In recent years, the legendary trading method that has once again come under the spotlight in the cryptocurrency trading world is BNF, short for Takashi Kotegawa’s story. Why is his name resurfacing now? It’s probably because more and more traders are starting to realize that the principles he demonstrated still hold true even in crypto markets with high volatility.

Do you know about the Jaycom incident that took place in Japan’s stock market in 2005? A trader at Mizuho Securities mistakenly sold 610,000 shares for 1 yen. At that moment, most traders would either panic or miss the opportunity. But BNF was different. He calmly bought 7,100 shares at a low price, then took profits in stages when the price rose afterward. In the end, he walked away with a profit of $17 million. He was only in his twenties at the time.

With just this one trade, his name was etched into the market. But his true greatness isn’t there. From initial capital of $13,600, he grew his assets to $17 million in 2 years, and by 2008 he had increased them to $153 million. Along the way, he also experienced failures again and again. He even suffered losses of more than $10 million from overinvesting in U.S. stocks. Yet he learned from those experiences and came to fully understand the importance of strictly following rules.

The reason BNF is still referenced today is not just the amount of money he made, but his trading philosophy. When the market is in frenzy, that’s when you must not be swayed by emotions and instead follow the system. This is true for both crypto markets and stock markets. Emotional decision-making ruins 90% of traders. BNF treated trading like a game and was able to keep a psychological distance from gains and losses. That’s why he stayed calm even amid major market swings.

Another interesting point is that he talks about the importance of mentors. Cryptocurrency is high-risk. With the right guidance, you can avoid costly mistakes. The phrase that “the network is net worth” still resonates even in today’s crypto community.

Looking at BNF’s current influence, it’s clear that nearly 20 years after his era, market participants are still trying to return to his principles: discipline, calmness, and rule compliance. It’s not flashy, but it really works. If you want to raise your level in crypto trading, mastering these basics may be the quickest path.
