A few days ago, a friend told me: "I check the charts every day, but I keep losing money. Should I just give up on crypto?"

My answer was straightforward: "It's not that you lack talent, you're just too greedy."

The longer you stay in the crypto market, the more you realize a harsh reality—

People holding full positions panic at the slightest dip; those sitting on the sidelines regret every upward move; only those who control their positions reasonably and set proper defenses can walk out with a smile.

I've been through it too. During the 2020 rally, watching the K-line chart was so steady it seemed unreal, I impulsively went all-in on long positions. Then came a big bearish candle, three consecutive stop-losses, and my account went from green to red, then black. That night, I truly understood what a "market textbook" is.

Since then, I completely changed my approach: no longer trying to predict the market, just strictly following the rules.

I set myself "three bottom lines":

**First, keep some room in your position.**

The heavier your position, the more your psychological defense collapses with slight market fluctuations. Always keep some ammunition; only then can you enter or exit at critical moments.

**Second, stop-loss is your life-saving device.**

A position without a stop-loss isn't trading; it's gambling. Instead of risking a mistake that could wipe out your account, it's wiser to accept small losses.

**Third, if you can't judge clearly, put down your phone.**

When market signals are unclear, I turn off my trading terminal to exercise or rest, rather than wasting time staring at the screen. When your mind is calm, your decisions will be rational.

This market has never been about who can make more money, but about who can endure losses. Position size is your shield, and stop-loss is your escape hatch—without either, you're not qualified to talk about "stable profits."

Many people fall into a misconception: thinking that watching the charts more frequently means catching more opportunities. In reality, it's quite the opposite. Overtrading is often driven by short-term fluctuations and emotions, leading to self-sabotage.

The top traders are not those who are always right, but those who can quickly correct mistakes and stay clear-headed amid market storms.

That’s the true quality of a winner.

Are you still being led by the market, or have you already learned to use discipline to control it?
