Sharp pull followed by slow decline is mostly shaking out weak hands—don't panic and sell at a loss. The real top often arrives with sudden volume surge followed by a sharp crash that traps late buyers. Stay calm and don't get tempted.​

Second rule: Fast decline, slow rise might indicate the dealer is quietly offloading.
Slow rebound after a flash crash—don't assume it's a bargain hunt opportunity, it could be the final knife. Be careful not to hold the mindset "it's dropped so much already, how much lower can it go?"—you could take a hard fall.​

Third rule: High volume at the top doesn't necessarily mean the end; lack of volume is what should alarm you. High volume at resistance might allow another surge, but once volume dries up, a crash signal is coming.​

Fourth rule: Don't rush on volume at the bottom—sustained volume is reliable. Single volume spikes are often "bait" to lure retail traders; only if volume keeps increasing after a few days of consolidation is it a real accumulation opportunity.​

Fifth rule: Trading crypto is essentially trading human psychology, and all psychology is hidden in volume. K-lines are just results; the key to understanding the market is trading volume: low volume means nobody's interested, high volume means capital is flowing in.​

Sixth rule: "Non-attachment" is the real skill. Without obsession, hold cash when you should, strike decisively when opportunities arise, avoid greed. Staying calm is how you survive long-term in crypto.​

These six methods are simple yet solid—many people love frequent trading, but I'd say the safest path is to take it slow, execute each trade well, and stay patient and composed.​
