USDT-margined vs Coin-margined Contracts

# USDT-margined vs Coin-margined Contracts

In perpetual contract trading, contracts can be divided into USDT-margined (USDT-settled) contracts and Coin-margined (Coin-settled) contracts according to the different settlement assets. These two types of contracts have significant differences in pricing units, profit and loss calculation, risk management, etc., and are applicable to different traders and market environments.

# Basic Differences

# USDT-margined Contracts

USDT-margined contracts use USDT (Tether) as the margin and settlement currency. In this type of contract, profits and losses are calculated and settled in USDT.

Key features:

  • Margin Currency: USDT is used as collateral, which is more stable than cryptocurrencies.
  • Profit/Loss Currency: All profits and losses are denominated in USDT.
  • Contract Value: The contract value is calculated in USDT (e.g., 1 BTC contract at $50,000 = 50,000 USDT).

# Coin-margined Contracts

Coin-margined contracts use the underlying cryptocurrency (such as BTC, ETH) as the margin and settlement currency. In this type of contract, profits and losses are calculated and settled in the underlying cryptocurrency.

Key features:

  • Margin Currency: The underlying cryptocurrency (like BTC or ETH) is used as collateral.
  • Profit/Loss Currency: All profits and losses are denominated in the underlying cryptocurrency.
  • Contract Value: The contract value is typically fixed in USD, but settled in the cryptocurrency (e.g., 1 BTC contract might represent $100 worth of BTC).

# Profit and Loss Calculation

# USDT-margined Contracts

In USDT-margined contracts, profit and loss are calculated in USDT, which is more straightforward and similar to traditional futures trading.

Profit/Loss Formula:

  • Long Position: (Exit Price - Entry Price) × Contract Size × Quantity
  • Short Position: (Entry Price - Exit Price) × Contract Size × Quantity

# Coin-margined Contracts

In Coin-margined contracts, profit and loss are calculated in the underlying cryptocurrency, making them "inverse contracts" because their value moves inversely to the price of the cryptocurrency.

Profit/Loss Formula:

  • Long Position: Contract Size × Quantity × (1/Entry Price - 1/Exit Price)
  • Short Position: Contract Size × Quantity × (1/Exit Price - 1/Entry Price)

# Risk and Margin Management

# USDT-margined Contracts

  • Risk Characteristic: When the price of the underlying asset increases, the value of long positions increases, while the value of short positions decreases.
  • Margin Requirement: When the price of the underlying asset increases, the margin requirement for short positions increases, while the margin requirement for long positions remains constant.

# Coin-margined Contracts

  • Risk Characteristic: When the price of the underlying asset increases, the margin value (in USD) increases but the required margin (in crypto) decreases for long positions, while it increases for short positions.
  • Margin Requirement: When the price of the underlying asset increases, the margin requirement (in crypto) for short positions increases, while the margin requirement for long positions decreases.

# Advantages of Different Contract Types

# When to Use USDT-margined Contracts

  • Market Bullishness: In a bullish market, traders holding long positions in USDT-margined contracts benefit from the increasing value of their positions without worrying about declining cryptocurrency holdings.
  • Simplicity: Profit and loss calculations are more intuitive, especially for beginners.
  • Stable Margin: Using a stablecoin like USDT as margin eliminates concerns about the fluctuating value of the collateral.

# When to Use Coin-margined Contracts

  • Market Bearishness: In a bearish market, traders with short positions in Coin-margined contracts can gain more cryptocurrency as prices fall.
  • Hedging: Cryptocurrency miners and long-term holders can hedge against price volatility without converting their holdings to stablecoins.
  • No Stablecoin Required: Traders can participate in leveraged trading without the need to convert their cryptocurrency to stablecoins.

# Conclusion

Both USDT-margined and Coin-margined contracts have their unique advantages and use cases. USDT-margined contracts offer simplicity and stability, making them suitable for traders who want to maximize their USD returns or those who don't want to worry about the changing value of their margin. Coin-margined contracts, on the other hand, are beneficial for traders who already hold cryptocurrencies and want to increase their cryptocurrency holdings, particularly in a bearish market. Understanding the differences between these contract types allows traders to choose the most appropriate one based on their trading strategy, risk tolerance, and market outlook.
