Poolin, once among the world's largest Bitcoin mining companies, has filed for Chapter 11 bankruptcy protection in the United States, adding to a series of financial setbacks across the cryptocurrency mining sector after years of pressure on profitability.

The Singapore-based company and its affiliated entities filed voluntary Chapter 11 petitions in the U.S. Bankruptcy Court for the District of New Jersey on July 22. The restructuring is intended to support an orderly sale of substantially all assets while the company winds down operations. Court filings show that Poolin had already stopped mining activities before seeking bankruptcy protection.

Financial Pressure Mounts

The bankruptcy filing reflects the extended difficulties Poolin has faced since the cryptocurrency market downturn and the broader decline in mining profitability. According to court documents, the company has significant liabilities and is operating with only a limited workforce to preserve assets and assist with the restructuring process.

Factors cited in connection with the bankruptcy include continued deterioration in Poolin's cryptocurrency mining business, weakness in its wallet and lending operations, long-running financial pressure after industry-wide market volatility, and higher operating costs alongside weaker mining economics. The April 2024 Bitcoin halving, which reduced block subsidies from 6.25 BTC to 3.125 BTC per block, further compressed revenue for miners across the sector, adding to the structural challenges already facing companies like Poolin that had taken on debt during the previous bull cycle.

Poolin had previously gained international prominence as one of the largest Bitcoin mining pools, at points ranking among the top five globally by hashrate share. Its business later came under strain during the crypto bear market. The company's financial problems became more visible in 2022, when its wallet platform suspended withdrawals, creating uncertainty for customers and undermining confidence in the business.

Asset Sale Planned

As part of the Chapter 11 process, Poolin plans to seek a court-supervised sale of its remaining assets, including mining infrastructure in Texas. Reports indicate that the restructuring is aimed at maximizing value for creditors while bringing the company's operations to an orderly conclusion.

The bankruptcy highlights continued consolidation in the Bitcoin mining industry, where companies have had to contend with volatile cryptocurrency prices, rising network difficulty, and higher energy costs. Although Bitcoin has recovered significantly from earlier market lows, many miners that took on substantial debt during the sector's expansion continue to face financial pressure. Poolin's filing follows other high-profile restructuring cases in the sector, including Core Scientific's 2022 Chapter 11 filing, from which that company emerged in early 2024 after a court-approved reorganization. The wave of distress underscores how the industry's capital-intensive model—requiring ongoing investment in specialized hardware and cheap power—has tested even well-funded operators as competition for block rewards intensifies and margins thin.
