A buddy of mine once struggled quite badly in the crypto world, following the group to chase after Dogecoin, losing everything three times in two days, even losing his rent. Later, I gave him three ironclad trading rules, and within four months, his account skyrocketed to 2 million USD. But in the end, I still blocked him.

**Iron Rule 1: Divide and Conquer**
Split 800U into three parts for trading. Use 300U specifically for intraday trading, take profit at 5%, then exit; use another 300U to enter only at support levels; the remaining 200U is locked in as a "life-saving token." He initially thought this was too slow, but after seeing a colleague go all-in and get liquidated, he finally followed suit.

**Iron Rule 2: Main Uptrend, Eat Up, Sideways, Lie Flat**
In the crypto market, 70% of the time is just sideways consolidation. My approach is to go to the gym when the market is flat. He once tried to ambush ADA during a week of sideways movement at midnight, but I stopped him and said "wait for volume." The next day, a big bullish candle appeared, and we gained 18%. He gradually understood that sometimes "doing nothing" is much harder than frequent trading. Whenever profits exceed 15%, I force him to transfer the money to his bank card immediately.

**Iron Rule 3: System Lock**
Set stop-loss at 3% for automatic liquidation, and lock in profits over 8%. Once, he wanted to manually cancel his LTC stop-loss order, so I showed him a screenshot of his previous liquidation. That night, LTC plunged 12%, but he only lost 1%. Since then, he understood that knowing when to cut is a protective charm.

After his account reached 2 million USD, this guy started to get cocky. He joined signal groups, went all-in on MEME coins, and as a result, his principal was halved. He complained that if he had been fully invested earlier, he would already be worth millions. I pulled up a screenshot of him thanking me for risk control before, and suddenly realized—the real trap in the market is never the market itself, but those self-righteous gamblers.

Before blocking him, I finally said: "It's all about discipline, not luck! Arrogance will send you back to the beginning overnight!" The rule of the crypto world is this: discipline is the true life-saving charm.
