A colleague of mine is particularly frugal in everyday life.

He only orders the cheapest takeout and even shares rides.
Everyone thinks he's good at managing his money.
Last year, he started trading cryptocurrencies.
At first, he made some money.
Then he invested more and more.
Once, during a market crash, he lost 200,000 yuan overnight.
The next day, he still came to work as usual, and for lunch, he ordered the cheapest box meal.
I couldn't help but ask him:
“Aren't you reluctant to spend money?”
He replied:
“That's different.”
I asked how.
He said:
“Money in daily life is my own.”
“Money in the market is a chance to grow.”
At that moment, I realized that
many people are not necessarily frugal,
they're just more sensitive to “money that is certain to lose.”
