One thing that left a deep impression on me — someone made a profit of 1,000 with a 20,000 principal and was eager to exit, only to see the market take off afterward. He was crying and shouting, "Did I sell too early?"

Honestly, this isn't a market problem; it's simply being trapped by the "small money mindset."

I've walked this path myself. In the past, as soon as my account gained 3% or 5%, I’d get itchy and worry about profits being eaten away. The most painful part was never the moment of loss, but watching the coins I sold later surge by 40%, 70%, or even double. Conversely, when prices fell, I’d be especially "tough," holding on stubbornly without selling, only to be forced to cut losses when my face turned green from the losses.

Later, I understood a saying: earning small profits and losing big is the fate of beginners.

The turning point came when I heavily invested in a new coin, which evaporated 80% in just 7 days. That was when I finally understood what "dark horse" really means — actually a black hole.

Since then, I’ve focused on the most stupid, boring, and safest approach — buying mainstream coins that have been beaten down. Others say it’s lacking imagination, but I love its stability, like an old dog. Don’t guess the bottom; always start by throwing in some position to test the waters. If it stabilizes, add more; if not, treat it like buying a cup of milk tea and walk away.

Why not buy at the lowest point? There’s only one bottom, but a bunch of traps. Stepping wrong once means reflecting for half a year. When the trend comes, I add on dips, even if it’s 5% more expensive — I don’t care. The market only rewards those who are right about the direction, not those who buy the bottom and suffer from angina.

The last lesson I learned later — ride a wave up and take the principal back.

This trick is very counterintuitive, but it works so well. Take your principal plus some profits, leave the rest to grow freely. If it rises, you’re happy; if it falls, you can still sleep well. Over these years, I’ve seen too many people get rich quickly, lose everything, or even have their accounts wiped out. Truly stable profit-makers are those who look "zen," patient, and only eat big swings.
