the better tool include:
- Event-driven trades: If a trader expects a major market move from an upcoming event or catalyst but they don’t know which direction, they may try an advanced options trade called a straddle. Using a straddle (a call and put with the same strike price) allows them to benefit on a major move in either direction.
- Selling premium for yield: Another advance strategy includes selling covered calls on spot positions to generate income. A trader can collect the premium as long as the asset stays below the strike price at expiry.
- Non-directional volatility plays: If a trader expects a strong volatility spike but doesn’t know which direction the market may move, enacting more advanced straddle or strangle trades allows them to profit from an increase in implied volatility.
When Perps Might Be the Better Trading Tool
On the other hand, trading perpetual futures may be better suited for those who are seeking simple directional bets.
For example, a trader who thinks Solana or another altcoin is going to go up can look to perps where ample trading options exist.
Other times when perps may be the better trading tool include:
- No time pressure: If a trader is confident in a trade and direction, but not sure the timing, perps allows them to hold as long as they wish so long as margin requirements are maintained.
- Shorting: Buying a put (the options equivalent of shorting) can be expensive during high-volatility periods. Shorts with perpetual futures are likely cheaper and simpler.
- Funding rate arbitrage: Traders using more advanced strategies can collect funding rates as yield, like going long spot and short perps if funding is positive.
Combined Approach: Perps and Options
Many experienced traders will make use of both perps and options as part of their active trading portfolio, using perps for active directional trades while leaning towards options for event-driven trades or hedging.
Imagine a trader with a core BTC spot position. They may use perps to tactically add or reduce their BTC exposure depending on intraday technical analysis. However, before a major FOMC meeting, they could hedge by purchasing a put, protecting their downside without closing their spot position.
Frequently Asked Questions
| Question | Answer |
|---|---|
| What is the difference between perps and options? | Perps have no expiry, while options maintain a set expiry date. Additionally, a perpetual futures value moves alongside the asset’s value. The value of an options contract is influenced by multiple variables, including time remaining and implied volatility. |
| Are perpetual futures better than options for speculation? | For simple directional trades, traders may prefer perps because they’re easier to understand. However, options also allow traders to speculate in the same manner. Use depends on a trader’s goals. |
| Do crypto options have time decay like stock options? | Yes, both crypto options and stock options measure and are influenced by theta, or time decay. |
| Can you lose more than your investment with crypto options? | If you’re buying options, your maximum loss is limited to the premium you paid. However, if you’re selling or writing uncovered options, traders could be liable for larger losses. |
| Why do most crypto traders use perpetual futures instead of options? | Crypto perps are often seen as simpler and are typically more liquid than crypto options. Plus, crypto perpetual futures contracts are generally available for a wider variety of crypto assets. |
Conclusion
Perpetual futures and options are both powerful trading instruments, but designed for different purposes.
For active crypto traders in particular, perpetual futures may be the more practical choice. They are simpler, highly liquid, and available across hundreds of crypto assets.
