What are Coin-M perpetual futures?
Coin-M perpetual futures are crypto derivatives that are margined and settled in cryptocurrency, not in USDT. That means you post crypto (such as BTC or ETH) as collateral, and your PnL and settlement are denominated in that crypto. No USDT margin is required for Coin-M contracts.
Do Coin-M perpetual futures have an expiration date?
No. Coin-M perpetual contracts do not have an expiry or delivery date, so positions can remain open as long as margin requirements are met. To help keep the perpetual price anchored to the spot market, exchanges use a funding rate mechanism, where long and short traders periodically pay each other depending on market conditions.
What is the difference between Coin-M and USDT-M perpetual futures?
The main difference is the margin and settlement asset:
- Coin-M perpetuals: Margin, PnL, and settlement are in crypto. For example, a BTC-margined contract uses BTC collateral, and results are settled in BTC.
- USDT-M perpetuals: Margin and settlement are in USDT, so PnL is calculated and realized in USDT.
Coin-M is often preferred by users who want their trading results to be measured in crypto terms rather than stablecoin terms.
How does margin work in Coin-M futures?
To open a Coin-M position, you use the underlying crypto as margin. Your required margin depends on factors such as position size and leverage, and it typically includes:
- Initial margin: The amount needed to open the position
- Maintenance margin: The minimum amount needed to keep the position open
If your margin ratio worsens due to price movement and falls below requirements, the system may partially or fully liquidate the position to reduce the risk of a negative balance.

What happens if my margin becomes insufficient after opening a position?
If your margin level falls below the maintenance margin requirement due to price movement, the system may trigger liquidation to manage risk and prevent further losses. Any remaining balance (if applicable) will be credited back to your futures account.
To reduce liquidation risk, monitor your margin ratio and consider adding margin when appropriate.
How is the funding fee calculated for Coin-M perpetual futures?
Funding helps keep the perpetual price aligned with the spot market. Funding payments are exchanged between traders:
- If the funding rate is positive, longs pay shorts.
- If the funding rate is negative, shorts pay longs.
Funding rates update periodically and can be viewed directly on the trading interface.
