Centra Tech’s promoter, an initial coin offering scam, plead guilty before an American Court. Robert Farkas, who is 33, who promoted Central Tech, admitted before the US court that he defrauded investors for $25 million. Central Tech became quite famous after being endorsed by celebrities like boxer Floyd Mayweather and DJ Khaled. Floyd Mayweather even called himself Crypto Mayweather at some point, as far as I remember, which was a play on his other nickname – Money Mayweather. Both of them were slapped with a pretty large fine for their involvement with and endorsement of a scam company that ripped people off with millions of US dollars.
SourceIt's very annoying when celebrities promote things blindly without bothering to look into the product they're promoting because they're too blinded by the payout.
