Cryptocurrency exchange Bittrex filed for bankruptcy in the U.S. state of Delaware on Monday. Bittrex Global business will not be affected by this, and Bittrex will continue to provide services to customers outside the United States. Bittrex has more than 100,000 creditors with estimated liabilities and assets of between $500 million and $1 billion, according to a court document provided by bankruptcy tracker Chapter 11 Dockets. In February of this year, Bittrex's US subsidiary laid off 80 people, and announced in March that it would close all operations by the end of April. In mid-April, the U.S. Securities and Exchange Commission (SEC) filed a lawsuit against Bittrex and its CEO, accusing it of operating a national stock exchange, brokerage and clearinghouse without registration.
