In a Facebook post , Sun, founder of the Tron cryptocurrency platform, said he and several of his guests had an "Amazing dinner w/ Warren Buffett finally!" It included a photo of Buffett and Sun posing along with four other guests.

Cryptocurrency entrepreneur Justin Sun finally got his $4.6 million charity auction dinner with Warren Buffett last month.

Justin Sun had a charity dinner with Warren Buffett along with Sun's guests.

Sun also posted photos of gifts he presented to Buffett including one bitcoin , "safely stored" in a Samsung Galaxy Fold. "Since I gifted him this #Bitcoin, $BTC has increased 16%! Hope it continues to moon!" Sun wrote.

Sun added, "Thx for your support & advice on how to take #TRON to the next level! Loved our talk on #Bitcoin , #Tesla & #TRON! Glad to support GLIDEsf as well! C U at # BRK2020 & our reunion meal in 2030!"

Buffett has been very vocal with his opinion that bitcoin is benefiting from an investment bubble and is not suitable for long-term investors. He does, however, see value in the underlying blockchain technology.

Along with the bitcoin, Sun also gave Buffett a bronze horse, "since we are both born in Year of the Horse, 1930/1990!" and a "traditional Chinese paper cutting of mouse in celebration of the Year of the Mouse 2020."

Sun posted a photo of the meal's receipt, saying "Most delicious meal ever! Thks Warren Buffett for taking us to Happy Hollow Club! $4.56 MIL for a $515.05 dinner was money well spent! The insights I received are priceless." The receipt is signed by Buffett and dated January 23.

CoinDesk reports Sun's guests included Litecoin creator Charlie Lee, eToro CEO Yoni Assia, Huobi CFO Chris Lee, and head of the Binance Charity Foundation, Helen Hai.

Sun's $4.5 million bid was the winner in the 2019 auction of a meal with Buffett.

A dinner had originally been scheduled for last July but was abruptly postponed when Sun said he was suffering from kidney stones. Around the same time there were stories in Chinese media that Sun was under investigation.

Sun later apologized for "over-marketing" the event ahead of time.
