Speculating on coins is not about D, but about monetizing knowledge. 1. Small funds should learn to 'wait', not 'full'. With a principal of 200,000, capturing 2-3 mainstream coins with an increase of over 30% is enough. In a bull market, the biggest fear is not missing out, but being fully invested and trapped. Those who dare to hold cash are the true hunters. 2. First practice 'not losing', then learn 'to earn'. The most expensive phrase in the crypto circle: 'I think this time is different.' People can only earn money within their understanding; start with a simulated account to practice, and once your mindset is stable, then move to a real account. Remember: losing once in a real account might mean there's no next time. 3. Good news = bad news? Beware of 'news traps'. On the day a significant piece of good news is announced, if the coin price has already surged, a high opening the next day is often a selling point. The manipulators know better than you how to use good news to profit from retail investors. 4. One thing to do before festivals: Analyze the data from the past 5 years; there is over a 70% chance of a drop in the week before a holiday. Either reduce your positions or hold cash for the holiday; don't go against the trend. 5. The core of medium to long-term investing: always keep some bullets. Don't exhaust all your chips at once. Sell in batches when prices rise and buy in batches when prices fall; cash flow is your moat. 6. For short-term trading, just look at two words: momentum. A sudden increase in trading volume + a breakout of resistance levels means follow up immediately; if it’s consolidating with shrinking volume, it's better to miss out than to make a mistake. 7. Is a sharp drop actually an opportunity? A slow decline indicates no one is buying, and it may continue to fall; a sharp drop with volume is often the last hit, and a rebound is imminent. 8. 90% of people fail at this point: 'I'll wait a bit longer to break even' is the biggest illusion. Stop losses should be quick, and profits should be slow; a 50% loss in principal requires a 100% gain to break even—are you sure you can do that? 9. Short-term trading tool: 15-minute KDJ. Buy on a golden cross, sell on a death cross, and use volume to filter out false signals. Suitable for those who don't have time to monitor the market. 10. Ultimate advice: less is more. Mastering 3-5 methods that can make money is enough. There are thousands of technical indicators, but those that can lead to stable profits are often just one or two. Why can some people turn 200,000 into 1,000,000 in 3 months? The key is not in technology, but in the secrets of position management. The harshest thing in the crypto world is not the market, but every opportunity you missed.
