What Happened?
The UK’s Financial Conduct Authority (FCA) has launched a civil lawsuit in London’s High Court against crypto exchange HTX, accusing the platform of illegally promoting crypto services to British consumers. The exchange, formerly branded as Huobi, is linked to Tron founder Justin Sun, who serves as an adviser to the company.
The FCA claims HTX operated in breach of the UK’s financial promotions regime, which mandates that crypto firms must receive authorization or have their advertisements approved before targeting local users.

FCA’s Legal Action: A Long Time Coming
This legal step comes after repeated warnings from the FCA over the past year. In October 2023, the agency added HTX to its unauthorized firms list, cautioning users that the platform could be offering services without oversight.
Now, the FCA has filed a civil case against HTX and four unnamed individuals involved in its operations and marketing activities. A spokesperson from the FCA said the action aims “to protect consumers and uphold the integrity of UK financial markets.”
While Justin Sun is widely known to be associated with HTX, the FCA did not confirm whether he is personally named in the lawsuit. His role has drawn attention due to his high profile in the crypto space and ongoing legal challenges in the United States.
UK’s Stricter Crypto Oversight Takes Shape
The FCA’s case against HTX is one of the first major tests of the UK’s updated crypto advertising rules, which came into effect on October 8, 2023. These new regulations require any crypto company promoting services to UK customers to meet strict compliance standards, regardless of where the business is based.
The UK government has been preparing broader policies to regulate crypto markets, including:
- Plans to appoint a digital markets champion.
- Opening access to regulated Bitcoin and Ethereum exchange-traded products.
- Proposing frameworks to bring more crypto firms under UK oversight in the coming year.
This growing regulatory push is aimed at cleaning up misleading advertising and holding international crypto companies accountable when they target British consumers.
Impact on HTX and Justin Sun
HTX has yet to respond to the lawsuit. The exchange has been in the spotlight since Tron founder Justin Sun acquired it in 2022. Sun, who now calls himself the Prime Minister of Liberland, has also faced charges from the U.S. Securities and Exchange Commission for alleged unregistered securities sales and wash trading of TRX and BTT tokens.
This UK lawsuit adds to the pile of legal troubles surrounding Sun and his ventures. Market watchers are closely observing how HTX will react and whether any interim court measures, such as injunctions or fines, will be imposed.
The case could set a precedent for how foreign crypto exchanges handle promotions in the UK. According to the FCA, more enforcement cases are expected, as the agency tightens its grip on crypto advertising.
SQ Magazine’s Takeaway
I’ve got to say, this case is a big wake-up call for global crypto firms trying to tap into the UK market without playing by the rules. The FCA isn’t just sending warnings anymore, it’s going to court. And that’s a serious escalation. Justin Sun being connected to yet another legal drama just adds fuel to the fire. If HTX and others don’t tighten up, they’ll find themselves in hot water fast. This is about consumer protection and credibility, and regulators worldwide are clearly done with the wild west approach in crypto.
