During closing arguments Monday in the wire fraud and money laundering trial of a former employee of the NFT exchange OpenSea, attorneys for the prosecution and defense each acknowledged that the jury’s verdict will rest on whether or not it thinks the defendant knew what he was doing was wrong.

Greenberg Traurig shareholder Daniel Filor, who represents former OpenSea product manager Nathaniel Chastain, said his client does not dispute that he “bought low [and] sold higher” as he purchased and then sold the NFTs he had chosen to feature on OpenSea’s website homepage.
