Seattle-based cryptocurrency exchange Bittrex, Inc. has announced it will wind down its U.S. operations from April 30 due to continued regulatory uncertainty in the region. The exchange stated that regulatory requirements are often unclear and enforced without appropriate discussion or input, resulting in an uneven competitive landscape, which has made operating in the U.S. unfeasible. Trading will be allowed on the platform until April 14, and all customer funds are safe and available. Bittrex will focus on the growth of Bittrex Global, its Liechtenstein-based trading arm serving investors outside the U.S. (forkast)
