One of the largest Ethereum holders in the world has finally started staking its assets, marking a major strategic shift for Bitmine.
Key Takeaways
- Bitmine deposited 74,880 ETH worth $219 million into Ethereum’s proof-of-stake system, signaling the start of its yield-generation strategy.
- The company holds over 4.06 million ETH, valued at more than $12 billion, making it the largest known Ethereum treasury.
- Staking could earn Bitmine up to 126,800 ETH annually, roughly $371 million at current prices.
- The move comes amid reports of $3.5 to $4.2 billion in unrealized losses on Bitmine’s ETH holdings, suggesting staking is a way to offset losses and bolster income.
What Happened?
On December 27, Bitmine made its first Ethereum staking move by depositing 74,880 ETH into the Ethereum validator contract. On-chain tracking by Arkham and EmberCN shows these deposits came from multiple wallets in coordinated batches, a sign of institutional-level execution. This marks Bitmine’s transition from passively holding ETH to actively using it to generate returns.

Bitmine’s Staking Strategy Begins
Bitmine has been known for its massive Ethereum treasury, and with this latest deposit, the firm has officially started staking for yield. This shift reflects a broader trend among large crypto holders to diversify revenue and improve capital efficiency.
- Bitmine’s 74,880 ETH deposit is only a small slice of its total 4.066 million ETH holdings.
- Based on current annual percentage yield (APY) of around 3.1 to 3.2 percent, the company could potentially earn $371 million in rewards if it stakes its full balance.
- Bitmine’s average ETH purchase price is estimated at $3,884, significantly higher than current market levels near $2,927, leaving the firm with billions in unrealized losses.
The ETH was routed through a “BatchDeposit” contract, a method commonly used by institutions to aggregate funds before spinning up validators. This is part of Bitmine’s new infrastructure strategy launched under the Made in America Validator Network (MAVAN) initiative. In November, the company previewed its staking plans, aiming to partner with institutional staking providers to test and scale operations.
A High-Stakes Shift for the Largest ETH Whale
Bitmine’s treasury now exceeds 4 million ETH, accounting for about 3.4 percent of Ethereum’s total supply. The company aims to push that number to 5 percent. It recently added nearly 100,000 ETH in one week, including a $40 million purchase that brought its average cost closer to $2,991 per token.
This decision to stake is not just about income. It also supports the Ethereum network by contributing to its security and decentralization. And while other firms like SharpLink and ETHZilla sold off during the bear market, Bitmine has doubled down, showing confidence in Ethereum’s long-term value.
Still, large-scale staking comes with risks:
- Validator downtime and slashing penalties.
- Operational and custody complexities.
- Changing economic assumptions in Ethereum’s protocol.
Despite these challenges, Bitmine’s first staking operation shows a strong commitment to unlocking passive income from dormant assets.
CoinLaw’s Takeaway
In my experience, when whales like Bitmine start shifting strategy, it’s not just a footnote but it’s a signal. This move tells me that even the biggest holders are looking for smarter ways to put their crypto to work. Staking is not just about interest, it’s about conviction. They’re not panic-selling their ETH at a loss. Instead, they’re leaning in and playing the long game.
I found Bitmine’s launch of MAVAN especially smart. By building their own validator network and testing with partners, they’re laying a solid foundation for scalability. Sure, they’ve got losses on paper. But with staking, they’re flipping idle tokens into an income engine. That’s a bold, strategic pivot, and I expect more institutions to follow.
