Six iron laws of blood and tears, understanding one can save you 100,000 in tuition fees, doing three can crush 90% of retail investors:

1. Don't panic sell when there's a sharp rise and slow decline: A sharp rise followed by a slow decline is often a washout, shaking off those who can't hold; the 'guillotine' after a surge is the bait-and-switch trap, stay alert.

2. Don't be trigger-happy during a sharp drop and slow rebound: A sharp drop followed by a slow rise is often the dealer unloading stocks; don't think about catching the bottom, the last wave of false rebounds is designed to trap the self-righteous.

3. Observe when there's volume at high levels, run quickly when there's dead volume at high levels: Continuous volume increase during a surge may indicate further gains; if volume is low at high levels with no new funds entering, a crash is imminent.

4. Don't rush during unusual movements at the bottom, continuous volume increase is the signal: A sudden surge in volume after a significant drop may be a false signal; continuous volume increase after a period of low volume is the real accumulation by the dealer.

5. Trading cryptocurrencies is about trading people's hearts, volume comes before price: Analyzing K-lines is essentially analyzing emotions, trading volume is a mirror of emotions, and price is merely driven by emotions.

6. 'Nothing' is the highest state: No attachments allow you to wait for opportunities, no greed prevents you from chasing highs, and no fear gives you the courage to act at low levels—this is the top trading mindset, which requires enough toughness to master.

Opportunities in the cryptocurrency world are never lacking, what’s missing are people with high awareness and execution capability!
