Recently, I’ve heard several heartbreaking stories in a row. Someone got liquidated after chasing ETH to the moon, someone couldn’t bear to cut their BTC and ended up losing everything, and someone spent 8,888 yuan on a "Godly Trading System" only to lose half a year's salary in three days. To be honest, the most widespread lie in the crypto market isn’t "Bitcoin can reach 1 million," but "buy a system and earn passive income."

Having been in this circle for 8 years, I’ve seen too many people treat trading systems as a lifeline. They think that as long as they have rules and frameworks, they can avoid all pitfalls and make easy money. But I have to say something blunt: the true value of a trading system isn’t to make you get rich overnight, but to keep you alive.

What is a trading system? In simple terms, it’s about standardizing your trading logic—when to enter, when to exit, how large each position should be, how much to cut losses when the market drops. Basically, it’s putting a "brake" on your greed and fear. My own system clearly states: no single BTC position should exceed 5% of total funds, and if a key support level is hit, stop-loss unconditionally within 3 seconds. Even if I’m optimistic about the market afterward, I follow this rule.

Why can’t you expect it to make money directly? Because most systems on the market are based on historical data. Using last year’s weather forecast to predict this year’s floods—how reliable is that? I did an experiment last year, backtesting 10 popular systems on the 2022-2023 market data, and their win rates were over 60%. But in real trading over a month, most of them failed outright.

That’s the reality. A true trading system is about helping you survive longer and stay steady amid market fluctuations, so you don’t lose all your hard-earned money in a couple of mistakes. That’s all there is to it.
