Bittrex

Bittrex filed for Chapter 11 bankruptcy in May 2023 after a combination of mounting regulatory pressure and declining trading volumes made the business unsustainable. In April 2023, the SEC filed charges against Bittrex alleging it had operated as an unregistered securities exchange, broker, and clearing agency. In October 2022, Bittrex agreed to pay $24 million to the US Treasury (FinCEN and OFAC) for sanctions violations. These regulatory actions, combined with the broader crypto market downturn following FTX's collapse, led to the company's shutdown.

When Bittrex filed for bankruptcy in May 2023, US customers were given until April 30, 2023 to withdraw their funds before the bankruptcy filing. The company worked with the bankruptcy court to enable customers to access their remaining balances through the claims process. By late 2023, the bankruptcy court approved a plan to return substantially all customer crypto assets. Customers with remaining balances were required to file claims through the bankruptcy court process. Non-US customers of Bittrex Global were handled separately under that platform's own wind-down.

Bittrex did not suffer any major hacks or direct theft of user crypto funds during its operational history. Its downfall was driven by regulatory enforcement actions — the 2022 OFAC/FinCEN sanctions violations settlement and the 2023 SEC charges — rather than a security breach. Bittrex was historically considered one of the more security-conscious US exchanges and was known for listing a wide range of altcoins. The SEC charged that Bittrex had facilitated trading in tokens that should have been registered as securities.

Bittrex faced multiple regulatory enforcement actions in its final years. In October 2022, it agreed to pay $24 million to settle FinCEN and OFAC allegations that it had processed transactions for users in sanctioned countries including Iran, Cuba, Sudan, Syria, and Crimea. In April 2023, the SEC filed civil charges against Bittrex Inc. and its former CEO William Shihara, alleging they had operated unregistered securities exchange, broker, and clearing agency services. The combined regulatory pressure contributed directly to the bankruptcy filing one month later.
