After eight years in crypto trading, the most common question I've seen is—"How much leverage should I use for perpetual contracts?" But honestly, this question is asked the wrong way.

Perpetual contracts are like a battlefield that never closes. It's easy to enter, and easy to exit, but not many can come out alive. Leverage is a double-edged sword: used correctly, it's a rocket booster; used wrongly, it's a meat grinder.

Many beginners think that 30x and 100x leverage are vastly different, as if low leverage is stable and high leverage is explosive. But in reality? The difference is the market's response time—30x is like a few centimeters, 100x is like a few millimeters. The key isn't the multiple itself, but how you use your position and margin to bear the risk. Using a few hundred dollars to control a position worth tens of thousands, even small fluctuations can wipe you out instantly. The most painful part isn't just misjudging the direction, but correctly predicting it and still getting shaken out by market jitters.

So what is the real core? It’s four words: **Risk Control**. Keep these bottom lines in mind:

**First, the isolated margin rule**—risk must be locked within each individual trade, never full margin. The worst outcome is losing that one trade’s capital, without affecting the entire account.

**Second, stop-loss must be executed**—don’t rely on a rebound. Many get wiped out because they "hold the position," enduring trade after trade, until finally getting liquidated.

**Third, set small daily goals**—earning 50 to 100 dollars daily on 500 dollars of capital may seem small? But earning 20%-40% per month is an excellent result in the financial markets. Compound interest is built this way.

Leverage, at its core, is just a magnifying glass. It not only amplifies gains but also your discipline, greed, and execution. True traders know: liquidation isn’t the market’s fault, it’s a mindset issue. Being able to control losses with discipline a hundred times better is always safer than risking five times without discipline.

So there’s no such thing as an absolutely "reasonable" multiple—only whether it matches your understanding and ability. Leverage itself isn’t a demon—**greed is**.
