Bitmine’s Massive Ethereum Buying Spree: How Tom Lee’s Elegant Treasury Strategy Works

Bitmine Immersion Technologies (BMNR) just bought more than 100,000 ether (ETH) coins last week, worth roughly $230 million at current prices.

That’s a statement of conviction from the Ethereum-focused treasury company. Bitmine now controls nearly 5 million ether… and has staked more of it than any other entity on Earth.

The strategy behind that accumulation is one of the most elegant wealth structures I’ve seen in 30 years of watching markets. Yet almost nobody outside of ultra-high-net-worth (“UHNW”) circles is talking about it, even though this strategy is straight out of the wealth playbook.

Today, I’ll talk about what that strategy is… how UHNW individuals have been using this secret to their advantage… and how you can do the same.

Bitmine Through the Years: From Mining Rigs to Ethereum Treasury

Bitmine started in 2019 under a different name. It cycled through identities – including Sandy Springs Holdings and Renewable Energy Solution Systems – before settling into its role as a blockchain technology firm.

Its goal was to run immersion-cooled Bitcoin mining data centers. (Immersion cooling was a genuinely clever piece of engineering that floods computer circuitry with a fluid that helps dissipate heat. It’s a major investment… one that few miners take on.)

Then, on June 30, 2025, the company announced a $250 million private placement and a full strategic pivot to Ethereum accumulation. The stock jumped more than 100% from the open to market close that day, even though it has been impossible to mine ETH for years.

Tom Lee, Bitmine’s chairman, has been direct about the thesis. “ETH is the wartime store of value,” he told CoinDesk in April 2026. As of Monday, April 20, the company holds 4,976,485 ETH, worth roughly $11.9 billion at current prices, and it has staked 3,334,637 of those tokens.

“Bitmine has staked more ETH than other entities in the world,” Lee continued. “At scale…the projected ETH staking reward is $330 million annually… Annualized staking revenues are now $221 million.”

That last number is the one worth sitting with. You see, through ETH staking, Bitmine is able to earn consistent income…

Why Ethereum Earns Yield, While Bitcoin Doesn’t

Mining Ethereum is over. A software upgrade known as “The Merge” in September 2022 ended proof of work (“PoW”) mining on the Ethereum network and slashed daily issuance of new ether coins by roughly 88%.

What replaced it was proof of stake (“PoS”), and with it came something Bitcoin has never offered: native yield.

Staking means that you “lock up” your crypto assets onto a blockchain network – agreeing not to trade or sell them over a given time period – in exchange for rewards. In the simplest terms, it works like this: You stake your ETH, which helps validate the network, and you collect 2.8% to 3.4% annually.

More than 36 million ether, representing more than 30% of the total supply, is now locked in staking contracts earning these kinds of returns.

That yield exists because Ethereum isn’t just a digital currency. It’s the whole infrastructure layer for a financial system… And the people who secure that infrastructure get paid for it.

Then there’s the supply side. This is where Ethereum gets genuinely strange in the best possible way – and it’s why Bitmine is attracted to this cryptocurrency…

What ‘Ultrasound Money’ Actually Means

In August 2021, Ethereum Improvement Proposal EIP-1559 introduced a burn mechanism into the network’s operations.

First, you must understand that to use the Ethereum Network, you need to pay for your use… with a little ETH. And every time you do, a little of your fee gets burned – meaning a portion of every transaction fee on the network gets destroyed permanently.

Thirteen months after the burn mechanism launched, the Merge collapsed new issuance, which investors like us call inflation.

So, the network both generates new coins and burns a portion of the older coins as they are used. As you might guess, this is a sure way to control supply. But it’s even smarter than simply “out with the old and in with the new”…

That’s because the network’s fees are variable. They go up when the network is congested, and they go down when it’s not. Put those two things together, and you get a monetary system that responds to its own activity level. When the network is busy, fees rise, more ether burns, and supply shrinks. When activity slows, the burn rate drops, and issuance resumes at a low level.

I talked more about this here, saying:

The underlying instrument responds to its own utilization rate to manage its own scarcity… It’s a self-adjusting monetary instrument.

Here is where I want to pause and say something directly to anyone who has ever had to sit through an economics lecture about stagflation…

Stagflation is one of my least favorite words in finance. It describes a situation where growth is flat, and prices are still rising. That is structurally impossible inside the Ethereum model.

When monetary pressure is tied to actual utilization, you cannot have stagnant growth and rising money supply at the same time… because stagnant growth means low fees, which means low burn, which keeps inflation minimal. It’s a feedback loop.

The result is a step beyond sound money. Ethereum investors call it “ultrasound money.” It’s inherently deflationary.

Is Ethereum perfectly deflationary right now? No. The reasons are a little technical, so bear with me…

In 2024 and 2025, network upgrades dramatically reduced Layer-2 data costs. They also collapsed base fees and, with them, the burn rate. As of April 2026, Ethereum supply sits around 120 million tokens with mild annual inflation near 0.23%. The deflationary periods return during high activity.

In other words, the current mild inflation is a temporary state within a system built for the opposite.

No other major asset in history actively argues against its own inflation. Even gold, a famously low-inflation hard asset, has a new annual supply of 2%, or nine times the inflation of Ethereum, according to the World Gold Council.

The Self-Repaying Loan: What UHNW Investors Do With This

Here is where the strategy gets elegant. Staking ether earns you yield. That part is straightforward. And we’ve talked about the income Bitmine expects to bring in, thanks to its staking yield.

Sophisticated investors can combine that yield with a specific financial move. It’s borrowed from traditional private banking… and supercharged by Ethereum’s native smart-contract infrastructure.

The mechanics work like this:

• You deposit your staked ether, or its liquid-staking equivalent, as collateral into a decentralized finance (“DeFi”) loan.

• You borrow against that collateral.

• The staking yield continues to accrue on your underlying position.

The loan is executed by smart contract, which means it works autonomously. The terms of the agreement are written into code, with no need for a third party.

So over time, your yield pays down the loan… without you ever writing a check, selling a token, or – most likely – triggering a taxable event (although you’ll want to consult your tax professional on this).

In DeFi, we call this a “self-repaying loan.” You borrowed against an asset… and the asset paid off its own debt.

Ask yourself honestly: What other asset in the history of the world does that, and does it this well?

Real estate generates rental income that can service a mortgage, but you also need tenants, maintenance, property managers, and accountants. Dividend stocks pay quarterly, but borrowing against them is costly, and the margin rates far exceed blue-chip dividend yields. Gold earns nothing while it sits in a vault. Bonds pay their own coupon, but you can’t always borrow against a bond and have the coupon retire the loan with the mechanical elegance you get here.

With ETH, the smart contracts are native to the same network that the asset lives on. There is no middleman interpreting the arrangement. The code executes exactly as written, every time, without a lawyer… without an escrow agent… and without anyone’s permission.

Investors who did this homework 18 months ago are now sitting on collateralized positions that are paying themselves off autonomously, on-chain, at 2.8% annually… All while they hold an asset whose supply architecture trends toward scarcity.

Now, the main risk here is real, and worth naming. Cryptocurrency prices fluctuate hard and fast. That’s why some “self-repaying loan” investors opt to borrow ETH priced in ETH against their staked ETH asset, thereby eliminating liquidation threats. But prices will move up and down while you’re holding the asset.

This is not a strategy for anyone who cannot tolerate that volatility or who takes a larger position than they can afford to lose during a downturn.

This has implications for Bitmine, too. First, there’s no evidence that Bitmine has borrowed against its Ethereum holdings. The firm has stated plainly that it sees the opportunity as generating yield from accumulating more ether, staking it, and holding it.

That said, Bitmine is currently sitting on paper losses of billions of dollars from its average acquisition cost, and Ethereum is trading well below its all-time high near $4,950 set in August 2025.

Lee has said he views this as a buying opportunity, not a crisis. You can agree or disagree with his view… But the math on what Ethereum actually is doesn’t change because the price went down.

The Big Questions Worth Asking Yourself

If you hold ETH, are you earning yield on it? If you’re earning yield on it, are you using that yield passively or putting it to work? And if you’re borrowing against it, is the structure actually retiring the debt by paying it down with your yield, or are you just creating risky leverage?

The self-repaying loan isn’t magic… And it isn’t just for the very rich.

It’s simply the combination of a productive asset with programmable money. Our 21st-century financial plumbing made it possible.

The UHNW crowd figured this out first. The rest of the market is still catching up. But you can benefit from it – once you know how it works.

Good investing,
