Trading in the crypto circle, understanding the main force's movements is more important than anything else. I have summarized 5 practical rules, which are based on experience gained through countless oscillations.

**Rapid rise and slow fall = accumulation**. The market soars quickly, but the decline is sluggish, which usually indicates that the big players are quietly accumulating chips and preparing ammunition for the next surge. Conversely, **fast fall and slow rise = distribution**. A sharp drop combined with a sluggish rebound suggests that the main force is gradually cashing out, and market bearishness is spreading.

The top area tests psychological resilience the most. **High volume but no selling, run quickly if there's no volume**—a sudden increase in trading volume at the top may indicate potential for further push; but if the volume shrinks and no one is taking over, profits should be protected. The bottom requires more patience. **High volume at the bottom doesn't mean rush to buy; sustained volume is the signal to act**. A sudden spike in volume at the bottom often indicates a trap for more gains, but if funds keep flowing in and volume continues to rise, it shows genuine support is being built.

The most critical point: **Price follows sentiment, and volume reflects consensus**. Market fluctuations are essentially a game of emotions, and volume is the most authentic record of this game—it reflects real fund flows and the true attitude of participants.
