NEW YORK, May 9 ― Cryptocurrency exchange Bittrex Inc filed for bankruptcy protection yesterday, three weeks after the US Securities and Exchange Commission (SEC) accused it of operating an unregistered securities exchange.

Seattle-based Bittrex ceased operations in the United States on April 30, and it said the bankruptcy filing would not impact Bittrex Global, which serves customers outside the United States. The company's non-US operations are based in Liechtenstein.

Bittrex's assets and liabilities were both between US$500 million (RM2.2 billion) and US$1 billion, according to a bankruptcy petition filed in Wilmington, Delaware court.

Bittrex said that it was still holding crypto assets of US customers who did not withdraw funds before April 30.

Those assets are "safe and secure” and Bittrex said it intended to ask the bankruptcy court for a limited re-opening of customer accounts so that the crypto could be distributed back to customers.

Several companies in the crypto industry have tumbled into bankruptcy over the past year, felled by a drop in asset prices, renewed regulatory scrutiny, and in the case of the once-prominent exchange FTX, criminal charges.

The SEC sued Bittrex on April 17, alleging that former CEO William Shihara encouraged crypto asset issuers seeking to make their tokens available on the company's platform to delete public statements that could lead regulators to investigate those token offerings as securities.

Bittrex has denied the SEC's allegations, saying the crypto assets on its platform were not securities or investment contracts.

While the SEC's lawsuit remains pending, Bittrex had previously agreed to pay US$29 million in fines to the US Treasury Department for "apparent violations” of sanctions on certain countries and anti-money laundering law.

Bittrex's petition listed the Treasury Department's Office of Foreign Asset Control as the company largest unsecured creditor, with more than US$24 million owed to the agency.

Bittrex's other largest creditors were mostly customers of the crypto exchange. Bittrex listed 16 customers with at least US$1 million in their accounts, without identifying them by name. Bittrex's largest remaining customer account has US$14.6 million in assets, according to the petition. ― Reuters
