Chinese blockchain and cryptocurrency entrepreneur Justin Sun has postponed his lunch with investing tycoon Warren Buffet due to kidney stones condition that is still under evaluation by medical experts.

Tron's young CEO, who is now additionally the CEO of BitTorrent, had bid an astonishing $4.5 million US dollars in order to meet with Buffet and discuss cryptocurrencies' future.

The bid was for a charity auction organized by San Francisco-based Glide Foundation, and Justin Sun had the opportunity to invite up to seven people at the lunch table.

Cryptocurrency officers and experts from all over the world were filing the list for some time now, and it appeared that the Litecoin Chief Charlie Lee, Jeremy Allaire, CEO of Circle, Huobi Global Chief Livio Wang, eToro CEO, Yoni Assia, and head of Binance Charity Foundation, Helen Hai, would all be attending the charity lunch with Warren Buffet.

“I was in the hospital due to kidney stones and had to cancel the lunch with Mr. Buffett … The donation to the Glide Foundation has been completed and is still valid,” said Justin Sun, in a post on Weibo, the Chinese equivalent of Twitter, on Tuesday morning.

The official account of TRON Foundation on Twitter also announced that lunch attendants had “agreed to reschedule at a later date”. In addition, the account has still Warren Buffet's lunch as a graphic cover.

Despite the situation, many doubts were raised on Weibo, questioning whether or not it is a new marketing strategy orchestrated by Sun himself, who has a large pre-history on 'behind the scenes' marketing.

"Sun has successfully created big news - and also the first man who breaks an appointment with Buffett," a netizen named Tusdt said on Weibo.

There were too many individuals, as well as media outlets who attacked Sun, saying that he was involved in money laundering, illegal fundraising activities.

While TRON's front face denied all accusations saying that TRON, has compiled with local Chinese laws and regulations, we know that he's kind of a 'student' of Charlie Lee.

For those who don't remember, you can search for the infamous Bitcoin Cash listing on Coinbase, where Charlie Lee, among other cryptocurrency heads, literally sold his LTC in order to invest in BCH prior to its surprise listing on Coinbase, under an insider-trading fashion.

BCH might have reached $3,5k per piece in a matter of days, but it appears TRON is not as lucky and organized as Charlie Lee was back in the day.

As a matter of fact, moments prior to the official Twitter announcement, price started to collapse at around 02:30 UTC this morning, while it ended up falling by 14.01% according to our cryptocurrency tracker at CoinCodex.com.

The charity lunch might have cost a lot in terms of funds for Justin Sun, but it seems that he's got a much more serious combination of issues to solve at the moment. On one hand his medical condition, on the other the attacks of so many people that might spike a more sophisticated investigation into Tron's crypto activities.

The 29-year-old TRON executive even sent an invitation to US President Donald Trump on Twitter after Trump said on July 12 that he was “not a fan of bitcoin and other cryptocurrencies” and “unregulated crypto-assets can facilitate unlawful behavior, including drug trafficking and other illegal activity.”

According to media reports, Sun convinced Buffett to move the charity lunch from New York to Silicon Valley, where he supposedly wanted to clear up some "misunderstandings" Buffet has on Distributed Ledger Technologies. Bold? Certainly, but let's assume that's how a young entrepreneur who's already passed the billion-dollar threshold moves nowadays.
