Before a real bull market begins, the market usually goes through a consolidation phase, where the goal of the operators is to shake out retail investors' holdings through repeated fluctuations.
For example, when the price of Ethereum rises to 3700, if you do not take profits in time, you may encounter a sharp decline that makes you regret it.
After the market warms up and rises to 3700 again, would you consider selling? If you can resist selling, then there will be another significant drop to 3300; would you feel regret at that moment? If the price rises back to 3700 again, would you choose to take profits?
I guess most retail investors would choose to take profits. Even if retail investors hold on, as the market fluctuates again, their holdings will eventually be completely shaken out.
The operators will use big data analysis, and only after the retail investors' holdings have been shaken out will they start the market. This is why frequently trading retail investors often lose money, because the operators have deeply understood the weaknesses of human nature.
