One day in the crypto world is like ten years in reality
Core Mechanisms of Contract Trading
Contract Type Comparison
Perpetual Contracts: No expiration date, anchored to spot prices through a funding rate mechanism, suitable for high-frequency traders34
Delivery Contracts: Fixed expiration date (e.g., end of the quarter), commonly used by miners for hedging, prone to significant price fluctuations before delivery1
U-based and Coin-based: USDT pricing offers more intuitive risk, while BTC as collateral has anti-inflation characteristics4
Leverage Operation Principles
Leverage is essentially a capital amplifier (e.g., using 10x leverage to control a position of 100,000 with 10,000), but high leverage significantly reduces fault tolerance23
Calculation Formula: Margin = Position Value / (Leverage × Latest Price), maintenance margin rate typically needs to be above 0.5%4
