Capture market signals such as social media topic growth rate, growth of ecological interaction address number, and mainstream platform search index; 2. Verify fundamentals such as team background, rationality of token model, and distribution of on-chain coin address; 3. Combined with technical indicators such as weekly breakthroughs in key resistance levels, trading volume exceeds 3 times per month, and RSI is in the 40-60 range; 4. Establish a continuous tracking mechanism for data dashboard monitoring, project milestone reminders and development progress review, and beware of traps such as abnormal promotion, liquidity pool imbalance and lack of technical documents, and optimize decision-making through small-scale testing, establishing tracking lists and retaining 20% cash reserves, and ultimately relying on in-depth research rather than chasing hot spots to achieve long-term success.
