$ETH bought at 1600 to bottom out, and it kept rising to 4800. I still haven't sold. It's not about faith; frankly, it's a common human flaw—no one can really figure out where the top is.

When the price dropped from 2000 to 1400, the entire market was urging me to cut losses immediately; when it rebounded to 3000, the unanimous voice said it was just a dead cat bounce. Only when I withdrew my principal at 4200 did I realize: 99% of the market noise is really just psychological comfort for those missing out or trapped.

This experience is probably a mental journey every long-term holder goes through. When the market surges wildly, we fear a pullback, worried that the profits we've made will vanish, so we sell early; when prices plunge, we get scared and panic sell at the bottom. Amidst the market noise, the most expensive thing is never the price fluctuations themselves, but our nerves being repeatedly torn apart—same group of people shouting "this will go to zero" at the lows, then hyping "eternal bull market" at the highs.

The question is: in such an extremely volatile, noise-filled market environment, is there a way to both capture the long-term potential of assets and escape the vicious cycle of "selling too early" and "being trapped"?

There is indeed a solution. Instead of repeatedly struggling between "holding stubbornly" and "cutting losses quickly," it’s better to use a set of scientific financial tools to shift your position management from "gambling based on feelings" to "stabilized income based on rules." Moving from feeling-driven holdings to rule-driven profit management is essentially building an asset ark capable of crossing bull and bear markets. Once we accept the reality that precise timing is impossible, the smartest move isn’t to escape volatile assets but to add a layer of protection through financial instruments.
