Warren Buffett once called bitcoin “probably rat poison squared.” He’ll now have to dine with one of the cryptocurrency’s biggest fans. Sun’s winning bid, which the 28-year-old announced on Twitter, was confirmed by the Glide Foundation, whose five-day online auction on eBay ended on Friday night. Sun can invite up to seven people to dine with Buffett at the Smith & Wollensky steakhouse in midtown Manhattan.
