Chinese cryptocurrency entrepreneur Justin Sun Yuchen has finally sat down for a meal with Berkshire Hathaway chairman and legendary investor Warren Buffett after postponing it last year due to a kidney stones issue. Sun bid a record US$4.57 million for the opportunity to have lunch with Buffett at a charity auction last June but postponed it first citing health issues then apologising to the public for overhyping the plan to dine with one of the world’s richest people. Sun thanked Buffett for his dinner, wisdom and vision. “US$4.56 million for a US$515.05 dinner was money well spent! The insights I received are priceless,” Sun said on Twitter on Thursday. The 20th-anniversary charity lunch hosted by Warren Buffett was originally scheduled for July 25 last year. Sun earlier said on Twitter that he intended to invite blockchain industry leaders to join him and hope “this benefits everyone”. Sun and four other cryptocurrency advocates finally met Buffett on January 23 at the Happy Hollow Club in Omaha, Nebraska. Sun’s guests were Charlie Lee, the creator of peer-to-peer internet currency payment service provider Litecoin; Chris Lee, the chief financial officer, board secretary and vice-president of international business development at Chinese cryptocurrency exchange Huobi; Yoni Assia, founder and chief executive of social trading and multi-asset brokerage company eToro and Helen Hai, head of the Binance Charity Foundation. Cryptocurrency celeb ran a hook-up app before his US$4.6m Buffett lunch bid Sun also brought Buffett several gifts, including a Bronze Horse, a traditional Chinese paper cutting of a mouse and a Galaxy Fold phone stored with one bitcoin. Sun, founder of cryptocurrency platform Tron and chief executive of software company BitTorrent, is a controversial figure in China. Shortly after he came under the spotlight because of the Buffett lunch, Chinese media Caixin reported that Sun was under investigation by local authorities and was not allowed to leave China, though Sun subsequently posted a video on his Twitter account, saying he was in San Francisco. The entrepreneur was allegedly involved in illegal fundraising via the Tron project, which operated illegal gambling services accessible to Chinese residents, according to a report by The 21st Century Business Herald. The report also noted that Sun’s early start-up Peiwo, a social app which allows strangers to chat with each other, had been accused of being a vulgar and pornographic business. Sun has denied the illegal fundraising and money laundering accusations, but admitted that some content on his social app Peiwo had “negative energy”.
