Five years ago, Sun Yuchen, a post-90s from China, won a staggering 30 million yuan bid for a lunch with Buffett, shocking the investment community. At that time, most of his peers were still confused about their career direction, while he became the focus of public opinion due to his influence in the virtual currency field.

Buffett's charity lunch had been an annual event in the investment world for 21 years, serving both as a fundraiser for charity and a valuable learning opportunity for investors. Among the Chinese investors participating in the bidding, three were controversial for allegedly using Buffett's fame to commit fraud, and Sun Yuchen's lunch appointment further escalated the incident, leading to the quiet end of this traditional event in 2022.

In the cryptocurrency field, Sun Yuchen is highly controversial. He rose to prominence with unique marketing and bold strategies, and the news of winning the lunch in 2021 was shocking—given that Buffett adheres to the value investment philosophy and has a cautious attitude towards speculative assets like virtual currency.

Sun Yuchen regarded the lunch as a marketing opportunity, initially canceling the meeting citing kidney stones, then repeatedly postponing it. Each change sparked heated discussion and drove the price of the TRON coin he founded to soar. This months-long “hype drama” significantly increased his and TRON's visibility. Ultimately, the lunch was held at a rural hamburger shop in the United States, in a simple environment. He treated Buffett to burgers and presented a phone pre-installed with the TRON app, claiming, “Buffett has also become a holder of virtual currency,” which was a bold challenge to traditional investment concepts.

After the lunch, Buffett publicly expressed negative views on virtual currency several times, emphasizing its lack of intrinsic value and categorizing it as a high-risk speculative product. The following year, he announced the permanent cancellation of the charity lunch, which was believed to be related to the negative impact of the Sun Yuchen incident.

This incident offers many insights: integrity is crucial in business activities, and violating ethics will ultimately have consequences; marketing should be reasonable and legal, respecting the reputation of others; investors need to remain rational when facing emerging fields like cryptocurrency.
