Chicago-based trading giant Jump is returning its U.S. cryptocurrency business to full operational status after scaling back operations over the past two years due to regulatory scrutiny and uncertainty. According to people familiar with the matter, while Jump has been maintaining digital asset trading and market-making activities in other parts of the world, the growth of crypto trading volume in the United States is currently accelerating. Jump is planning to hire a group of crypto engineers and will start filling US policy and government liaison positions in due course. In the context of the deregulation of Donald Trump's administration, Jump believes that now is the right time to return the US business to full operation.
