Ethereum and idealism (3)

In the world of investing and finance, idealists don't survive. For example: There is a classic saying in teacher Li Xiaolai’s classic recording:

"I cao, NM talks about value investing all day long, so damn, I'll just give you an example. I scold Chinese medicine every day, and Chinese medicine is SB, but I really bought the stocks of listed Chinese medicine companies. The reason why is very simple. I know the trust of SB, and there are many SBs. Then I know that if I don’t buy it, others will buy it. Why don’t I make money? It’s business. In the end, there is no world more successful than the world of finance. of."
