  • Bitmine added 44,463 ETH, pushing its Ethereum treasury to roughly 3.41% of circulating supply and beginning large-scale staking.
  • Both moves highlight divergent corporate treasury strategies as crypto price dynamics remain sensitive to liquidity and year-end flows.

Strategy and Bitmine Immersion Technologies moved decisively in late December, reinforcing how corporate balance sheets are increasingly shaping digital asset markets as the crypto price index reflected heightened institutional activity. Strategy disclosed that it purchased 1,229 bitcoin between Dec. 22 and Dec. 28, spending roughly $108.8 million at an average price near $88,568 per coin. The acquisition followed a brief pause and lifted the company’s total holdings to 672,497 BTC, accumulated at an average cost basis of about $74,997 per bitcoin. Funding came from Strategy’s at-the-market equity program, where 663,450 shares of Class A common stock were sold during the same period, generating net proceeds that closely matched the bitcoin outlay. The company had paused purchases the previous week to bolster its U.S. dollar reserves, which now stand at $2.19 billion, underscoring a tactical approach to capital deployment rather than a shift in long-term strategy.

Bitmine Immersion Technologies, chaired by Tom Lee, pursued a different but equally aggressive path on the Ethereum network. The firm reported adding 44,463 ether over the past week, bringing its total holdings to approximately 4.11 million ETH, or about 3.41% of Ethereum’s circulating supply. At prevailing market levels, the Ethereum treasury alone was valued at just over $12 billion, contributing to combined crypto and cash holdings of $13.2 billion as of Dec. 28. Bitmine also confirmed it has begun staking its ether, with more than 408,000 ETH already generating yield ahead of the planned launch of its Made in America Validator Network in early 2026. Lee described year-end tax-loss selling as a source of temporary softness that enabled the firm to accumulate at scale, even as BMNR shares lagged broader crypto price movements and shifts in coin market cap rankings.

Together, the transactions illustrate how corporate actors are increasingly influencing crypto price behavior through balance-sheet decisions rather than short-term trading. Strategy continues to treat bitcoin as a long-duration treasury asset funded through equity markets, while Bitmine is positioning Ethereum as both a reserve asset and an infrastructure stake tied directly to network security and yield. As year-end liquidity conditions and institutional flows ripple through the crypto price index, these contrasting approaches highlight how corporate participation is becoming a structural factor in shaping market depth, valuation, and supply dynamics across major digital assets.
