Kim Kardashian has agreed to settle charges of 1.26 million dollars (£1.1 million) in penalties for promoting a cryptocurrency on social media without disclosing the payment she received for it.

The SEC revealed the reality TV star has agreed to cooperate with its ongoing investigation.

The agency said Kardashian failed to disclose that she was paid 250,000 dollars (£222,000) to publish a post on her Instagram account about EMAX tokens, a crypto asset security being offered by EthereumMax.

Kardashian’s post contained a link to the EthereumMax website, which provided instructions for potential investors to purchase EMAX tokens.

Gurbir Grewal, director of the SEC’s division of enforcement, said in a prepared statement: “The federal securities laws are clear that any celebrity or other individual who promotes a crypto asset security must disclose the nature, source, and amount of compensation they received in exchange for the promotion.”

Cryptocurrency has attracted increasing attention from US congress. A bipartisan proposal last month would hand the regulatory authority over Bitcoin and Ether, two popular cryptocurrencies, to the Commodities Futures Trading Commission after wild swings in crypto valuations, dozens of scams and hundreds of billions of dollars gained and lost.

Kardashian is not the first celebrity to attract the attention of regulators for their involvement in cryptocurrency.

In 2018, the agency settled charges against professional boxer Floyd Mayweather Jr and music producer DJ Khaled for failing to disclose payments they received for promoting investments in digital currency.

This year, crypto investors have seen prices plunge and companies crater with fortunes and jobs disappearing overnight, and some firms have been accused by federal regulators of running an illegal securities exchange.
