Discover a crucial rule that is important for both Cryptocurrency Trading and stock trading:

We need to establish a perception of market sentiment under the premise of receiving market information with "granularity stability."

Not looking at the market for a while vs staring at it for more than ten hours a day, the feeling of market sentiment is completely different.

Staring at it every day can easily lead to getting caught up in the self-indulgence, overestimating emotions;
Not paying attention to the market can easily lead to missing trading opportunities.
For a while, I won't watch the market at all, but when the bull market comes, I'll be staring at it every day. It's okay, it's you who will be cut off.

What we need to do is to slowly build our perception of market sentiment by "maintaining an appropriate frequency and stable information intake", thereby achieving "when others are greedy, I am fearful; when others are fearful, I am greedy."
