Justin Sun: The Teflon Troll of Crypto

On 29 November 2024, in a ballroom at the Peninsula hotel in Hong Kong, Justin Sun peeled a banana off a wall and ate it. Nine days earlier he had paid $6.2 million at Sotheby's in New York for "Comedian", the Maurizio Cattelan artwork that consists of one banana and a strip of duct tape. He told reporters it tasted better than other bananas.

That is roughly how Sun runs his public life. He is the founder of Tron, a blockchain network worth billions, and one of the most litigated people in crypto. In March 2023 the US Securities and Exchange Commission (SEC) accused him of fraud and market manipulation. Three years later he walked away without paying a cent himself. By then he was suing the Trump family's crypto company.

From Peking University to Tron

Sun was born in 1990 in Xining, in western China, studied history at Peking University and took a master's degree at the University of Pennsylvania, where he bought his first bitcoin. He worked as the China representative of Ripple, a payments company, before founding Tron in 2017.

Tron is a blockchain: a shared public ledger that records who owns what, kept by a network of computers instead of a single company. Its coin is TRX. Sun raised about $70 million for it in September 2017 through an initial coin offering (ICO), a crowdfunding sale of new tokens that works like a share flotation with no regulator, no prospectus and no obligation to deliver anything. The sale closed days before China banned ICOs.

He bought his way to attention. In 2018 Tron acquired BitTorrent, the file-sharing company, for a reported $140 million, and later launched a BTT token on top of it. In 2019 he won Warren Buffett's annual charity lunch auction with a bid of about $4.57 million, cancelled it, and finally ate with Buffett in Omaha on 23 January 2020. He bought the Poloniex exchange in 2019 and took control of Huobi, now HTX, in 2022. An exchange is crypto's version of a broker: where customers buy and sell coins. In December 2021 Grenada, a Caribbean island nation of about 125,000 people, made him its ambassador to the World Trade Organization in Geneva. He held the post until March 2023, when the government that appointed him lost power.

What the SEC said he did

On 22 March 2023 the SEC sued Sun, the Tron Foundation, the BitTorrent Foundation and Rainberry, BitTorrent's owner, in federal court in Manhattan. It made three main accusations.

The first was that TRX and BTT were securities, investments whose value depends on the work of the people behind them, and that Sun had sold them in the United States without registering them, as a company would have to before an IPO.

The second was wash trading. A wash trade is buying from yourself: one hand sells, the other buys, and the market sees activity that does not exist. It is the shopkeeper hiring people to queue outside his own door. According to the SEC, from April 2018 to February 2019 Sun's staff made more than 600,000 wash trades of TRX between two accounts he controlled, between 4.5 million and 7.4 million TRX a day, to make the coin look heavily traded. Meanwhile, the agency said, he sold TRX into that market and made about $31 million.

The third was paid promotion. The SEC said Sun hired celebrities to promote TRX and BTT on social media without telling their followers they were being paid. It charged eight of them: the actress Lindsay Lohan, the YouTuber and boxer Jake Paul, the rappers Soulja Boy, Lil Yachty and Akon, the singers Ne-Yo and Austin Mahone, and the adult film actress Kendra Lust. Six settled straight away for a combined total of more than $400,000, without admitting or denying anything. Mahone settled later that year. Sun denied the charges. "This case demonstrates again the high risk investors face," said Gary Gensler, then chair of the SEC.

How it went away

Then Washington changed. In November 2024, weeks after Donald Trump won the presidential election, Sun announced he had invested $30 million in World Liberty Financial (WLF), the crypto venture launched by Trump and his sons, and became an adviser. According to his later lawsuit, he bought $45 million of WLFI tokens in all. In February 2025, with a new, crypto-friendly leadership at the agency, the SEC and Sun asked the court to pause the case while they discussed a resolution. In May 2025 he was among the top holders of the $TRUMP memecoin invited to dinner with the president at his golf club in Virginia. In August 2025 he finally flew to the edge of space on Blue Origin's New Shepard rocket, four years after bidding $28 million for a seat.

In March 2026 the deal arrived. Rainberry agreed to pay a $10 million civil penalty without admitting or denying the allegations. The SEC dropped every claim against Sun, the Tron Foundation and the BitTorrent Foundation with prejudice, which means it can never bring them again. Soulja Boy's charges were dropped too. Sun paid nothing and was barred from nothing. None of the accusations was tested in court.

The fight with World Liberty

Sun's alliance with the Trump family did not last. In early September 2025, days after WLF's token, WLFI, began trading, the project blacklisted a wallet linked to him, freezing hundreds of millions of tokens. Blockchain analysts had just watched that wallet move 50 million WLFI, worth about $9 million, toward HTX. Sun said the transfers were small deposit tests and that "no buying or selling was involved." WLF said it acts when alerted to "malicious or high-risk activity."

On 21 April 2026 Sun sued WLF in federal court in California. He says the company secretly built a blacklisting tool into its token, used it to stop him selling about 4 billion WLFI, worth roughly $320 million by Reuters' estimate, and froze him after he resisted pressure to commit $200 million to a separate WLF stablecoin and an equity stake. WLF's chief executive, Zach Witkoff, called the claims "entirely meritless". Eric Trump wrote that the only thing more ridiculous than the lawsuit was spending $6 million on a banana. In May WLF countersued in Florida, accusing Sun of defamation, of short selling WLFI and of buying tokens through straw buyers. Sun denies it. On 20 August 2026 Judge James Donato refused WLF's bid to push Sun's personal claims into private arbitration. Neither case has reached a verdict.

His other businesses are not doing quietly either. Poloniex lost about $120 million to hackers in November 2023. In May 2026 Britain sanctioned HTX, accusing it of serving A7, a Kremlin-linked payments network, and Garantex, a sanctioned Russian exchange. It was the first crypto exchange designated under Britain's Russia sanctions. HTX said it is committed to complying with the law. Sun himself was not named. He is, according to Forbes, worth about $8.5 billion.
