What is the difference between USDT-margined and coin-margined contracts on KuCoin?

Understanding Margin Types in KuCoin Futures Trading

When engaging in futures trading on KuCoin, traders are presented with two primary margining systems: USDT-margined contracts and coin-margined contracts. These systems define the asset used as collateral for opening and maintaining positions. The choice between them affects settlement, profit calculation, risk exposure, and overall trading strategy. Understanding the mechanics behind each is essential for effective risk management and capital allocation.

What Are USDT-Margined Contracts?

USDT-margined contracts are futures contracts where the margin, profits, losses, and liquidation prices are all denominated in Tether (USDT), a stablecoin pegged to the U.S. dollar. This means that regardless of the underlying cryptocurrency being traded—such as BTC, ETH, or SOL—the value of the position is calculated and settled in USDT.

• The margin balance is held in USDT.
• Profits and losses (PnL) are realized in USDT.
• The liquidation price is calculated based on USDT value.
• All funding payments occur in USDT.

This structure provides price stability in terms of margining, as USDT’s value remains relatively constant. Traders who prefer to avoid exposure to crypto volatility in their margin account often choose USDT-margined contracts. For example, if you open a long position on BTC/USDT, your gains or losses will reflect changes in BTC’s price against USDT, but your margin account remains denominated in the stablecoin.

How Coin-Margined Contracts Work

In contrast, coin-margined contracts use the underlying cryptocurrency itself as the margin asset. For instance, if you trade a BTC/USD futures contract with coin margin, you must deposit BTC as collateral. All financial aspects—margin, PnL, and liquidation—are calculated in the base coin.

• The margin is posted in the cryptocurrency being traded (e.g., BTC).
• PnL is realized in the same cryptocurrency.
• Liquidation price is computed based on the BTC value of the position.
• Funding rates are paid in BTC.

This system introduces direct exposure to the price movement of the margined asset. If you hold a short position in BTC using BTC as margin, a rising BTC price not only increases your loss in USD terms but also depletes your BTC-denominated margin faster, increasing liquidation risk. Conversely, profits add more BTC to your account, which could be beneficial in a bullish market.

Key Differences in Risk and Exposure

The most significant distinction lies in risk exposure. With USDT-margined contracts, your risk is isolated to the price movement of the traded asset against USDT. Your margin value does not fluctuate with crypto market swings because USDT is stable.

However, in coin-margined contracts, you face dual exposure:

• Price movement of the futures contract.
• Volatility of the margin asset itself.

For example, if you margin a BTC futures contract with BTC and the price of BTC drops sharply:

• Your position may gain (if short), but
• The USD value of your BTC margin also declines, potentially affecting your overall equity.

This dual-layer risk makes coin-margined contracts more complex and suitable for experienced traders who understand cross-asset volatility impacts.

Settlement and Profit Calculation Examples

Let’s illustrate with a practical example.

Suppose you open a 1 BTC long position on a coin-margined BTC/USD futures contract at $30,000, using 1 BTC as margin. If the price rises to $33,000 and you close:

• Your profit is $3,000 worth of BTC.
• Since the contract is settled in BTC, your profit is 0.1 BTC (3,000 / 30,000).
• Your total BTC balance becomes 1.1 BTC.

Now, consider a USDT-margined BTC/USDT contract under the same conditions:

• You open a long position with, say, $3,000 USDT margin.
• At $33,000, your profit is $3,000 in USDT.
• Your USDT balance increases by $3,000.

The profit realization differs fundamentally: one in BTC, the other in stablecoin. This affects reinvestment strategies, tax reporting, and portfolio diversification.

Operational Steps for Selecting Margin Type on KuCoin

To trade either contract type on KuCoin, follow these steps:

• Log in to your KuCoin account and navigate to the Futures Trading section.
• Choose between USDT-Margined Futures and Coin-Margined Futures tabs.
• Select the desired trading pair (e.g., BTC/USDT or BTC/USD).
• Before placing an order, verify the margin type displayed at the top of the trading interface.
• Deposit the required margin asset:
  • For USDT-margined, deposit USDT into your Futures Wallet.
  • For coin-margined, deposit the base coin (e.g., BTC).
• Adjust leverage using the slider, keeping in mind that leverage settings are independent of margin type but affect liquidation risk.
• Place your order using limit, market, or conditional options.

Ensure your wallet contains sufficient balance in the correct asset. Attempting to trade a coin-margined contract without holding the base cryptocurrency will result in order rejection.

Liquidation Mechanics and Margin Ratio

Both contract types use a margin ratio to determine liquidation risk, but the calculation basis differs.

In USDT-margined contracts:

• The system calculates your equity in USDT.
• Maintenance margin and unrealized PnL are tracked in USDT.
• Liquidation occurs when equity falls below the maintenance threshold in USDT terms.

In coin-margined contracts:

• Equity is measured in the base coin’s value.
• Unrealized PnL and margin balance are in BTC (or other coin).
• The system checks if the BTC-denominated equity drops below required levels.

Because the margin asset’s market value fluctuates, coin-margined positions can face faster liquidation during high volatility, even if the futures price hasn’t moved dramatically.

Frequently Asked Questions

Can I switch from USDT-margined to coin-margined during an active trade?No. Once a position is opened under a specific margin type, it cannot be converted. You must close the current position and open a new one under the desired margin system.

Does funding rate differ between the two margin types?The funding rate mechanism is similar, but the settlement asset differs. USDT-margined contracts pay funding in USDT, while coin-margined contracts settle funding in the base cryptocurrency.

Which margin type is better for hedging spot holdings?If you hold BTC and want to hedge against price drops, coin-margined contracts are more effective. Shorting BTC with BTC as margin offsets both price and asset exposure, preserving your BTC-denominated net worth.

Is leverage limited differently between the two types?Leverage limits depend on the specific contract and market conditions, not the margin type. However, coin-margined contracts may have lower maximum leverage for certain pairs due to higher risk exposure.
