To be honest, in the crypto world over these years, Brother Cat's biggest pain isn't the losses, but the nearly complete reversal of dozens of times the profit on paper, leaving only a tiny bit—those kinds of despair, people who haven't experienced it truly don't understand.

In the 2017 bull market, Brother Cat heavily invested in ADA, with a cost of $0.03, rising all the way above $1, multiplying the paper profit by over thirty times.
Back then, I was floating on cloud nine, always feeling that selling early was a loss, determined to sell at the highest point.
As a result, the market suddenly reversed, profits plummeted, and I clung to hope, holding on stubbornly, only to see dozens of times the profit go to waste.
That night, I completely woke up: in the crypto world, just knowing how to buy is only the entry; understanding how to take profits and cut losses, and knowing when to exit is the real skill!
Many people fall for the trap of "greed," not leaving after making money, and eventually turning gains into losses.
Later, I simplified my trading: first think about exiting, then consider entering;
take some profits when it rises, then gradually reduce positions to lock in gains;
leave a small core position with a set stop-loss, risking at most 5% per trade, and exit when the time is right.
Not aiming to buy at the lowest or sell at the highest, but eating steadily in the middle range, is the way to survive long-term in the crypto world.
