A former Jane Street trader brought in by Sam Bankman-Fried to work on FTX's charity projects is fighting a legal battle for the remainder of his 2022 bonus. Ross Rheingans-Yu's lawyers claim the exchange only paid him $375,000 of his $650,000 bonus and owes him another $275,000. Rheingans-Yu said he was unaware of the cryptocurrency scam and denies the allegations made by new FTX management in July . He is also asking for another $650,000 in charitable donations.
