During the bull market in 2017, I followed the trend and bought $1,400 in ETH, and then I was deeply trapped, and my palms couldn't stop shaking when I cut meat. Looking back on this experience now, the costly tuition fee has taught me a simple but profound truth: in the world of cryptocurrency, the real value is not the skill of being familiar with candlestick charts, but being able to keep a clear head that is "not greedy".

I used to be the kind of novice who stared at price charts for up to 12 hours a day, and now I use the "three-layer position management method" for swing trading. On the day Bitcoin broke through 108,000, I reminded everyone in the discussion group "not to chase the high, set a profit-taking point around 105,000," because I observed that large on-chain addresses were gradually reducing their holdings; last week when Solana rose by 7%, I didn’t immediately issue a signal to build a position, but first studied the growth of the total locked value of DeFi protocols and confirmed the activity level of the ecosystem before leading investors in. Frankly speaking, the so-called "precise prediction" does not exist; these judgments are simply the result of organizing the various mistakes and lessons I have experienced over the past decade into investment insights.
