The recent crypto sell-off is affecting more than token prices — it’s denting corporate treasuries, testing ETF investors’ downside tolerance and exposing how mining depends on power and flexible infrastructure.
BitMine’s ETH paper losses widen
BitMine Immersion Technologies, chaired by Tom Lee, has seen unrealized losses balloon after Ether slid below $2,200. The firm holds roughly $9.1 billion in ETH, including a recent purchase of 40,302 ETH, and those mark-to-market losses have topped $7 billion. While losses remain unrealized unless assets are sold, the hit highlights the risks companies face when treasuries are concentrated in volatile tokens. BitMine’s management has defended the position by noting its balance sheet is intended to track ETH exposure, which naturally carries price swings.
BlackRock Bitcoin ETF holders slip underwater
The downturn in Bitcoin — which traded below $80,000 and then under $75,000 during the sell-off — pushed aggregate returns for holders of BlackRock’s iShares Bitcoin Trust (IBIT) into negative territory, according to industry observers. Bob Elliott, CIO of Unlimited Funds, said the average dollar invested in IBIT is now underwater. IBIT was one of BlackRock’s fastest-growing funds, reaching about $70 billion in assets, and the pullback is giving many investors their first extended lesson in Bitcoin’s downside volatility.
US winter storm slams Bitcoin production
A late-January winter storm in the United States forced many miners to curtail operations, underscoring how mining output remains sensitive to stress on local power grids. CryptoQuant data showed daily production from publicly listed miners averaged roughly 70–90 BTC before the storm, then dropped to around 30–40 BTC at the storm’s peak as facilities reduced load or temporarily shut down. Production recovered as conditions improved. The data covered large public operators such as CleanSpark, MARA Holdings, Bitfarms and Iris Energy, illustrating how sizable US mining facilities react when grid constraints arise.
CoreWeave and the mining-to-AI pivot
CoreWeave’s transition from GPU-based crypto mining to AI and high-performance computing is a prominent example of mining-era hardware being repurposed for the AI boom. Ethereum’s shift from proof-of-work to proof-of-stake diminished GPU mining demand and prompted operators like CoreWeave to pivot into AI services. CoreWeave now functions primarily as an AI infrastructure provider rather than a crypto company; Nvidia’s roughly $2 billion equity investment in the firm underscored market confidence in that model. Other miners, including HIVE Digital, Hut 8 and MARA Holdings, have explored similar diversification strategies, turning mining-built capacity toward AI and cloud workloads.
