Poolin, a Singapore-based operation that once ranked among the largest Bitcoin mining pools in the world, has filed for bankruptcy after years of failing to recover from a liquidity crisis that first surfaced in 2022. The filing marks the formal end of a company that, at its peak, commanded a significant share of the network's global hash rate.
The collapse traces back to mid-2022, when Poolin froze customer withdrawals amid a broader liquidity crunch that swept through the crypto industry following the fall of Terra, Three Arrows Capital, and other major players. Unlike some rivals that eventually restored access to funds, Poolin never fully unwound the freeze, leaving thousands of users locked out of their holdings for years.
Texas Assets on the Auction Block
As part of the bankruptcy proceedings, Poolin is now moving to auction off its remaining physical infrastructure, including mining sites located in Texas. Proceeds from the sale are intended to repay creditors, chief among them roughly 11,700 users who have been holding IOUs since the 2022 freeze without a clear timeline for repayment.
The Texas facilities represent what appears to be the last substantial hard assets tied to the company, and their liquidation signals that Poolin's operators see no path to reviving the business as a going concern. Instead, the bankruptcy process is oriented toward maximizing recovery value for creditors rather than restructuring the pool's operations.
A Fall From the Top of Bitcoin Mining
Poolin's decline stands as one of the more dramatic examples of how the 2022 credit contagion reshaped the mining industry. Mining pools coordinate the computational work of individual miners and distribute block rewards among participants, and a pool's size directly reflects trust from the broader mining community. Poolin's inability to make users whole after freezing withdrawals steadily eroded that trust, pushing miners toward competitors and starving the company of the volume needed to remain relevant.
The episode also underscores the risks custodial mining pools can pose to participants, since miners often route both hash power and accumulated balances through a pool operator, creating counterparty exposure similar to that of a crypto exchange or lender.
What Comes Next
With the bankruptcy filing now public, affected users will be watching the auction process closely to see how much of their outstanding balances can realistically be recovered. Bankruptcy proceedings of this kind often stretch on for months or years, and creditors — including retail miners who contributed hash power in good faith — are typically left waiting well after asset sales conclude before any distributions are finalized.
Poolin's downfall adds to a string of casualties from the 2022 crypto credit crisis that are only now reaching final resolution, a reminder that the fallout from that period continues to work its way through the industry even as bitcoin's price and mining difficulty have since climbed well past pre-crisis levels.
