If this is your first experience with a bull market, these points are particularly important:

1. Every significant drop in a bull market is an opportunity to get in, especially around the New Year, when there is usually a pullback, making it a good time to increase your holdings.

2. Do not frequently change coins, especially when the coins you hold have not yet risen; it's best to hold patiently.

3. Do not put all your money into one coin; diversify your investments, pay attention to different popular sectors, and focus on leading coins.

4. Lock in a portion of your profits in a timely manner, and let the rest continue to grow. After a sharp drop, add to your holdings to seize low-price opportunities.
