If you want to make money in the cryptocurrency world, you must remember these six iron rules: If you want to make money in the cryptocurrency world, you must remember these six iron rules:

1. You should divide your money into five parts, and only use one-fifth for trading at a time. If you lose 10%, leave immediately. Doing the math, even if you lose five times in a row, you'll only lose one-tenth of your total capital, which won't hurt too much.

2. You must follow the market trends and not go against them. When the market is down, a rebound could be a trap; when the market is up, a pullback might be a good opportunity to make money.

3. Never chase coins that have already surged; they have risen too high and could fall at any moment.

4. You need to learn to read the MACD indicator, as it can help you find the best timing for entry. When the DIF and DEA lines cross below the zero axis and then cross above it, that’s a good buying opportunity; if they cross above the zero axis and then head down, that’s a signal to sell.

5. Remember, never add to your position when you are losing money; add to your position when you are making money. You need to pay attention to the volume-price relationship. If the coin price breaks out with volume when it's low, it may go up; if it doesn't rise when the volume is high, then you should run. When selecting coins, choose those with good trends and value.

6. Review your trades every week, see what you did well and what you did poorly, and adjust your strategy in time.

These six iron rules are lessons I learned through my own painful experiences. If you follow them, you will definitely thrive in the cryptocurrency world!
