Discipline is the real life-saving straw.

Once a fan approached me, his account only had 3000U left. He chuckled bitterly as he recounted this blood-and-tears story—over twenty thousand in principal, nearly wiped out after a series of reckless operations. Chasing gains, cutting losses, leverage liquidations, missing out on FOMO—he had jumped into all these pits. My advice to him was straightforward: "Change your approach."

I didn't give any profound theories, just a set of hard rules: no single position exceeding 30% of total funds; take profits at 10% to 15%; cut losses immediately if they exceed 4%; avoid trading unclear trends altogether. When he first started implementing these, he felt pretty awkward, reviewing his trades every day. After three months, he messaged me saying his account grew from 3000U to nearly 40,000U. His words were: "It's really not luck, discipline brought me back."

**Position sizing determines life or death**

I have one strict rule: no single position should exceed 30% of total funds. Sounds conservative? But it's not about maximizing profits; it's about staying alive.

The data is sobering—90% of liquidation cases stem from poor risk management. No matter how correct your market direction judgment is, if your position is too heavy, a small fluctuation can wipe you out.

My approach is to split the money into three parts: 10% for aggressive trading to test the waters; 20% for dollar-cost averaging into mainstream coins for long-term holding; and the remaining 70% parked in low-risk, stable financial products. Even if the aggressive position loses everything, the account won't be wiped out.

**Take profit and cut losses are psychological games**

Taking profits at 10%-15% is the hardest part. Human nature always wants to greed a little more, but often that results in giving back what was gained. Cutting losses within 4% is also difficult; there's always a feeling that it might rebound.

In fact, these are all psychological barriers. Truly long-lasting traders never gamble against the market.
