#加密安全须知 Trading Type Introduction: Why Do Contracts Always Liquidate?

It's not bad luck; it's that you fundamentally don't understand the essence of trading! This article, which condenses ten years of trading experience into low-risk principles, will completely overturn your understanding of contract trading—liquidation is never the market's fault, but a time bomb you set yourself.

Three Major Truths that Overturn Understanding

Leverage ≠ Risk: Position Size is the Lifeline

Using 1% position with 100x leverage, the actual risk is only equivalent to 1% of full margin in spot trading. A certain student operated ETH with 20x leverage, only investing 2% of the principal each time, and has three years with no liquidation record. Core formula: Actual risk = Leverage multiple × Position ratio.

Stop Loss ≠ Loss: The Ultimate Insurance for Accounts

In the 312 crash of 2024, 78% of liquidated accounts shared a common feature: losses exceeded 5% but still did not set stop losses. Professional traders' iron rule: a single loss must not exceed 2% of the principal, equivalent to setting a "circuit fuse" for the account.

Rolling Positions ≠ All-In: The Correct Approach to Compound Interest

Ladder Positioning Model: First position 10% for trial and error, using 10% of profits to increase positions. With a principal of 50,000, the initial position is 5,000 (10x leverage), and every time it profits 10%, 500 is added to the position. When BTC rises from 75,000 to 82,500, the total position only expands by 10%, but the safety margin increases by 30%.
