Justin Sun (Chinese: 孙宇晨; pinyin: Sūn Yǔchén; born July 30, 1990) is a Chinese-born cryptocurrency entrepreneur and business executive.

[10] In October 2021, Sun participated in a $65 million funding round in Hong Kong-based Animoca, a maker of crypto and blockchain video games such as The Sandbox.

[21] In October 2024, Sun was elected as a "Speaker of Congress" and appointed as "Prime Minister" of Liberland, a micronation (self-proclaimed country) that claims to own (but does not control) a small region on the Danube river floodplain border between Serbia and Croatia.

[22] Sun founded Peiwo, an app aspiring to become China's Snapchat that matches and connects users by analyzing 10-second voice samples as well interests.

Peiwo has introduced a host of channels for users to make like-minded friends, with online games, talent shows and live streaming.

[11] In 2020, a civil lawsuit was filed against Sun by former TRON employees Lucasz Juraszek and Richard Hall, with allegations "ranging from fraud to harassment to whistleblower retaliation".

[11] In March 2023, Sun was sued by the U.S. Securities and Exchange Commission for selling unregistered securities related to the sale and promotion of Tron (TRX) and BitTorrent (BTT) tokens, alleging that Sun and his companies had engaged in fraudulent activities such as wash trading in the secondary market for TRX in order to raise its price.

[3][24][25] Eight celebrities, including Akon, Ne-Yo, Austin Mahone, Soulja Boy, Lindsay Lohan, Jake Paul and Lil Yachty were charged with promoting these cryptocurrencies without disclosing that they were sponsored.

[26][27][3] Prior reporting by The Verge also alleged that TRON, at the direction of Sun, had engaged in market manipulation by buying/selling TRX tokens based on non-public internal information.

[10] Sun placed the winning $4.6 million bid to have a private meal with Berkshire Hathaway CEO Warren Buffett in June 2019,[28][29] before canceling it to widespread surprise.

[32][33] Sun was joined by other cryptocurrency executives, including leaders of Litecoin, eToro, Huobi, and Binance Charity Foundation.

[36] In December 2021, Sun announced that he had previously bid $28 million to be the first paying passenger on Blue Origin's first crewed mission into space on the New Shepard.
