On April 18, the US SEC filed an amended complaint in its case against Justin Sun and other defendants, contending that Sun's reported visits to the US justify the jurisdiction needed for legal action.

The regulator claimed that Sun extensively traveled to the US while he and various companies conducted unregistered offers and sales of BTT and TRX tokens. According to the SEC, Sun spent more than 380 days in the US between 2017 and 2019, making business trips to major cities like New York City, Boston, Massachusetts, and San Francisco on behalf of the Tron Foundation and the BitTorrent Foundation, both named as defendants in the case.

The SEC aims to leverage these trips to establish jurisdiction over Sun and the companies for regulatory and legal action in the US.

Regarding wash trading, the SEC alleged that Sun and the companies participated in a wash trading scheme on the now-defunct crypto exchange Bittrex. Although the original complaint outlined similar wash trading activities, it only referred to the exchange as an unnamed "trading platform." The amended complaint explicitly mentions Bittrex, emphasizing its US-based status alongside other claims to personal jurisdiction over Sun and the other defendants.

Furthermore, the amended complaint alleges that Sun personally communicated with and provided documents to Bittrex circa 2018 to list the TRX crypto. These documents link Sun to the other companies, with Sun personally signing some of them.

The latest allegations address concerns raised by Sun in his March request to dismiss the SEC case due to a lack of personal jurisdiction. Defense lawyers argued that Sun, as a foreign national, is not "at home" in the US, advancing similar arguments for the companies. The request for dismissal also pointed out alleged improper distributions on Bittrex but noted the absence of allegations that any US resident purchased or attempted to purchase TRX on the platform in question.

The SEC initially sued Sun and the other defendants in March 2023, primarily basing personal jurisdiction claims on sales targeting investors in the Southern District of New York and allegations of celebrity promoters contacting individuals in the US via social media.

In a separate lawsuit, the SEC sued Bittrex in April 2023 and settled the case in August 2023. The company ceased global operations in late 2023.
