These rules are lessons learned the hard way, paid for with real money. Understanding one can reduce losses by ten thousand; mastering three can make you outperform nine out of ten retail investors.

**First Rule: Don't rush to sell during a rapid rise and slow decline** When I used to play altcoins, I would panic when I saw a sharp increase followed by a slow decline. As a result, I would sell just before it doubled again. Later I realized: a gradual pullback after a high is a shakeout; genuine dump happens with a sudden large red candle after a sharp rise.

**Second Rule: Don't chase cheap prices during a rapid fall and slow rise** When ETH plummeted, I thought I had found a treasure and increased my position, trying to bottom fish. The result was being battered into doubt. When a large red candle drops and the price climbs slowly, it's often a bait set by the whales while running away, avoid it.

**Third Rule: Shrinking volume at the top is the most dangerous** When volume is high at a high level, there’s still a chance for another push, but if the volume shrinks, a turn is imminent. In 2021, when Dogecoin showed a volume decline at its top, I immediately sold all, and three days later it was halved.

**Fourth Rule: Continuous volume increase at the bottom is the real opportunity** Daily volume spikes are often traps, but the true bottom is characterized by low volume consolidation followed by continuous volume-driven rise. In 2022, when BTC dropped to $16,000 and showed this signal, I entered with full position and doubled my investment in half a year.

**Fifth Rule: Trading volume is more honest than candlesticks** Candlestick charts can be manipulated, but volume cannot deceive. I always analyze volume first, then price. When volume and price diverge, even beautiful candlesticks are just acting.

**Sixth Rule: The highest realm in the crypto world is "Three No’s"** No obsession—no stubborn holding; no greed—don’t chase highs; no fear—dare to bottom fish. I've seen too many fall into the traps of "cannot let go, can't help it, dare not move" over 8 years. Sticking to these three principles is more effective than anything else. Market conditions change, rules remain the same. Getting the rhythm right is more important than anything else.
