Poolin bankrupt: Core pays $42M to end Proto ASIC deal
Poolin’s bankruptcy accelerates the shakeout in Bitcoin mining. The Singapore-based pool filed Chapter 11 in New Jersey, reporting $1M–$10M in assets and $100M–$500M in liabilities, after previously freezing withdrawals in 2022 and issuing IOUs to ~11,700 users owed about $164M. Poolin is now seeking to sell two West Texas mining sites with a “stalking horse” bidder aiming for at least $52M.
At the same time, Core Scientific says it will pay $42M to terminate its Proto Global mining hardware (“Proto”) agreement. Core reported a $1.15B net loss for Q2 and is “winding down” mining: only $26.5M (16%) of Q2 revenue came from BTC mining, while mining costs exceeded mining revenue by $11M. Core expects only one or two sites to mine in 2027 and hosted mining operations to end by end-2026. Revenue mix shifted toward colocation/data-center income (up to 77% from 12%), supported by a new AMD partnership to supply 500MW–2.5GW of US AI data-center capacity.
The wider backdrop is weaker mining economics: Bitcoin’s July 25 difficulty fell 0.74% (smaller decline than forecast), and many miners are “pivoting” from ASIC production to AI/HPC data-center contracts. This raises concerns about network security and could contribute to Bitcoin’s first annual difficulty decline since 2009.
Other miners are also repositioning: Ionic Digital (born from Celsius-era mining assets) plans to retain only a fraction of its ASICs for active mining and targets monetization via “digital infrastructure leasing.” Kazakhstan meanwhile plans a 10% state profit share via capped electricity quotas for large miners.
For traders, the key takeaway is that Poolin bankrupt highlights ongoing counterparty and financing stress in Bitcoin mining while the industry shifts toward AI infrastructure—an environment that can still pressure sentiment near-term.
Bearish
Poolin bankrupt and Core Scientific’s $42M Proto termination reinforce a prolonged mining stress cycle: higher default/counterparty risk, lower miner profitability, and continued capacity shutdowns. Historically, periods of miner insolvencies (e.g., prior mining/counterparty collapses in 2022–2023) have tended to weigh on crypto sentiment and increase volatility, even if day-to-day price drivers remain broader macro/liquidity factors. In the short term, traders may expect negative headlines around mining health to cap rallies and encourage risk-off positioning. In the long term, the industry’s pivot to AI/HPC colocation could stabilize certain balance sheets for survivors, but it may not prevent network economics concerns (difficulty trajectory/security narrative) from influencing sentiment. Net effect: bearish bias, with potential for sharp intraday swings if additional filings or operational shutdowns emerge.
