Who was defrauded? “Journalists” and “journalism” websites want clickbait.
The whole purpose is to give the “journalist” just enough plausible deniability to write a clickbait headline, which benefits CNBC/BBC and the person selling within their family.
As far as I know, misleading “news” is not illegal.
No-one needs to be defrauded to make out an offence of Fraud in the UK.
"Fraud by false representation" happens when someone dishonestly makes a false representation with the intent to make a gain for themselves or another. Making up a news story to flip NFTs would almost certainly amount to a crime of fraud by false representation.
