Perpetual contracts are among the most popular derivatives trading instruments on Gate. With no expiration date, users can hold positions indefinitely. According to official Gate data, perpetual contracts account for the vast majority of the platform’s total contract trading volume, thanks to their ease of use and high leverage.
01 Quick Overview of Core Differences
Gate’s contract trading revolves around two main margin models: USDT-margined (USDT-M) perpetual contracts and coin-margined (BTC-M) perpetual contracts. The fundamental difference lies in the asset used for margin and settlement.
Before choosing, users should clarify which asset they want as the basis for trading and as the vehicle for final profits.
To make this clearer, the table below summarizes the key differences between the two contract types:
| Feature | USDT-Margined Perpetual Contract (USDT-M) | Coin-Margined Perpetual Contract (BTC-M) |
|---|---|---|
| Margin Asset | USDT | BTC |
| Quotation & PnL Settlement Currency | USDT (pegged directly to USD) | Quoted in USD, but PnL settled in BTC |
| Contract Value Calculation | Each contract represents a fixed amount of the underlying coin (e.g., 0.0001 BTC) | Each contract has a fixed value of 1 USD |
| Best For | Users who prefer fiat valuation, trade multiple coins, or focus on short-term trading | Long-term BTC holders, miners hedging, or those bullish on BTC’s value appreciation |
For example, when the BTC price is 50,000 USDT, if you go long with 10x leverage and BTC rises by 5%, your profit on a USDT-margined contract is 2,500 USDT. On a coin-margined contract, your profit is a greater amount of BTC.
02 USDT-Margined Contracts: The Stable and Intuitive Fiat Choice
USDT-margined contracts use USDT, which is pegged 1:1 to the US dollar, as both the margin and settlement unit. For most users—especially those coming from traditional financial markets—this is the most straightforward option.
The biggest advantage is simplicity in calculation. Whether it’s position value, margin requirements, or final PnL, everything is denominated in USDT. You can easily interpret a 500 USDT profit as roughly $500, greatly simplifying asset management and return calculations.
Another key feature is operational flexibility. By holding just USDT, you can trade contracts for BTC, ETH, ORDI, and hundreds of other cryptocurrencies on Gate. There’s no need to frequently swap between BTC, ETH, and other coins, saving both time and conversion fees.
For instance, if a trader is bullish on both ETH and SOL in the short term, they can use USDT from their account as margin to open USDT-margined positions in both assets simultaneously. The trading process is clear and straightforward.
03 Coin-Margined Contracts: Amplifying Bitcoin’s Value for True Believers
Coin-margined contracts, where BTC is used for both margin and PnL settlement, represent another classic model. These are especially suitable for those who are long-term bullish on Bitcoin and aim to grow their BTC holdings.
In a bull market, this contract type offers a dual appreciation effect. Suppose you use 1 BTC as margin to open a position and your trade is successful. Not only do you earn profits denominated in BTC (increasing your BTC balance), but the USD value of your margin and profits also rises as BTC’s price increases.
This makes coin-margined contracts a natural tool for miners and hedgers. Miners who continuously generate BTC can use a portion as margin to open hedging contracts, locking in future returns or protecting against downside risk—all without converting BTC to stablecoins.
However, keep in mind that since PnL is settled in BTC, sharp BTC price fluctuations can make your profits and losses in USDT terms feel more complex.
04 Scenario-Based Choices and Trading Guide
When choosing between the two contract types, your decision should be based on your trading objectives and position preferences.
If you’re a multi-asset short-term trader or want clear, USD-denominated PnL, USDT-margined contracts are your best bet. Their unified approach allows for greater flexibility in capital allocation and lets you seize opportunities across different coins.
If you’re a long-term Bitcoin believer or already hold significant BTC and want to hedge or grow your position without selling your BTC, coin-margined contracts are a better fit. They keep your assets fully within the Bitcoin ecosystem.
Once you’ve chosen your contract type, trading on Gate follows these clear steps:
- Funding and Transfer: Depending on your chosen contract type, make sure your contract account holds enough USDT or BTC as margin. Funds can be transferred from your spot account.
- Set Key Parameters:
- Margin Mode: Choose between "Isolated" and "Cross." In Isolated mode, each position’s margin is independent, isolating risk. In Cross mode, your entire account balance is shared as margin, offering greater resilience to volatility but with potential for cascading risk.
- Leverage: Some contracts on Gate support up to 125x leverage. Remember, leverage is a double-edged sword—it amplifies both gains and losses proportionally.
- Place an Order to Open a Position: Select your order type (limit, market, or conditional), enter price and quantity, and click "Buy/Long" or "Sell/Short" to execute.
- Risk Management: After opening a position, always monitor the "liquidation price." Use tools like "Take Profit/Stop Loss" or "Trailing Stop" to manage risk and lock in profits in advance.
05 Advanced Strategies and Risk Awareness
Once you master the basics, advanced strategies can further enhance your trading. For example, you can employ funding rate arbitrage.
When the funding rate for a perpetual contract is positive, longs pay shorts a fee. By "shorting the contract + holding an equivalent spot position," you can create a market-neutral strategy to earn funding rate income. This approach can provide relatively stable cash flow, even in volatile markets.
Regardless of your strategy, always respect the high risks of contract trading. High leverage means even minor adverse price moves can lead to significant losses. Be sure to understand the "forced liquidation" mechanism: if your margin balance falls below the maintenance margin level, your position will be automatically liquidated by the system.
Never risk more than you can afford to lose, and make full use of demo trading to practice.
Looking Ahead
A trader pauses on Gate’s BTC/USDT perpetual contract trading interface, where both USDT-margined and coin-margined options appear on the screen. With both USDT and BTC in his account, he ultimately chooses a coin-margined contract, opening a position with 0.1 BTC. He knows this is more than just a settlement choice—it’s a strong vote of confidence in the future of this decentralized asset over the next decade.
