After years of trading cryptocurrencies, my biggest regret isn't losing money, but making millions of dollars and not selling.

During the 2020 market cycle, I heavily invested in one coin, and in just a few months, it skyrocketed many times over.
I would stare at my balance every day, smiling foolishly, even thinking about which neighborhood to buy a house in.
But I made the same mistake most people do—being too greedy.
I kept thinking it could keep rising, but the market turned around faster than anyone expected, and all the millions of profit I had made was wiped out.
After that, I truly understood that being able to buy is a disciple, but knowing when to sell makes you a master.
Later, I set strict rules for myself.
First, take profits in stages.
When it reaches the target, first recover the principal, then lock in the profit, and leave the remaining position to the trend, not expecting to sell at the very top.
Second, set stop-losses in advance.
If losses exceed expectations, exit immediately.
When the market is out of control, execution is more important than judgment.
Third, no longer chase the last leg.
I don’t want the head of the fish, nor do I fight for the tail—only take the most stable middle trend.
