Odaily News Chicago-based trading giant Jump is returning its U.S. cryptocurrency business to full strength after scaling back its U.S. cryptocurrency business in the past few years due to regulatory scrutiny and uncertainty. While Jump has maintained its digital asset trading and market-making activities in other parts of the world, cryptocurrency trading volumes in the United States are now accelerating, according to a person familiar with the matter. In addition, another person familiar with the matter said Jump is looking to hire a group of crypto engineers and plans to start filling the position of U.S. policy and government liaison in due course.
