Poolin, once ranked as the world's largest Bitcoin mining pool, has filed for Chapter 11 bankruptcy protection in the United States amid ongoing financial difficulties. The petition was submitted by Poolin along with two of its subsidiaries to the New Jersey District Court, indicating that the financial troubles stemming from the 2022 liquidity crisis have escalated to a critical stage. The filing places Poolin among a series of major cryptocurrency industry entities that entered bankruptcy proceedings following the market turmoil of 2022, a period that also saw the collapse of firms such as Celsius Network, BlockFi, Voyager Digital, and FTX.
Debt Overview
Court documents reveal that Poolin's total liabilities stand at approximately $173.1 million. The largest portion — $163.7 million — consists of Invoices for Debt (IOUs) that were issued to Poolin Wallet users after the company suspended withdrawals in 2022. At that time, users were unable to access assets held in their wallets, prompting the company to issue IOU instruments representing their outstanding claims.
Asset Sale Plan
As part of the bankruptcy proceedings, Poolin intends to sell two Bitcoin mining facilities located in western Texas. According to the court filings, the initial bid for these two facilities totals $52 million. The amount ultimately distributed to creditors will depend on the proceeds generated from the sale, subject to the court's final approval. Notably, the $52 million initial bid falls significantly short of the $173.1 million in total liabilities, suggesting that unsecured creditors may recover only a fraction of their outstanding claims unless additional assets or restructuring arrangements are identified.
Company History
Founded in 2017, Poolin grew rapidly during a period of intense expansion in Bitcoin mining. By 2019, the company had ascended to the position of the world's largest Bitcoin mining pool, controlling a substantial share of the total transaction verification power on the global Bitcoin network and becoming one of the most influential entities in the industry. Poolin was founded by former Bitmain executives, and its rise coincided with a broader shift of mining operations out of mainland China following regulatory crackdowns, with many firms relocating to regions such as North America.
The 2022 Crisis
The sharp downturn in the cryptocurrency market during 2022, combined with declining mining revenue and mounting liquidity challenges, severely impacted Poolin's operations. That same year, the company halted user withdrawals — a move that triggered widespread concern across the investor community. Bitcoin's price decline from approximately $47,000 at the start of 2022 to below $17,000 by year-end compressed mining margins industry-wide, while rising energy costs further pressured operators.
Restructuring Outlook
Industry experts note that the Chapter 11 process affords Poolin an opportunity to restructure its obligations without entirely ceasing operations. However, the final recovery for creditors remains contingent on the sale proceeds from the Texas mining facilities and any restructuring plan the court ultimately approves.
Analysts emphasize that this development underscores the broader importance of financial sustainability within the cryptocurrency mining sector, where sharp fluctuations in market conditions can place even well-established companies under severe financial strain. The outcome of Poolin's restructuring will be closely watched by affected wallet users and industry observers, as it may set a precedent for how similar cases involving suspended withdrawals and IOU instruments are resolved in U.S. bankruptcy courts.
