Many of Duan Yongping's investment philosophies are similar to Buffett's, such as not being interested in assets without cash flow (gold, Bitcoin). That's one. Secondly, Buffett, at his age, does have a somewhat outdated knowledge structure. Being able to buy Apple at 86 and then Google this year (at 95) is already a big change. There's only one week left until his retirement at the end of the year. 11 years ago, Buffett said Bitcoin doesn't meet the definition of currency. Was he wrong? Not really. Bitcoin is a type of digital commodity.
