Mr. Duan said, 'Do the right thing.'

What is the right thing?

At my age, I actually just want to make simple money like I used to when I only received a fixed salary and didn't understand cryptocurrency, and play with cryptocurrency.

At first, I couldn't figure it out, but I kept thinking about it, and eventually, I understood and could do it.

He said the right thing is to not do the wrong thing.

As soon as you discover something wrong, stop immediately. No matter how costly the mistake is, stopping the loss immediately is still a profit.

Even now, I continuously use my own and those around me to concretize this concept.
