Yesterday, I saw a certain coin go from 0.3 to 2 in one shot—truly amazing. I'm also lurking on RVV; the increase once surged to +195%. But what happened? I couldn't bear to sell.

Always this problem—thinking that the coins I hold might also take off someday. Reality slapped me in the face: it only rose less than 20% and then fell back to the starting point, causing my account to shrink instantly from the high.

Later, I thought about it and realized a few principles about trading:

First, don't be greedy at both ends. Using 10x leverage to catch a 20% swing is already a top-tier move. Waiting for tenfold gains before selling isn't greed—it's suicide.

Second, having many tools is useless. No matter how powerful AI or how high the win rate, if you don't know when to take profits, the numbers on the paper will always be just numbers. Wealth on paper is just that.

Finally, learn to be respectful. Just like the recent LIGHT surge a couple of days ago, many people were blinded by the rush. True experts know when to run and won't let greed bury themselves alive.

There is no predetermined ending in trading; only a clear understanding of the market and discipline for oneself. Next time, I will only take action when I see the right opportunity and will take profits when it's good.
