The Day Ethereum's Biggest Buyer Ran Out of Reasons to Buy
Co-produced by Daniel Aharonoff and DigitalDan
Ethereum fell off a cliff on Wednesday. In the space of a few hours, ETH plunged more than 6%, knifing through $2,600 like it wasn't even there and bottoming near $2,554. Nearly a quarter of a billion dollars in leveraged positions got vaporized — 95% of them longs, traders who were betting the Glamsterdam rally would keep going.
But the price action, as ugly as it was, isn't even the real story. The real story is what Tom Lee said on a stage in Singapore this morning. As the chief editor of ethdan.me, I've been watching Bitmine Immersion Technologies stack Ethereum week after week for more than a year — the most relentless buyer in crypto. And Lee just told the world the buying spree is about to end.
So here's the question: what happens to Ethereum when its biggest buyer taps out?
What's the Big Deal?
On October 7, Ethereum opened near $2,697, briefly touched $2,699, and then fell to $2,554 — a drop of more than 5.3% on the day. Over a 24-hour window, $232.67 million in ETH positions were liquidated, and $221.18 million of that — just over 95% — were long positions. Translation: almost everyone getting wrecked was betting on the price going up.
But here's what makes this crash different from an ordinary bad day in crypto. Ethereum's single most consistent source of buy-side demand is preparing to walk away. Speaking at TOKEN2049 in Singapore, Bitmine chairman Tom Lee said the company will stop accumulating ETH once its holdings reach 5% of Ethereum's total circulating supply — a hard ceiling on a buying spree that has made Bitmine one of the largest ETH holders on the planet.
"We only need to get another 100,000 ETH to get to 5%," Lee said. "Now we're going to stop."
Let that sink in. The buyer who purchased Ethereum every single week since June 2025 — through every dip, every rally, every bout of panic — is about to hang up the "closed" sign. And at the current pace, there are only about six or seven weeks of buying left.
The $15.5 Billion Buyer: By the Numbers
To understand why this matters, you need to grasp the sheer scale of what Bitmine has done. This isn't some fund that dipped a toe in. This is the most aggressive corporate accumulation of Ethereum in history.
1. 6,016,414 ETH — Nearly 5% of All Ethereum
Bitmine's latest update, published Monday, puts its holdings at 6,016,414 ETH — roughly 4.9% of the 122.1 million tokens in circulation. At Wednesday's depressed price of around $2,580, that stack is worth approximately $15.5 billion. One company. One out of every twenty ether in existence.
2. A Year of Nonstop Buying — Ending in Weeks
"We thought this would take five years," Lee said on stage. "It took us a little over a year. More importantly, we did this all in the middle of a bear market."
He's right about the pace. At Bitmine's recent rate of accumulation, adding the final ~100,000 ETH needed to hit the 5% cap will take roughly six to seven more weeks. After that, the machine stops. Bitmine still holds $643 million in cash and marketable securities it could deploy — more than twice what's needed to finish the job — so there's no funding question here. This is a deliberate, announced exit from the demand side.
3. The Stock Got Crushed Too
The market didn't need a translator. BitMine Immersion (NYSE American: BMNR) shares fell 7.14% to $24.33 on Wednesday as Ethereum declined, underperforming even a brutal day for crypto-linked stocks. Strategy (MSTR) fell 5.7%, Coinbase dropped 4.07%, and Robinhood slid 3.17%. When the whole sector is red and the treasurer-stock is the reddest, the message is clear: investors are pricing in the end of the bid.
The $202 Million ETF Outflow Nobody Is Talking About
Bitmine's exit is happening against an even bleaker institutional backdrop. U.S. spot Ethereum ETFs just stretched their run of daily redemptions to six consecutive sessions — and the latest leg was brutal.
On October 6, BlackRock's iShares Ethereum Trust (ETHA) accounted for the entire $202 million in net outflows on its own, according to SoSoValue fund-flow figures. Two hundred and two million dollars, out the door, in a single day, from a single fund. Over the same session, Bitcoin funds drew $119 million in — money isn't leaving crypto, it's rotating away from Ethereum.
The gap is the clearest driver of ETH's recent underperformance. Ether is down roughly 5.5% while Bitcoin has slipped about 3.2%. The ETH/BTC ratio has slid to 0.031. Institutions are favoring the leading asset, and Ethereum is paying for it.
The bleeding didn't stop — it accelerated. Earlier this week I noted Ethereum ETFs had shed $155 million over four sessions. Then came the $202 million single-day redemption.
Why This Is Happening Now: Three Forces Colliding
Crashes don't need one cause. They need several. Here's what's stacking up against Ethereum this week:
- Demand is evaporating on two fronts: Bitmine's announced buy-ceiling and six straight days of ETF outflows mean the two steadiest institutional bids of the past year are both fading at the same time.
- Leverage got flushed: ETH perpetual futures open interest stood near $47.5 billion — a mountain of leveraged exposure. When price broke $2,600, the long liquidation cascade did the rest, with $221 million in longs forcibly closed.
- Macro is hostile: The 10-year Treasury yield climbed above 5.3%, Brent crude pushed past $101 a barrel on renewed Strait of Hormuz tensions, and the dollar is firming ahead of the Fed minutes. Risk appetite is fading everywhere, and crypto is the first thing sold.
Ethereum is now testing its 50-day simple moving average near $2,546. That line is the last technical defense before a deeper slide — and it cracked intraday before recovering slightly.
Why You Should Care
You might be thinking: Bitmine hits its target, stops buying, so what? They said they'd stop — they're not selling. And that's technically true. But markets don't run on technical truths; they run on expectations. And the expectation priced into ETH all year was that a buyer with a $15.5 billion stack would keep buying, week after week, forever.
There's a deeper lesson here, and it's one the crypto world keeps re-learning: concentrated demand is a double-edged sword. When one buyer accumulates 5% of the supply, every purchase is a tailwind — and every purchase is also a countdown. The bid that lifts the market becomes, in the end, the bid that was always going to disappear. Bitmine didn't exit in panic. It exited by design. And the market still hated it.
Meanwhile, the ETF flow divergence with Bitcoin is the thing to watch next. Spot Bitcoin funds hold $110.8 billion against $17.69 billion for ether funds. When institutions rotate, Ethereum — the "risk-on" crypto — takes the bigger hit. If ETHA's $202 million single-day redemption is a one-off, fine. If it's the start of a rotation, the $2,546 moving average won't hold.
What Happens Next?
Two scenarios, and I won't pretend I know which one wins:
1. The Capitulation Setup
Here's the contrarian read. The Crypto Fear & Greed Index read 74 — "Greed" — as recently as October 6, right before the dump. That's the classic top signal: maximum bullishness, maximum leverage, maximum complacency. The $232 million liquidation flush just reset a huge amount of that froth. Every previous major ETH bottom in this cycle has followed a leverage purge. If $2,546 holds as support, this could be the washout that clears the runway — especially with Glamsterdam progressing toward mainnet and fresh fundamental catalysts on the calendar.
2. The Demand Cliff
Or the darker read: six to seven weeks from now, the most reliable weekly buyer in Ethereum history is gone. ETF flows are rotating into Bitcoin. The 50-day average is cracking. A break below $2,546 opens the door to $2,400 — and then the February lows near $2,000 start entering the conversation. Nothing about this scenario requires panic; it just requires the absence of a bid.
My take? Both can be true in sequence. Short-term flush, medium-term grind. The next two weeks of ETF flow data will tell us everything — watch whether ETHA's $202 million outflow was an anomaly or a pattern.
Final Thoughts
Wednesday was a reckoning for anyone who assumed Ethereum's demand was permanent. It isn't. Bitmine's $15.5 billion buying spree — the single most impressive corporate accumulation this cycle — has an expiration date, and Tom Lee just read it out loud on stage. The ETFs are bleeding. The longs got flushed. And ETH is sitting on its 50-day moving average, deciding what it wants to be.
But here's what I keep coming back to: Ethereum survived the ICO-era whale dumps, the merge FUD, and February's 25% weekly collapse to $2,000. The network keeps shipping — Glamsterdam just went live on Sepolia with 25 EIPs. The question was never whether Ethereum works. It's whether the market's bid was ever as deep as the technology. We're about to find out.
Stay tuned to ethdan.me — I'll be tracking the ETF flow data, Bitmine's weekly updates, and that $2,546 line in the sand every step of the way.
