Are there still people "carving a boat to seek a sword" in the four-year cycle?

Before 20年312, the price was very low, everyone thought it was the bottom and waited for the bull market, going all-in with leverage, but then the 312 black swan happened, and everyone closed their positions.
Before the 24年 halving, many people were waiting for a black swan, but the bull market started early, and many missed out.

You can believe that ups and downs have cycles,
but history is hard to use directly as an objective basis for your decisions.
History will only tell you
that no matter how awesome your system is, there will be times of failure.
You were wrong.
