Crypto exchange Bittrex has filed for bankruptcy in the U.S. state of Delaware on Monday, months after announcing it would wind down operations in the country and weeks after being sued by the Securities and Exchange Commission (SEC).

The exchange believes it has more than 100,000 creditors, with estimated liabilities and assets both within the $500 million to $1 billion range, according to a court filing shared by Randall Reese of Chapter 11 Dockets, a bankruptcy tracker.

Despite Bittrex’s impending exit from the U.S., the SEC sued it in mid-April on allegations it operated a national securities exchange, broker and clearing agency. The SEC also sued former Bittrex CEO Bill Shihara and Bittrex Global. Bittrex Global CEO Oliver Linch said last month that the exchange intended to fight these charges in court, but a bankruptcy proceeding may make this more difficult.

Bittrex is the latest crypto entity to file for bankruptcy, joining fellow exchange FTX and a host of lenders like Celsius, Voyager and BlockFi.
