In the dynamic world of cryptocurrency trading, perpetual contracts have become a popular instrument. Among them, the coin-margined perpetual contract, often called a reverse contract, is a key product. Unlike USDT-margined contracts that use the stablecoin USDT as collateral, coin-margined contracts require the traded cryptocurrency itself—like BTC or ETH—to serve as margin. This fundamental difference shapes their unique characteristics and use cases.
For a coin-margined contract, you must hold the specific cryptocurrency to trade in its market. For instance, to trade a BTCUSD coin-margined contract, you need to deposit BTC as your margin. Essentially, you use a cryptocurrency to trade that same cryptocurrency, and your profits are also earned in that digital asset.
Both USDT-margined and coin-margined perpetual contracts operate without an expiry date, enabling 24/7 trading. They utilize a funding fee mechanism to tether the contract price to the spot market index. Traders can open long (buy) or short (sell) positions to speculate on price movements and capture gains from market fluctuations.
How Funding Rates Work
A critical component of perpetual contracts is the funding fee, which is not a charge by the platform but a transfer between long and short traders. This mechanism ensures the contract price stays aligned with the spot index price. The funding rate’s direction determines who pays and who receives.
When the contract price exceeds the spot price (positive funding rate), long positions pay funding fees to short positions. This incentivizes longs to close, pushing the price down. Conversely, when the contract price is below the spot price (negative funding rate), shorts pay longs, encouraging shorts to exit and driving the price up. This periodic exchange, typically every eight hours, helps maintain price convergence. Fees are only exchanged if you hold a position at the funding timestamp.
To protect traders during extreme volatility, exchanges employ safeguards like insurance funds and automatic deleveraging to mitigate losses from liquidations.
Trading with Coin-Margined Contracts
Coin-margined contracts support various markets, including BTC, ETH, and other major cryptocurrencies, with leverage options up to 100x. To start, select your desired market and leverage level, then deposit the corresponding cryptocurrency as margin. This allows you to enter positions and manage risk accordingly.

Who Should Use Coin-Margined Contracts?
For beginners holding primarily stablecoins like USDT, USDT-margined contracts are often more suitable. They simplify trading by using a stable asset for margin, making profit and loss calculations straightforward.
However, if you already hold cryptocurrencies like BTC or ETH and have some trading experience, coin-margined contracts can be advantageous. In a bullish market, profits earned in the native coin can amplify gains as the asset’s value rises. But be cautious: losses are also magnified if the market moves against you. Always assess your risk tolerance and market knowledge before trading.
Frequently Asked Questions
What is the main difference between coin-margined and USDT-margined contracts?
Coin-margined contracts use the base cryptocurrency (e.g., BTC) as collateral, while USDT-margined contracts use the USDT stablecoin. This affects margin requirements, profit calculation, and risk exposure.
How often are funding fees exchanged in perpetual contracts?
Funding fees are typically exchanged every eight hours. Only traders holding positions at these intervals participate in the payments.
Can I use leverage with coin-margined contracts?
Yes, leverage is available, often up to 100x, but it increases both potential profits and risks. Use it cautiously and understand the mechanics of margin calls.
What happens if my position is liquidated?
Exchanges may use insurance funds or automatic deleveraging to cover losses. However, you could still lose your initial margin if the market moves drastically against your position.
Is trading coin-margined contracts suitable for beginners?
It is riskier and more complex due to volatility in the margin asset. Beginners should start with USDT-margined contracts or practice with small positions to gain experience.
How do I choose the right contract type for my strategy?
Consider your portfolio composition, risk appetite, and market outlook. If you hold crypto assets and are bullish, coin-margined might fit. For stability and simplicity, USDT-margined could be better.
Remember, trading perpetual contracts involves significant risk. Educate yourself thoroughly and avoid following trends without understanding the market dynamics.
