The New York Attorney General's Office filed another letter to Judge Joel Cohen regarding Bitfinex and Tether claiming any exchange would have the requested information "at its fingertips." The exchange's parent company iFinex has sought to refrain from handing over materials and actively participating in the NYAG's fraud investigation into Bitfinex. Bitfinex's counsel also filed a letter yesterday saying the exchange had spent over $500,000 in responding to the NYAG's document demands, and that finding documents for the investigation was a costly procedure.
