1. When the market crashes and your coin only slightly drops, it indicates that there are market makers protecting the price, preventing it from falling further. Such coins can be held with confidence, and there will surely be rewards in the future.

2. For beginners trading coins, there's a simple and direct method: for short-term trading, look at the 5-day moving average. As long as the coin price is above the 5-day line, hold it; if it falls below, sell it. For medium-term trading, look at the 20-day moving average. If the coin price is above the 20-day line, hold it; if it falls below, exit. The best method is the one that suits you, and the key is to stick to it.

3. If the main upward trend of the coin price has formed and there is no obvious increase in volume, decisively buy. Continue to hold during volume increases, and hold even if there is a decline in volume as long as the trend is not broken; if there is a volume decrease and the trend is broken, quickly reduce your position.

4. After buying short-term, if the coin price has not moved within three days, sell if possible. If the price drops after buying and losses reach 5%, stop loss unconditionally.

5. If a coin has dropped 50% from a high position and has fallen for 8 consecutive days, it indicates that it has entered an oversold state, and a rebound may occur at any time, so you may consider following up.

6. When trading coins, choose leading coins, as they rise the most when going up and resist the most when going down. Don’t buy just because the price has dropped significantly, and don’t avoid buying just because it has risen a lot. When trading leading coins, the most important thing is to buy at a high price and sell at an even higher price.

7. Trade in accordance with the trend; the buying price is not always better when it's lower, but rather when it's more suitable. Don't easily call a bottom during declines, and give up on coins that perform poorly. The trend is the most important.

8. Don’t let temporary profits cloud your judgment; understand that consistent profit is the hardest. Review seriously to see if your profits are due to luck or skill. Establishing a stable trading system that suits you is the key to sustained profits.

9. Do not force trades without sufficient confidence. Being in cash is also a strategy; learning to be in cash is important. The first consideration in trading should be capital preservation, not profit. It's not about the frequency of trading, but the success rate.
