In 20 years, a friend asked me, if you wake up now and find a billion Dogecoins, would you sell them? I said, I would sell half and see how it goes.

He said he didn't believe it. He thought that if it were him, and he originally didn't have it, now that you gave it to me, no matter the price, I would sell immediately because it's a free gain. He couldn't believe anyone could withstand such volatility without having seen money before.

Now, it seems like I am practicing that initial idea. Do people really not change?

But thinking carefully, he's right. If I haven't seen money or experienced big swings, I wouldn't be able to hold on.

Being able to hold is just because I'm used to positions of hundreds of thousands to 1 million dollars, and I can tolerate or endure fluctuations of a few thousand or tens of thousands of dollars.

I've always believed that the most important thing in investing is understanding yourself, just like when you go to Alipay and want to manage your finances. They ask you to do quizzes or fill out questionnaires to understand what investment style suits you. That's the most important part—there's human nature hidden in it.
