Volume is a thermometer, K-line is report card, but sentiment is the true steering wheel.

I have been in the crypto world for over eight years. I have seen stories of overnight riches, and also witnessed tragedies of accounts being wiped out instantly. Successful traders are like the longevity stars in the market—there is no shortage of fleeting celebrities in the crypto space, but what’s truly rare are the veterans who can survive long-term.

A friend of mine turned 30,000 U into 58 million U over four years. When asked about his secret? He smiled and said, there’s no such thing as a genius, just a set of clumsy methods persisted with, every loss turned into a lesson. The six rules he summarized each come at a real cost.

**First Rule: Rapid rise and slow decline is a sign of accumulation**

When the price suddenly surges rapidly, then begins to decline slowly—this is 80% likely the main force accumulating. Most retail investors get scared and sell, only for the price to soar immediately afterward. What’s the key? Look at volume. True upward movement will be accompanied by continuous volume release, while during slow declines, trading volume gradually diminishes, indicating the controllers haven’t left—they’re just shaking out weak hands. My experience is, if the pullback after a rapid rise doesn’t exceed half of the gain, and the key support levels hold, then hold tight. Market makers can create panic, but as long as you see through their tricks, you won’t be easily shaken out.

**Second Rule: A waterfall after volume surge is mostly a trap to lure more buyers**

A common trap: after a volume-driven rally, the price suddenly crashes—that’s a trap set by the main force. They first create a false impression of an uptrend to attract retail chasing high, then take the opportunity to offload. The way to break this pattern is to observe the persistence of volume. Genuine upward trends will sustain increased volume over a longer period; while false signals of volume surge tend to vanish quickly, followed immediately by a sharp decline in volume—that’s a sign of the main force changing hands.
