I have been in this circle for many years, and since I entered in 2018, I haven't had a moment of peace. I personally experienced the entire process of Bitcoin soaring from $3,000 to $69,000, then dropping back to $16,000. At the craziest time, my 50,000 yuan principal grew to 7 million. To be honest, this wasn't luck-based gambling, but blood, sweat, and tears lessons learned through repeated falls with real money.

Today, I want to share 5 iron laws I’ve learned from the market, each repeatedly validated through practical experience. Some of these may overturn certain people's ideas, but it is precisely these "counterintuitive" rules that are key to survival.

**Rule 1: Distinguish between rapid rise with slow decline and rapid rise with flash crash**

When the market suddenly surges and then begins a slow correction, don’t panic and sell. This is usually the main force shaking out weak hands, deliberately oscillating to scare out indecisive retail investors. Once these people are gone, the real upward wave will come. But a completely different situation is when there's a 40% surge in one day, followed by a halving within hours—that’s a clear trap to lure in those chasing the high. In such extreme volatility, one word: run. Flash crashes after a rapid rise are never opportunities; they are scythes.

**Rule 2: Weak rebound and decreasing volume signals**

The coin price hits the bottom and then slowly pulls up. Many think it’s a good time to buy cheap. In reality, this weak rebound is nine times out of ten a false signal for the main force to offload. The final surge is designed to trap those who think they are "bottom-fishing experts."

Pay close attention to volume—continued high volume at high levels suggests room for further rise, so don’t rush to sell; but if volume suddenly shrinks at high levels, like a dead pond, then you must decisively exit. Continued volume at the top can sustain a little longer, but volume shrinking at the top is a true sign of a top.

**Rule 3: The authenticity of volume at the bottom is hard to judge**

When the price hits the bottom and suddenly a huge bullish candle appears with increased volume, don’t rush to chase. This is often a deliberate fake created by the main force. The real bottom signal is sustained high volume, not just one big bullish candle that excites you.
