The Hardware/Software Landscape
The bankrupt crypto lender Celsius is getting a second life for its mining operations. On May 25, 2023, U.S. Bitcoin Corp (USBTC), operating as part of the Fahrenheit coalition, announced it has secured the winning bid to restructure and operate Celsius’s mining division. The deal brings 121,800 application-specific integrated circuit (ASIC) mining machines back online, representing a massive 12.2 exahash per second (EH/s) addition to USBTC’s operational capacity.
The Fahrenheit coalition comprises USBTC, Ravi Kaza, Steven Kokinos, Proof Group Capital Management, and Arrington Capital. The group emerged victorious after multiple rounds of competitive bidding for Celsius’s restructured mining assets. Under the terms of the agreement, Fahrenheit assumes the role of management company for the broader Celsius estate, while USBTC gains exclusive operational control over all bitcoin mining rigs previously held by the bankrupt lender.
This development follows USBTC’s recent string of hosting agreements with five companies — Teslawatt, Marathon Digital, Foundry USA, Sphere 3D, and Decimal Group — covering 150,000 bitcoin miners. The Celsius acquisition effectively doubles the scale of USBTC’s operational footprint, positioning the company as one of the largest publicly disclosed mining operators in North America.
Hashrate and Difficulty
The 12.2 EH/s injection comes at a critical moment for the Bitcoin network. Network hashrate has been surging to all-time highs in late May 2023, with an unidentified mining pool reportedly accounting for 13% of all blocks mined over a 24-hour period, according to data from Mempool. The sudden appearance of a dominant unknown pool alongside USBTC’s plans to bring over 121,000 machines back online signals that the competitive landscape of Bitcoin mining is shifting rapidly.
Each ASIC unit in the Celsius fleet contributes approximately 100 terahash per second (TH/s), aligning with the specifications of modern mining hardware deployed during the 2021-2022 expansion cycle. When fully operational, the fleet’s 12,200 petahash per second (PH/s) output would represent roughly 3-4% of the entire Bitcoin network hashrate, which has been hovering near record levels above 350 EH/s.
However, the difficulty adjustment mechanism will respond to the increased hashrate. As more machines come online, mining difficulty will rise proportionally, compressing profit margins for all participants and forcing less efficient operations to reconsider their position in the market.
Profitability Metrics
The economics of operating the former Celsius fleet depend heavily on Bitcoin’s price, which has been under pressure in May 2023. BTC has fallen below the $26,000 level, hitting an intraday low of $25,890 on May 25 — its weakest point since May 12. The global crypto market cap sits at approximately $1.10 trillion, with total trading volumes surging 36% to $38.14 billion as market participants react to macroeconomic uncertainty.
Under the restructuring agreement, financial terms are clearly defined. Fahrenheit receives an annual management fee of $20 million over a five-year contract, while USBTC collects $15 million annually (net of operating expenses) for supervising the mining division. These fixed fees provide revenue certainty regardless of Bitcoin price volatility, though the overall profitability of the operation depends on efficient deployment and electricity costs at hosting facilities.
With Bitcoin mining revenue per terahash declining alongside the price drop, USBTC will need to optimize energy costs and machine uptime to maintain margins. The company’s existing partnerships with multiple hosting providers suggest a diversified infrastructure strategy aimed at minimizing operational risk.
Environmental Impact
Reactivating 121,800 ASIC machines inevitably raises questions about energy consumption. Modern Bitcoin mining rigs consume between 3,000 and 3,500 watts each at full capacity, meaning the entire Celsius fleet could draw approximately 365-425 megawatts of power when fully deployed. The environmental footprint of this operation depends entirely on the energy mix at USBTC’s hosting facilities.
The trend toward renewable and stranded energy sources in Bitcoin mining has accelerated throughout 2023, with major operators increasingly locating facilities near hydroelectric, solar, and natural gas flare sites. USBTC’s partnerships with companies like Teslawatt, which focuses on energy-efficient mining infrastructure, suggest that the company is attuned to sustainability concerns — though the specific energy sources for the Celsius fleet have not been publicly detailed.
As regulatory scrutiny of Bitcoin mining’s environmental impact intensifies globally, the transparency of USBTC’s energy sourcing for this expanded operation will likely become a factor in public and regulatory perception.
Strategic Outlook
The Celsius mining acquisition represents a broader consolidation trend in the Bitcoin mining industry. As smaller and overleveraged operators struggle through the bear market — evidenced by $232 million in digital asset investment product outflows over five consecutive weeks — well-capitalized companies like USBTC are acquiring infrastructure at discounted valuations.
Michael Ho, CEO of USBTC, emphasized the strategic rationale: “Our specialized expertise and track record of execution ultimately secured Fahrenheit’s successful bid to restructure Celsius. Each member of the coalition brings extensive experience operating, optimizing, and scaling high-potential assets across Web3 markets.”
The coming months will determine whether USBTC can efficiently bring the full Celsius fleet online while navigating a challenging macroeconomic environment. With the U.S. debt ceiling stalemate ongoing and crypto markets under sustained selling pressure, operational efficiency rather than price appreciation may be the key driver of profitability for this massive mining deployment.

121,800 ASICs coming back online is massive. 12.2 EH/s is no joke for a single operator
12.2 EH/s from celsius alone. combined with the 150K hosting deals USBTC is pushing 20+ EH/s. thats top 5 pool territory
miner_dave 12.2 EH/s from Celsius plus the 150K hosting deals puts them at 20+ EH/s. thats competitive with Foundry and Antpool territory
celsius mining division getting a second life while creditors are still waiting. makes you think about priorities
creditors still waiting while USBTC flips mining rigs for profit. the bankruptcy process rewards operators not victims
creditor_pain this is what bankruptcy looks like in practice. the assets get acquired at discount by well connected operators and creditors get a fraction. story old as capitalism
creditor_pain thats bankruptcy law in a nutshell. operators get paid to wind down, creditors get a letter and a prayer
150K miners across 5 hosting agreements AND 121K from celsius. USBTC is building a mining empire
