An independent crypto-gaming developer sued an established trading firm in a federal district court in Illinois that facilitated an initial exchange offering on behalf of the company, but instead allegedly carried out a "pump and dump" scheme that netted an eight-figure return.

Deanna Lee Oswald and Benjamin H. Brodsky, of counsel and a shareholder, respectively at Brodsky Fotiu-Wojtowicz in Miami, represent the plaintiff, FractureLabs OÜ, an Estonia-based company, that sued the defendant, Jump Trading LLC, for fraud and deceit, civil conspiracy, breach of contract and breach of fiduciary duty. Oswald and Brodsky did not respond to a request for comment; neither did Jump.
