At three o'clock in the morning, the phone rang. At this time, the ringtone is usually not good news.

After the call connected, a hoarse and tense voice came from the other end: "Brother... my 50,000 U is gone." The voice was trembling.
He paused for a moment and added: "15 times, Ethereum long position... just retraced by 6 points."
My heart sank. I didn't need to look at the records to know what had happened: I had put all my assets on the line without any brakes.
After hanging up the phone, I could almost see the scene before my eyes: on an unknown road, he pressed the accelerator to the floor, but didn't install the brakes at all. A slight deviation in direction would mean certain death.
Many newcomers to the market harbor the same illusion in their hearts: "Only by going all in can one earn quickly." It seems that unless they push all their chips to the table, they are not worthy of the current market conditions.
But the reality is just the opposite. Full margin does not amplify your profits; it merely compresses your margin for error to zero.
The market does not need to crash; even a normal pullback could cause you to exit instantly due to a lack of maneuvering space.
This is not a defeat to judgment, but a defeat to oneself - from the very beginning, you left no way out for yourself.
I told him: "You didn't lose to the market changes; you lost to your own position."
A leverage of 15 times is not in itself a monster; what is terrifying is exhausting all your funds and hopes in a single bet.
A 6% fluctuation is just a breathing adjustment for those with a backup position; but for those who have gone all in, it often marks the end of the story.
It's like riding a motorcycle with the brakes taken off. The feeling of speeding down a straight road is certainly addictive, but any turn or even a small pebble is enough to make you completely lose control.
True trading wisdom lies not in how much you dare to bet, but in knowing how much to keep for yourself. After all, surviving is the only way to qualify to see tomorrow's market.
