Bitmine, one of the largest publicly traded cryptocurrency mining firms, has acquired 20,500 Ether (ETH) from Galaxy Digital in an over-the-counter transaction, pushing its total Ethereum treasury toward approximately 10 million ETH — nearly 5% of the entire circulating supply, according to data from Etherscan and company disclosures.
Deal Structure and Pricing
The transaction was executed as a private OTC trade, a common method for large institutional blocks to avoid slippage on public order books. Neither Bitmine nor Galaxy Digital disclosed the exact price per ETH, but based on the prevailing market rate at the time of the deal — approximately $3,800 per ETH — the purchase is valued at roughly $78 million. Galaxy Digital, a crypto financial services firm led by Mike Novogratz, regularly facilitates such block trades for institutional clients.

Concentration of Supply Raises Questions
With Bitmine’s Ethereum holdings now approaching 5% of the total 120 million ETH supply, the concentration of tokens in a single corporate treasury is notable. For context, the Ethereum Beacon Chain staking contract holds about 34 million ETH, and the Ethereum Foundation controls roughly 0.3%. Bitmine’s position makes it one of the largest known non-exchange ETH holders.
This level of accumulation reduces the available supply on exchanges, which can amplify price volatility during periods of high demand. However, it also raises concerns about centralization risk if a single entity holds a significant share of a network’s native asset.

Bitmine’s Broader Treasury Strategy
Bitmine has been diversifying its corporate treasury beyond Bitcoin for the past two years. The firm began accumulating Ethereum in late 2023, citing staking yields and the growth of the Ethereum ecosystem as key drivers. In its most recent quarterly filing, Bitmine reported $1.2 billion in digital assets, with ETH now comprising the majority.
The company has also deployed a portion of its ETH into liquid staking protocols, generating additional yield on its holdings. This strategy mirrors moves by other public miners and tech firms seeking to generate returns on idle treasury assets.
Market Implications
The Bitmine-Galaxy trade comes amid a broader trend of institutional Ethereum accumulation. Data from CoinShares shows that Ethereum-focused investment products saw inflows of $2.1 billion in the first quarter of 2025, outpacing Bitcoin products for the first time. The upcoming Pectra upgrade, which will introduce account abstraction and improved scalability, has further fueled institutional interest.
Ethereum’s price has remained relatively stable around $3,800–$4,000 range in the days following the transaction, suggesting the market absorbed the news without significant disruption.
Frequently Asked Questions
Why did Bitmine buy such a large amount of ETH?
Bitmine is expanding its corporate treasury strategy to include significant Ethereum holdings, likely for long-term investment, staking yield, or operational use within its mining ecosystem.
How does this purchase affect Ethereum’s market supply?
With Bitmine’s treasury approaching 5% of total ETH supply, the purchase reduces available exchange liquidity, which could contribute to upward price pressure if demand remains steady.
What is Galaxy Digital’s role in this transaction?
Galaxy Digital acted as the seller, facilitating a large over-the-counter trade to avoid moving the market on public exchanges. The firm regularly provides liquidity for institutional crypto transactions.
Is this purchase a sign of institutional confidence in Ethereum?
Yes, large-scale acquisitions by entities like Bitmine signal strong conviction in Ethereum’s long-term value proposition, particularly as staking and layer-2 adoption grow.
