Recently, the trading community has been buzzing again about BNF (Takashi Kotegawa). Why is he attracting so much attention? I think it's because his legendary success still serves as a valuable reference in today’s market environment.

Let me briefly outline what he did. An amateur trader who jumped into the stock market in his 20s managed to exponentially grow his assets in just a few years. His actions during the 2005 JCOM incident are especially famous. Due to a system failure at Mizuho Securities, stocks that should have been sold at 610k yen were suddenly available at 1 yen in large quantities. While other traders panicked, BNF calmly bought 7,100 shares at the low price. Later, when the price recovered, he took profits and made several tens of millions of yen in a single trade. This episode alone shows how well he could read the market trends.

However, his path wasn’t perfect. During a period when he heavily invested in U.S. stocks, the market unexpectedly crashed, resulting in losses exceeding $10 million. This is a crucial point. Even successful traders fail sometimes. But what matters most is how they recover. He returned to his trading principles, enforced strict discipline, and made a comeback.

What can cryptocurrency traders learn from BNF? First, controlling emotions is essential. Especially when the market is full of volatility, staying calm is key. Next, the importance of sticking to your own rules. Most traders who incur losses start by breaking their own rules. Lastly, having a mentor is invaluable. Listening to experienced advice can save you from paying high tuition fees for mistakes.

Looking at BNF’s current influence, his lessons are still very relevant. In fact, now that the markets have become more complex, returning to fundamental principles is more important than ever. Discipline, calmness, and consistency—if you have these three, you can survive in any market environment. Traders who manage their positions with these principles tend to succeed in the long run.
