#数字资产市场动态 The trajectory of that one ETH late at night that year still gives me goosebumps when I think about it.

It shot up instantly from $1800 to $2400. I clenched my neck and threw in $3000 U, and the moment I confirmed the purchase, my whole heart was dancing with the charts. Over seven days, my account’s unrealized profit approached $6000 U. I immediately turned off all alerts, with only one voice in my head: It’s not too late to sell if it reaches $3000. When my friends organized a dinner, I was still staring at the K-line chart, and the first thing I did when I woke up in the middle of the night was to take out my phone to check the market. At that time, I didn’t even consider the numbers in my account— to me, that was already money in my pocket.

Then the Federal Reserve announced a rate hike, and ETH quickly dropped back to $1900 in no time, and the unrealized profit evaporated just like that. The hardest part wasn’t losing money, but watching the profits disappear right before my eyes. Holding on until the account hit zero and returned to the initial $3000 U, I sat in the corner eating cold wontons, finally realizing: no coin can withstand human greed.

I paid this tuition more than once. I made three times the profit on that NFT wave but couldn’t bear to sell, only to end up cutting losses in the end; I kept my stop-loss off during BTC swing trading, determined to hold on no matter what, only to get cut in half. Blood and tears accumulated to a certain point, and I finally figured out some real life-saving rules.

First: Never put all your chips on one card. Keep BTC in a cold wallet, allocate some bullets to ETH and SOL, and always maintain cash positions—full positions should never even be in the dictionary.

Second: As soon as you see profit on the screen, take it out immediately. The numbers on the screen are not money; the money in your wallet counts. It sounds simple, but very few can resist the temptation.

Third: Setting a stop-loss is not giving up; it’s self-rescue. Set it when a single loss reaches 2% or a monthly drawdown hits 5%. Recognize small mistakes early, and big problems won’t come knocking.

The crypto world is never short of wealth myths; what’s truly lacking is that clear-headed self-control.
