I've seen a quite interesting case, which you might find exaggerated.

This guy used to trade contracts, a typical all-in type. He gets excited whenever he sees the market and can't wait to put all his bullets in at once. What happened? He ended up losing so much that he doubted his life and ultimately deleted the app, out of sight, out of mind.

The turning point happened at the beginning of this year. He re-entered the scene, but this time his attitude had completely changed. The first thing he said to me was: "I want to learn something reliable, no more messing around."

I replied to him at that time: "First, let's get the matter of 'no loss' straightened out, and the rest can come slowly."

Not teaching any profound techniques, just focusing on three points: don't go all in, set a good stop loss, and take out a portion of your profits. Sounds simple, right? But this time he really took it to heart, following the rules for every trade.

Gradually, the account curve stabilized, and the mindset followed suit.

The most impressive was the $ZEC trade — opened a short near 530, exited at 380, made 46,080U in a single transaction, with a return of over 425%. It wasn't based on guesswork; it was waiting for the opportunity.

He currently has 8.84 million U in his account. When asked about his secret? Just two words: follow the rules. Luck is unreliable.
