The crypto world is never a place where smart people stand out; instead, it is a training ground for those who practice self-discipline.

Looking at the recent on-chain data, it's clear. On December 18 alone, there were 118,000 liquidations across the network, resulting in a loss of $362 million, with a single ETH liquidation exceeding $10 million. Behind these stories, the basic script is the same: greed coupled with impulse.

A while ago, a fan came to me and said his account was down to only 3200U. He was repeatedly hit by market fluctuations and was being battered by leverage, making him feel a bit mentally unstable. But he didn't ask me "what coin to buy next"; instead, he switched his mindset: first survive, then make money.

Three months later, this guy's account nearly reached 30,000 U. The whole process wasn't about some chosen market trend, but rather the tedious execution day by day.

Breaking down his trading ledger actually points to one thing: using ironclad rules to combat human vulnerabilities.

**In terms of position design**, he divides the chips into three parts: 30% for day trading with strict stop-loss, never holding onto losing trades; 50% to follow the medium-term trend, only opening positions when the moving averages are still fluctuating; and the remaining 20% as a defensive cushion, which means doing nothing. This design directly eliminates the nightmare of "total liquidation at once."

**In the trading system**, he eliminated all complex indicators and focused on three things: the trend direction, whether the trading volume can keep up, and where the support level is. If any one condition is missing, he resolutely stays out of the market. Before entering a trade, he pre-sets the stop-loss line and take-profit ratio, withdrawing the principal when reaching a 50% profit, and using a trailing stop-loss for the remaining portion to follow the market trend.

The most ruthless part is that he has let go of the obsession with "chasing every market wave." He resolutely avoids following the crowd to buy the dip and does not increase his position to hold onto his trades.

The core of making money in the crypto world is actually quite simple: it’s not about how strong your predictive ability is, but rather about being able to persist in this game.

If you've recently been exhausted by contract leverage, ask yourself a question: Can your trading rules apply the brakes when your mind is heated?

Remember this phrase: The traders who ultimately live comfortably are always those "boring" people who can control their own hands.
