NEW YORK: Fallen cryptocurrency wunderkind Sam Bankman-Fried has appealed his federal conviction and 25-year jail sentence in a sweeping fraud case, according to a legal filing made public April 11.

News of the appeal comes two weeks after US District Court Judge Lewis Kaplan set the prison term and ordered Bankman-Fried, known as “SBF”, to pay US$11bil (RM52.44bil) in forfeiture.
