After being in the circle for so many years, the most frequently asked question is—what leverage should I open for perpetual contracts?

My answer might be a bit harsh: **the key is not the leverage itself.**

Perpetual contracts have no expiration date, like a never-ending war. They indeed give you freedom and opportunities, but also hide traps. Leverage is essentially a double-edged sword—used correctly, it can accelerate wealth growth; used wrongly, it can directly wipe out your principal.

Many beginners think 30x is dangerous and 5x is safe, but this judgment is flawed. What is the real difference between 30x and 100x? It’s just the reaction space you have during market fluctuations—one is a few centimeters, the other a few millimeters. But ultimately, the outcome of winning or losing always depends on **position management and margin allocation**.

I’ve seen too many tragedies: using a few hundred dollars to leverage a position worth tens of thousands, only to be wiped out by a market fluctuation. The most regretful thing isn’t misjudging the direction, but seeing the right one and still being washed out by the oscillations in between. That feeling is truly nauseating.

**So risk control always comes first.**

I’ve summarized three iron rules for myself and want to share with you:

**First, always use isolated margin mode; never touch cross margin.** Keep risk within a single operation, don’t shake the foundation of your entire account. Even if you lose, it’s just a punch, not fatal.

**Second, strictly implement stop-loss; don’t think about stubbornly recovering.** Stop-loss isn’t shameful; it’s your life-saving talisman. Too many people lose everything because they can’t bear to cut losses on small amounts.

**Third, set rational goals.** For example, with a principal of 500 dollars, earning 50-100 dollars a day is already very good. This translates to a monthly return of 20%-40%, which is top-tier in the entire financial world. Don’t underestimate the power of compound interest; over time, it’s exponential growth.

Ultimately, leverage is like a magnifying glass—it amplifies gains but also amplifies your discipline and greed. True trading experts have long understood one principle: the main reason for liquidation is 90% psychological breakdown. A 100x leverage trader who strictly follows discipline is much safer than someone who operates recklessly at 5x every day.

**There’s no such thing as a "reasonable leverage," only leverage that matches your ability and discipline.** In the crypto world, leverage itself isn’t the enemy; out-of-control greed is.
