Are you curious about how traders can hold leveraged positions on Bitcoin and other assets without an expiration date? This article explains the mechanics of crypto perpetual contracts, the risks involved, and how you can approach them responsibly.
The plain explanation
A perpetual contract is a type of derivative that lets you speculate on the price movement of a cryptocurrency without actually owning the underlying asset. Unlike traditional futures, perpetual contracts have no set expiry date, so you can keep the position open indefinitely, provided you meet the margin requirements.
To open a perpetual contract, you deposit margin—a fraction of the total contract value—into a trading platform. This margin acts as collateral that protects the platform against losses if the market moves against you. The amount of leverage you can use (often 2x to 100x) determines how large a position you can control relative to your margin.
Because there is no expiry, the contract price needs to stay close to the spot price of the cryptocurrency. This is achieved through a funding mechanism: at regular intervals (usually every eight hours), long and short positions exchange a small payment called the funding rate. If the contract trades above the spot price, longs pay shorts; if it trades below, shorts pay longs. The funding rate aligns the contract price with the underlying market.
When you close a position, any profit or loss is settled in the quote currency (often US dollars or a stablecoin). If the market moves sharply against you and your margin falls below a maintenance threshold, the platform may automatically liquidate your position to protect the system. This liquidation can happen quickly and may result in a loss greater than your initial margin.
A real example
In March 2026, the cryptocurrency exchange BitMEX announced that it would shut down after 11 years of operating. BitMEX was one of the earliest platforms to offer perpetual contracts on Bitcoin and other assets. Its closure highlighted how dependent perpetual trading is on the health and policies of the exchange hosting the contracts. Users were forced to close or transfer their positions, underscoring the importance of platform risk in perpetual trading.
What it means for you
If you are looking to earn passive income or generate short‑term gains, perpetual contracts can provide high leverage and the ability to profit from both rising and falling markets. However, the same leverage that amplifies gains also magnifies losses. You must be prepared for rapid margin calls and possible liquidation.
Because funding rates can be positive or negative, they can either add to your profit or become an ongoing cost. Monitoring the funding schedule is essential, especially for positions you plan to hold for several days.
Finally, the platform you choose matters. An exchange’s liquidity, security measures, and governance policies directly affect the safety of your funds and the reliability of contract pricing.
What to check / how to judge
- Liquidity and volume: Higher trading volume reduces slippage and ensures you can enter and exit positions at expected prices.
- Funding rate history: Review past funding rates to gauge typical costs or earnings for long or short positions.
- Margin requirements: Understand the initial and maintenance margin percentages; lower margins increase liquidation risk.
- Platform security: Look for audits, insurance funds, and a transparent governance structure.
- Liquidation mechanisms: Know how quickly the platform can liquidate positions and whether there is a safeguard fund to cover shortfalls.
FAQ
Do I need to own the underlying cryptocurrency to trade a perpetual contract?
No. Perpetual contracts are settled in the quote currency, so you can trade them without holding the actual crypto.
How often is the funding rate paid?
Most platforms calculate and exchange the funding rate every eight hours, but the exact schedule can vary.
Can I lose more than my initial margin?
On most reputable exchanges, losses are limited to the margin you posted because positions are liquidated before the loss exceeds that amount. However, extreme market moves can sometimes result in a small deficit.
Is perpetual trading suitable for long‑term investors?
Perpetual contracts are primarily designed for short‑term speculation. Long‑term investors typically benefit more from holding the actual cryptocurrency or using staking and other passive‑income strategies.
