Tron CEO Justin Sun could not attend his ballyhooed lunch on Thursday with finance titan Warren Buffett due to kidney stones, he said. It did not prevent him from briefly interfering with influencers on a Tron-organized party on Thursday night in San Francisco.
The appearance comes just a day after Sun wrote an apology to the public, media and regulators of "over-marketing" the Buffett luncheon, he did not specify which regulators he referred to, but the letter has so far only been posted in simplified Chinese.  "In the future, because of my illness, I will take some rest," he wrote in Weibo post. "All efforts will return to blockchain-technological development from marketing and hyping."

Despite the postponement of the main event – which Sun filed $ 4.6 million donation to charity – plans for the Sun's confab party with Buffett as planned.
Ten YouTubers bl e flown to San Francisco for Tron Influencer Day to celebrate the anniversary of Tron's acquisition of BitTorrent, the saved file-sharing platform founded in 2004.
Meanwhile, BitTorrent founder and current Chia CEO Bram Cohen seemed strongly dissatisfied. "Someone who knows about Justin Sun is having trouble with money?" Cohen tweeted Thursday afternoon. "He doesn't let the last payment for BitTorrent come out of escrow." (Speaking of decrypting, Sun completely denied the accusation and said, "It has nothing to do with me.")
Sun's appearance turned out to be a strange bookend to a week-long tale of the polarizing entrepreneur. The reports appeared on Tuesday that he was under border control and was prevented from leaving China. These reports were refuted later that day when Sun sent a video of herself from a San Francisco high-rise building.
A new date for deferred lunch has not yet been announced.
