These iron rules provide valuable references for newcomers in the cryptocurrency world! Here are your top ten iron rules:

1. Bull market popular coins fall the fastest: Those coins that are highly speculated in the market, due to serious price manipulation, often suffer the most when the bubble bursts. Popular coins are like balloons; the more people chase them, the more dangerous they become.

2. Altcoin patterns are fixed: The trends of altcoins often involve a sharp drop followed by a slow rise, harvesting investors in different ways. Therefore, be mentally prepared and treat them with caution.

3. The long-term market trend is upward: Although there are frequent fluctuations in the short term, looking at the longer term, the overall market shows a slow upward trend.

4. Potential coins are often overlooked: Truly promising coins are often ignored at the bottom and rise quietly, such as C98 and LEVER.

5. New coins listed require caution: Newly listed coins on exchanges can easily fall into traps of extreme price swings, usually set by market makers, making them vulnerable to being 'cut'.

6. Price fluctuations are common: It's common to buy and immediately see a drop, or sell and see a rise; one must train their mindset to adapt to this volatility.

7. A sharp rebound doesn't necessarily indicate potential: Coins that rebound sharply are mostly driven by speculative trading, while potential coins tend to have more stable fluctuations; don’t be misled by appearances.

8. Beware of sudden pullbacks: If there's a brief rise after buying followed by a sudden pullback, it might indicate that the market maker is offloading, and one should be wary of being 'cut'.

9. Coins that explode later: In the second half of a bull market, coins that performed mediocrely earlier often surge several times, like marathon runners who explode in the final stretch.

10. Coins that have consolidated for months have opportunities: In a bull market, coins that can consolidate for several months after increasing several times often brew the next wave of explosion, worth close attention.

Summary: If your operations are not going well and you feel confused, remember two things: take decisive action; stay online and respond promptly to market information.

These suggestions provide investors with operational direction and psychological support, helping to maintain calm and decisiveness in a volatile market.
