Poolin, once the world’s leading Bitcoin mining pool, has filed for Chapter 11 bankruptcy protection in the United States. The move comes after the company faced significant market pressure, worsening liquidity problems, and a sharp downturn in profitability across the crypto mining sector.
From industry leader to bankruptcy proceedings
Founded in 2017, Poolin rapidly grew to dominate global Bitcoin mining pools, offering competitive payout models and large-scale technical infrastructure. In 2019, the company briefly held the largest share of Bitcoin’s network hashrate, establishing its brand as a key force in the mining ecosystem.
Mining pools play a crucial role in the Bitcoin network by enabling groups of miners to combine computational resources, increasing their chances of earning block rewards and ensuring more predictable returns.
Despite this early advantage, Poolin’s position weakened amid persistent challenges. The industry was hit by higher electricity costs, more intense mining competition, and falling Bitcoin prices during bear markets. The crypto downturn in 2022 strained mining companies globally and accelerated the company’s decline.
Poolin, along with two affiliated US entities, submitted bankruptcy filings in the state of New Jersey. The filings list approximately $173.1 million in total liabilities, with a substantial share—about $163.7 million—attributed to IOUs owed to customers through Poolin Wallet.
At its height in 2019, Poolin was the largest Bitcoin mining pool worldwide, yet mounting financial stress and recent liquidity problems ultimately forced the company into bankruptcy court as creditors now await results of the asset sales.
The bankruptcy process will place the company’s remaining assets under court supervision as it seeks to restructure and potentially satisfy obligations to creditors.
2019’s top mining pool succumbed to 2022 liquidity crisis
In September 2022, Poolin suspended withdrawals from its custodial Poolin Wallet service, citing liquidity issues and an urgent need to stabilize operations. The decision impacted both institutional and retail miners who stored Bitcoin and other digital assets via Poolin’s platform.
To address the withdrawal halt, Poolin issued IOU tokens reflecting outstanding balances owed to customers. This measure failed to stem concerns, and the IOUs now comprise the bulk of Poolin’s reported debt, totaling over $160 million.
The company emphasized that preserving assets and developing solutions for affected users were top priorities at the time, but many users remain unable to access their funds.
This episode has renewed debate about the risks of holding crypto assets with centralized providers, as industry participants recall several high-profile collapses linked to custodial failures.
Mini dictionary: IOU (I Owe You) tokens are digital instruments used by some crypto platforms to acknowledge and record debts owed to customers when withdrawals or access to funds are temporarily suspended.
West Texas mining sites to be auctioned
Poolin’s bankruptcy restructuring includes plans to auction two mining facilities in West Texas, setting a combined minimum bid of $52 million. Proceeds from the sale are intended to help repay creditors and maximize recovery under Chapter 11 protection.
Texas emerged as a major global destination for Bitcoin mining operations after China’s 2021 regulatory crackdown led many mining firms to relocate. The state attracted industry players with its abundant energy resources, deregulated electricity market, and regulatory openness toward crypto ventures.
Despite early optimism, Texas miners have also wrestled with volatile profitability, energy grid reliability issues, and mounting competition for affordable power. Poolin’s decision to sell its Texas assets reflects ongoing industry consolidation, as less capitalized companies struggle to persist against larger and more efficient rivals.
