According to PANews, Berkshire Hathaway, a company under Warren Buffet, has seen its stock price fall nearly 99% against Bitcoin since 2015, dropping from about 1,000 Bitcoins to 9.15 Bitcoins. On June 3, Berkshire Hathaway's stock, BRK.A, experienced a brief and sharp decline due to a technical glitch at the New York Stock Exchange (NYSE). This incident drew the market's attention to the poor performance of Berkshire Hathaway's stock against Bitcoin.

Interestingly, Bitcoin's performance against BRK.A and its major stock holdings contrasts sharply with Buffet's critical view of Bitcoin, which he once described as 'rat poison'. According to the results of the Nakamoto Investment Portfolio Simulator, even if only 1% of Bitcoin is included in Berkshire Hathaway's existing investment portfolio, the return rate could be increased from 214% to 240% within a five-year adjusted time frame. Meanwhile, if 5% to 10% of the portfolio was allocated to Bitcoin during the same period, Buffet could potentially achieve a return rate of 328% to 410%.
