Just been reading about Takashi Kotegawa again—the guy who turned 13,600 dollars into 153 million. Most people know him as BNF, but his story is wild because it's not really about luck. It's about psychology.

So BNF was a broke college kid in the late 90s who literally just started watching stock market news and decided to trade. No finance degree, no rich family backing him. He worked odd jobs to fund his trading account and just... learned by doing. In 2005, he caught this insane Mizuho Securities error where they accidentally sold 610,000 J-Com Holdings shares at 1 yen instead of 610,000 yen per share. BNF saw it immediately and grabbed 7,100 shares. That single trade made him over 17 million dollars.

But here's what people miss—BNF also lost over 10 million in 2008 betting on US bank stocks during the housing crash. He broke his own rules. And that loss? That actually taught him more than his wins.

The real lesson from this trader isn't about finding the next 100x trade. It's about discipline. BNF treated trading like a game, not like his life depended on it. He said a 100k loss could feel better than a 6k gain depending on whether the trade was good or bad. The process mattered more than the outcome.

Now I'm watching crypto traders make the exact same mistakes BNF learned to avoid. They panic sell, they chase pumps, they get emotionally attached to positions. BNF's playbook still works—stay calm, have a plan, stick to markets you actually understand, and learn from losses instead of hiding from them.

If you want to build wealth through trading, the BNF trader approach isn't sexy but it works: discipline > emotion, process > outcome, learning > ego. That's it.
