The US Commodity Futures Trading Commission has filed a lawsuit against crypto trader Avraham Eisenberg for allegedly manipulating swaps contract prices as part of a $114 million scam. Eisenberg engaged in “a manipulative and deceptive scheme” in October to inflate the price of swaps offered by decentralised digital-asset exchange Mango Markets, resulting in the misappropriation of funds, according to a complaint filed by the regulator on Monday. Eisenberg was arrested in Puerto Rico last month and charged with fraud by prosecutors in New York for the exploit. Eisenberg is accused of manipulating the price of perpetual swaps by 1,300% in a matter of minutes using two Mango Markets accounts he controlled.
