# Margin

AstherusEX offers USDT-margined perpetual contracts with a unique Multi-Asset Mode. This mode unlocks several benefits:

* Trade with Flexibility: Use a variety of cryptocurrencies as collateral (including restaked assets) for your USDT-margined Futures trades.
* Efficient Capital Allocation: Your margin gets shared across all open positions, maximizing its utilization.
* Profitable Setoff: Profits from winning positions can automatically offset losses in losing ones, optimizing your margin usage.
* Simplified Monitoring: The margin balance reflects your net profit or loss (PnL) across all positions, providing a clear view of your overall exposure.

*Please note that Multi-Assets Mode only supports Cross Margin Mode.*\

**Automatic exchange mechanism**

To ensure your trading continues uninterrupted, the Multi-Assets Mode offers automatic balance management. Here's how it works:

* Threshold-based exchange: If the balance of a specific asset falls below a set threshold, other assets in your USDT Futures wallet will be automatically converted to cover the deficit.
* Matching engine efficiency: This conversion is handled by the platform's matching engine, ensuring a smooth and efficient process.
* Zero commission fees: AstherusEX doesn't charge any commission for this automatic exchange service.

This automatic exchange mechanism will help you balance your positions and increase capital utilization.
