Many people think that trading cryptocurrencies is just about luck, but that's not the case. The pitfalls I've stepped into and the money I've made over the years can be summarized into a simple logic—sounds naive, but following it can gradually make you wealthy.

First, let's talk about the trading approach for strong coins. Once a strong coin has been falling for 9 consecutive days from a high level, don't hesitate—timely follow-up is wise. Conversely, any coin that rises for two days in a row should be sold immediately. What about after a gain of over 7%? If it surges again the next day, just stay on the sidelines and don't rush to chase. For those previously big bullish coins, wait until the trend is completely over before considering to enter, otherwise it's easy to get caught holding the bag.

How to handle coins with calm volatility? If there's no movement for three days in a row, wait another three days and see. If there's still no change, consider switching positions. This is proactive rather than passively wasting time. There's also a very practical rule: if you can't even recover your cost price the next day, it's time to cut your losses decisively. This helps you stop-loss effortlessly.

There's an interesting pattern in the top gainers—"Three must have, five must have, seven must have." Coins that rise for two consecutive days should be bought on dips, and by the fifth day, it's usually a good selling point. Don't be greedy and try to eat the last piece of meat.

Trading volume is considered the soul in the crypto world. When the price consolidates at a low level and suddenly breaks out with high volume, pay attention. But if high volume appears at a high level with stagnation, that's a danger signal—must exit decisively. Good volume-price coordination helps avoid detours.

When choosing coins, only look at those with an upward trend, maximizing success rate and saving effort. In the short term, a 3-day moving average turning upward is a signal. For mid-term, a 30-day moving average turning upward indicates a genuine mid-term rally. An 80-day moving average turning upward means entering the main upward wave. What about a 120-day moving average turning upward? That's a long-term upward trend, and you can hold your position with relative confidence.

Small funds in the crypto space are not without opportunities. The key is to master methods, stay rational, strictly follow strategies, and be patient. Opportunities will come, but only if you live long enough and keep a steady mindset.

A heartfelt final word: if you don't have a stable income, don't trade full-time, and definitely don't borrow money to trade. Losses then can be devastating, and regrets come too late. Trading is a long-term game—don't get yourself stuck in a dead end.
