Justin Sun, the founder of the TRON Foundation who won an annual auction to have lunch with billionaire investor Warren Buffett, has invited the founder and CEO of eToro, Yoni Assia, to the event. Sun has so far invited four individuals to go with him.

Assia responded to Sun’s invitation via the popular microblogging platform Twitter, accepting it.

Sun has earlier this month invite3d the head of the Binance Charity Fund, Helen Hai, to go as well. Hai agreed to go, stating the lunch was a great opportunity to discuss cryptocurrency and philanthropy. Jeremy Allaire, the CEO of cryptocurrency payments firm Circle, which acquired the cryptocurrency exchange Poloniex last year, was also invited.

The first to be invited to go with Justin Sun, who paid a record $4.56 million to have lunch with Buffett, was Litecoin founder Charlie Lee. Three more invitations to the event are expected. The lunch will take place on July 25 at Quince, a popular restaurant in San Francisco with three Michelin stars.

Buffett has been auctioning off a chance to have lunch with him since 2000, as a way to support one of his favorite charities, the Glide Foundation, which provides meals for San Francisco’s homeless, supports domestic violence victims, and more. The event has already raised over $30 million for the charity, according to Forbes.

Sun winning the auction this year is significant, as various prominent personalities from the cryptocurrency space will attend the lunch with him. Buffett is a well-known bitcoin bull, who earlier this year claimed the flagship cryptocurrency is a “gambling device.”

Last year, during Berkshire Hathaway’s annual shareholder meeting, Buffett slammed bitcoin by stating it is “probably rat poison squared.” Charlie Munger, Berkshire’s vice chairman, took a harsher stance and compared the cryptocurrency to “turds” and “dementia.”

Who else is going to join Sun in his lunch with the “Oracle of Omaha” remains to be seen, although some have made it clear they’re available. Anthony Pompliano, co-founder and partner at Morgan Creek Digital, expressed interest, for example
