In the years of playing in the cryptocurrency space, here are some personal experiences summarized:

1. In a bull market, the more popular coins (often accompanied by high control) drop faster.

2. True potential coins and bottom coins are rarely promoted; only a small portion of people occasionally mention them at the bottom.

3. The trend of cryptocurrencies, looking at the big picture, is always a smooth curve.

4. The methods used by altcoin promoters to pump prices are generally similar, usually involving a sharp drop followed by a slow rise.

5. New coins on exchanges that experience a sharp rise followed by a sharp drop should be avoided.

6. Buying leads to drops while selling leads to rises; this is quite normal. If you can't handle this level of volatility, you should consider your mindset.

7. When you buy and the price not only doesn't drop but rises, and then suddenly starts to correct after you've made a profit of 5%-20%, it indicates that this coin is about to be harvested.

8. The coins that rebound the most are often not the potential coins, but rather the ones that attract inexperienced investors.

9. In a bull market, some potential coins may perform mediocre in the first half but often see several times the increase in the second half.

10. In a bull market, if a coin has experienced several times the increase and can still remain stagnant for months, it is likely a potential coin, like the puppies concept associated with Elon Musk in the primary market.
