According to the BBC, the Portuguese international is being sued for a sum of one billion dollars (around 915 million euros).
The partnership between Ronaldo and Binance, it should be noted, was signed in 2022. At the time, the CR7 collection of 'non-fungible tokens' (NFTs) was launched, with the cheapest costing 77 dollars - in November 2022. A year later it was worth about a dollar.
According to the lawsuit now published, Ronaldo's presence in Binance advertising led the plaintiff to lose money in this type of investment.
The lawsuit, cited by Brazilian website Exame, alleges that Cristiano Ronaldo "promoted, assisted and/or actively participated in the offering and sale of unregistered securities in coordination with Binance."
It is worth remembering that the CEO of Binance, Changpeng Zhao, agreed to plead guilty to money laundering crimes and pay a fine of 50 million dollars, in a hearing that took place this week in a court in Seattle, also in the USA.
In June, the United States Securities and Exchange Commission (SEC) sued Binance, the largest cryptocurrency platform in the world, for violating regulations in force in the country with its operations.
Contacted by the BBC, both Ronaldo and Binance did not react to the process.
