Founder of the Tron blockchain Justin Sun has published a tweet to say he believes that the founder of the Berkshire Hathaway investment fund and one of the world’s wealthiest men, Warren Buffett, holds one Bitcoin. He stated this despite the well-known fact that Buffett is a Bitcoin critic, who referred to BTC as “rat poison squared” six years ago, thus warning investors not to get involved with the world’s leading digital currency. Justin Sun, the creator of Tron blockchain and owner of Poloniex and Huobi exchanges, seems to believe that the Oracle of Omaha (Buffett’s nickname in financial circles) continues to hold the Bitcoin that Sun presented to him during the charity dinner that took place in 2020.
