The most frightening thing is not having never made a lot of money.
It is that after making a lot of money, you start to believe you can’t lose.
This is the real experience of Japanese investor “りゅん”.
At his peak, his assets once reached:
1 billion yen.
For most people, by this point, retirement is probably already under consideration.
But he didn’t stop.
The more he earned, the larger his positions became.
The larger his positions became, the higher the leverage.
Nintendo, Sanrio, Kioxia...
He began constantly using margin trading and betting with full leverage.
At the most intense moments, with 1 billion yen in capital,
a few minutes of fluctuation meant several million yen.
The thrill of making money also made him numb to risk.
Then the market began to strike back.
1 billion yen → 200 million yen → under 100 million yen...
He later explained it himself:
He lost about 200 million yen on Kioxia,
and another about 700 million yen on highly leveraged trades such as Nintendo and Sanrio.
Until August 2026, he posted one sentence:
“Who would have thought my assets would fall from 1 billion to 9 million.
-99% for the year.”
From 1 billion to 9 million.
It was not that he couldn’t make money.
It was that he could make money, but had not learned how to keep it.
This may be the cruelest lesson in the investment market:
Turning 1 million into 10 million takes skill.
Turning 10 million into 100 million takes skill plus luck.
But when you truly have 1 billion, the most important thing is no longer how to double it again—
It is how not to give it back to the market.
What many traders end up losing in the end
is not their first principal.
It is the version of themselves that, after making money, becomes more and more convinced they “won’t lose.”
Staying alive is more important than making money fast.
