Differences Between USDT-Settled and Coin-Settled Perpetual Contracts

In perpetual futures trading, contracts are generally divided into two types: USDT-settled perpetual contracts (USDT-M) and coin-settled perpetual contracts (COIN-M).

The core difference lies in the margin and settlement assets, which leads to variations in risk structure and suitable use cases.


I. Different Settlement and Margin Assets

1) USDT-Settled Perpetual Contracts (USDT-M)

  • Use USDT as margin and settlement asset.

  • Profit and loss (PnL) and funding rates are settled in USDT.

  • Margin value remains relatively stable and is unaffected by coin price fluctuations.

Features:

  • Intuitive and easy-to-calculate returns.

  • Relatively lower volatility.

  • Suitable for most traders, especially beginners.

2) Coin-Settled Perpetual Contracts (COIN-M)

  • Use the corresponding cryptocurrency (e.g., BTC, ETH) as margin and settlement asset.

  • Profit and loss and funding rates are settled in that cryptocurrency.

  • Margin value fluctuates with the coin price.

Features:

  • Allows accumulation of more of the underlying cryptocurrency through trading.

  • Returns can be significantly amplified during bull markets.

  • Requires higher risk management skills.

Coin-Settled Perpetual Contracts

  • More suitable for medium-to-long-term strategies.

  • Often used in bull markets to "earn coins through contracts."

  • Higher entry barriers and require deeper risk understanding.


V. Summary

  • Coin-settled perpetuals: Suitable for long-term holders and traders looking to accumulate cryptocurrency-denominated assets.

It is recommended that beginners start with USDT-settled perpetual contracts and only consider coin-settled contracts after fully understanding leverage and risk mechanisms, based on their specific needs.
