ETFs Sold $643M of Bitcoin — Then Strategy, Coinbase and BitMine Bought Anyway: 5 Numbers That Explain the Split

United States spot Bitcoin ETFs sold $643 million of Bitcoin in a single day on October 30, the largest daily outflow since June. Three days later, the companies that buy Bitcoin for their own balance sheets did the opposite: Strategy bought 811 more BTC, Coinbase revealed its corporate treasury had reached 18,000 BTC, and BitMine added another 8,573 ETH to a stash that now covers almost 5% of all Ethereum. The same market, the same week, two completely different verdicts — and the gap between them tells you more about where crypto goes next than any single price chart.

This is not about one side being right and the other wrong. ETF investors and corporate treasuries play different games with different rules, horizons and pain thresholds. ETF holders can sell in a click when a $6.3 billion hack rattles them. Strategy cannot easily unwind 849,327 BTC, and BitMine cannot quietly exit 6,060,506 ETH. Understanding why each side moved — and what each move cost — is the difference between copying a headline trade and making an informed decision.

Here is the split, in plain numbers, with the traps to watch before you follow either side.

What Actually Happened on November 2

November 2 was a filing day, not a price day. Bitcoin traded near $78,000, recovering from a six-week low near $77,300 struck after Binance disclosed its $6.3 billion hack on October 29. Ethereum traded near $2,290. The headlines, however, came from company disclosures rather than the order book.

Strategy, the company formerly known as MicroStrategy, filed a Form 8-K with the US Securities and Exchange Commission disclosing that it bought 811 BTC between October 26 and November 1 for $65.5 million, an average of $80,846 per coin including fees. The purchase ended a one-week pause and was its largest weekly buy since September 28, when it added 1,665 BTC. Executive chairman Michael Saylor confirmed the move on X, writing that Strategy now holds 849,327 BTC alongside $4.9 billion of USD assets.

The same day, Coinbase chief executive Brian Armstrong announced that its corporate treasury had recently acquired its 18,000th Bitcoin — the company's own capital, not customer custody assets; he gave no price or date. BitMine Immersion Technologies, chaired by Tom Lee, added 8,573 ETH in the preceding week, taking its holdings to 6,060,506 ETH, about 4.9% of supply. Strive, run by Matt Cole, added 124 BTC between October 24 and 30 at about $80,526 each, lifting its stack to 43,124 BTC.

Set against that buying, the ETF picture looked very different. US spot Bitcoin ETFs recorded about $643 million in net outflows on October 30, while Ethereum ETFs saw about $156 million leave. Total Bitcoin ETF net assets had fallen to about $98 billion by October 30, down from a peak of $152 billion in July 2025, according to data cited in market coverage. Binance, meanwhile, reported about $4.72 billion in net customer withdrawals after reopening on November 1, a reminder that the hack's aftershocks were still moving real money.

So the week ended with a paradox: America's most regulated, most liquid crypto products were bleeding, while its most concentrated corporate buyers were adding. Both reactions were rational — they just answer different questions.

The 5 Numbers That Explain the Split

Strip away the commentary and five numbers carry the whole story. Each one answers a different question about who is selling, who is buying, and what it costs them.

The table matters because it stops a lazy reading. Strategy did not "go all in" last week. It spent $208.2 million buying back its own STRC preferred stock — more than three times its Bitcoin spend — and parked another $98.5 million of its stock-sale proceeds in USD cash. Across the last two weekly filings, Strategy put $413.1 million into STRC repurchases since October 19, more than six times the $65.5 million it spent on Bitcoin over the same stretch. The Bitcoin buy was real, but it was not the biggest cheque Strategy wrote that week.

BitMine's number cuts the other way. Adding 8,573 ETH sounds small next to a 6 million ETH stack, but the composition is what matters: 86% of its holdings are staked, worth about $11.8 billion at $2,261 per ETH, generating an annualised staking yield of roughly $358 million, according to company figures reported this week. BitMine is not just holding Ethereum; it is running one of the largest staking operations in the world, and that yield is a genuine revenue line that ETF holders do not get.

Strategy's Strange Priority: Why the Buyback Beat the Bitcoin Buy

To understand Strategy's week, follow the money, not the headline. Strategy sold 1,178,552 shares of MSTR Class A common stock through its at-the-market programme, raising $164.0 million in net proceeds. Of that, $65.5 million went into Bitcoin and $98.5 million went into USD cash. Separately, it spent $208.2 million repurchasing 2,092,035 shares of STRC, its Variable Rate Series A Perpetual Stretch Preferred Stock, at about $99.52 per share.

That ordering tells you where management sees the most urgent risk. STRC is moving to daily dividend accrual, recently approved across four preferred classes with 99.3% of votes cast. Tidying the preferred stack came first; Bitcoin accumulation continued as the smaller line item.

A second signal sits in the filing itself. At Bitcoin near $78,000, Strategy's 849,327 BTC — bought at an average $75,451 — sit only modestly above cost. Its third-quarter net profit of $19.5 billion, up from $2.79 billion a year earlier, was driven by a $20.9 billion operating gain tied to Bitcoin's price during the quarter. That profit is accounting, not cash, which is exactly why the buyback matters: management is tending the capital structure that funds the whole trade.

Strategy also faces a calendar risk unrelated to Bitcoin's price: MSCI publishes its single-asset index list later in November, which could affect whether index funds must hold MSTR. Add the CFO transition — Andrew Kang steps down November 5, with Reza Virasteh taking over in January — and the Bitcoin thesis, while intact, is clearly more complicated than a tweet suggests.

BitMine: Almost 5% of Ethereum, and Most of It Is Working

BitMine's disclosure deserves more attention than it got, because it is a fundamentally different model from Strategy's. Strategy holds Bitcoin, which pays no yield. BitMine holds Ethereum, stakes it, and earns a return for securing the network. With 5,227,037 ETH staked out of 6,060,506 held, BitMine has turned a passive treasury into an income-producing operation worth roughly $358 million a year at current prices and yields.

That yield changes the risk calculation. A company earning hundreds of millions a year from staking can tolerate a falling ETH price longer than one holding a non-yielding asset on borrowed money — provided the yield holds and the price does not fall faster than the income. It also concentrates risk: one company approaching 5% of Ethereum's supply, mostly staked, is a meaningful share of network security.

BitMine's total position — about $14.5 billion across crypto, cash and other investments, including just 216 BTC — shows how single-minded the bet is. This is an Ethereum company in everything but name. When Ethereum fell 16.9% over the past month, nearly triple Bitcoin's decline, BitMine kept buying. Conviction or stubbornness, the difference will only be visible in hindsight.

Coinbase and Strive: The Quiet Accumulators

Coinbase's 18,000 BTC milestone is easy to underrate — Armstrong gave no price, no date, just a post marking Bitcoin's 18th anniversary. But its treasury reaching 18,000 BTC, roughly $1.4 billion at $78,000, is a deliberate decision by the exchange through which much of America buys Bitcoin. It is still small next to Strategy's 849,327 BTC, roughly 4% of total supply: Coinbase is a large holder, Strategy is in a different universe.

Strive's addition is smaller still — 124 BTC for about $10 million — but it matters for the same reason the other buys do: it shows the treasury trade is not a one-company story. Combined, Strategy and Strive bought 935 BTC worth about $72.6 million in the same window. That is a rounding error next to $643 million of ETF outflows, and that ratio is the honest frame. Corporate treasuries did not offset the ETF selling. They did not even come close. They simply refused to join it.

That refusal is the story. ETF investors sell because they can — their product is designed for easy exit. Treasury companies hold because they must — their equity story is the holding itself. Divergence does not mean one side knows something the other does not; their incentives simply point opposite ways in a panic.

What Most People Get Wrong About Treasury Buying

The most common mistake after a week like this is reading corporate buying as a price signal. It is not, or at least not a clean one. Three myths deserve killing before they cost anyone money.

Myth one: treasury buying means the bottom is in. Strategy bought through much of 2025 and 2026 while Bitcoin fell from its October 2025 high near $126,000 to $57,718 on July 1, 2026, and again to the $77,000s this week. Buying by a committed holder tells you about that holder's strategy, not about where the market turns. Companies with a public mandate to accumulate will accumulate into falling markets by design.

Myth two: a treasury stock is a cheap way to buy Bitcoin. Shares like MSTR and BitMine's stock carry their own risks: dilution from at-the-market share sales (Strategy sold 1.18 million new shares last week alone), preferred-stock dividends, management decisions, index-exclusion risk and a premium or discount to the underlying coins that can swing violently. You can be right about Bitcoin and wrong about the stock, and many investors have been.

Myth three: ETF outflows mean institutions have abandoned crypto. The $643 million outflow was the largest since June, but Bitcoin ETF net assets of $98 billion remain enormous, and the same week brought treasury buys, a Swiss spot Bitcoin ETF approval and NYSE tokenisation work. Institutions are not a single actor. Some sold, some bought, some kept building.

The honest summary is narrower and more useful: ETF holders de-risked after a historic hack; treasury companies kept executing pre-committed strategies; neither group's move, on its own, predicts next week's price.

5 Checks Before You Follow the Treasuries

If this split tempts you to buy a treasury stock or add to a crypto position, run these five checks first. They take ten minutes and they filter out most of the expensive mistakes.

• Check the funding source first: is the company buying with cash flow, with new share sales, or with preferred stock? Strategy funded last week's buy by selling new MSTR shares — existing shareholders were diluted to pay for it. Dilution is a real cost, even when the headline says "bought Bitcoin."
• Check the premium or discount next: what are you actually paying per coin through the stock versus buying Bitcoin or an ETF directly? A stock trading far above the value of its coins can fall hard even if Bitcoin rises, as the premium compresses.
• Check the debt and dividend load: preferred dividends, convertible notes and buyback programmes all compete for the same cash. Strategy's $208 million STRC buyback last week is a reminder that the capital structure, not just the coin stack, decides whether the model survives a long drawdown.
• Check your own custody plan: if you want Bitcoin itself rather than a stock proxy, decide before you buy where the coins will live. Our guide to how to buy crypto with PayPal, its fees and cheaper alternatives covers on-ramp costs, and our ranking of the best hardware wallets in November 2026 covers what happens after the purchase — the step the Binance hack made painfully relevant.
• Check what you would do if it halves: Bitcoin has already fallen about 39% from its October 2025 high. If your position halves again, do you hold, add, or panic-sell? Write the answer down now. The investors who lost the most last week were not the ones with the wrong thesis — they were the ones with no plan for a drawdown.

For readers weighing the ETF route instead, our analysis of 100 new crypto ETFs coming in 2026 — and one company holding 85% of the assets explains the concentration risk hiding inside the "diversified" wrapper, and our explainer on what a DEX is, after decentralised exchanges hit a record 23% of spot trading covers the self-custody alternative that gained share precisely because of the Binance hack. And if you wonder how much Bitcoin is even left to buy, our piece on how many Bitcoins are lost forever — and why the real supply is only about 17 million puts Strategy's 849,327 BTC in its proper, startling context: one company holding roughly 4% of everything that will ever exist, and about 5% of what is actually still accessible.

What Happens Next: The Dates That Decide It

The split between ETF sellers and treasury buyers will not resolve itself in a single week. Five dates and decisions will shape whether it widens or closes.

First, the November 3 US midterm elections land during Asian trading hours on Wednesday, with prediction markets favouring Democratic control of both chambers and options traders pricing a short volatility bump — implied volatility on Bitcoin options expiring November 4 sat near 43.5%, versus about 36% for later expiries. Second, the November 6 US jobs report arrives the same week, a data point that has recently moved Bitcoin more than Fed decisions. Third, MSCI publishes its single-asset index list later in November, a direct overhang on MSTR. Fourth, Strategy's CFO transition takes effect in stages, with Kang stepping down November 5. Fifth, the December Fed meeting looms over everything, with markets still pricing the path of rates after the October decision to hold at 3.75% to 4.00%.

Watch flows, not just prices. If ETF outflows turn positive while treasuries keep buying, the panic narrative fades. If outflows persist while treasury buying shrinks — Strategy's 811 BTC was already far below its September pace — the divergence narrows from the other side. Either way, the filings will tell you before the pundits do.

Frequently Asked Questions

Why did Bitcoin ETFs see $643 million in outflows on October 30?

The outflow followed the $6.3 billion Binance hack disclosed on October 29, the largest exchange theft on record, plus a sharp tech sell-off — the Nasdaq 100 fell 3.5% on Friday, its worst day since June. ETF investors, who can exit in one click, de-risked. It was the largest single-day Bitcoin ETF exit since June, per SoSoValue data cited across market coverage.

How much Bitcoin does Strategy own now?

As of November 1, 2026, Strategy holds 849,327 BTC, acquired for $64.08 billion at an average of $75,451 per coin. Its latest purchase added 811 BTC for $65.5 million at $80,846 per coin, funded by selling 1,178,552 MSTR shares for $164.0 million in net proceeds. The holding represents roughly 4% of Bitcoin's total supply.

Why did Strategy spend more buying back STRC than buying Bitcoin?

Strategy spent $208.2 million repurchasing 2,092,035 STRC preferred shares, over three times its Bitcoin spend. The buyback tidies its preferred structure as STRC moves to daily dividend accrual. It is a funding decision, not a verdict on Bitcoin.

How much Ethereum does BitMine hold, and how much is staked?

BitMine holds 6,060,506 ETH after adding 8,573 ETH in the week to November 1, about 4.9% of Ethereum's supply. Of that, 5,227,037 ETH — 86% — is staked, worth about $11.8 billion at $2,261 per ETH, with an annualised staking yield of roughly $358 million, according to company figures.

Is buying MSTR or BitMine stock the same as buying Bitcoin or Ethereum?

No. Treasury stocks add dilution, preferred dividends, management risk, index risk and a premium or discount to the coins. You can be right about Bitcoin or Ethereum and still lose on the stock if the premium compresses or dilution accelerates. Buying coins directly, or via an ETF, is usually simpler.

Does corporate treasury buying mean Bitcoin has bottomed?

No. Strategy and BitMine buy on pre-committed strategies through rising and falling markets alike, including the long decline from Bitcoin's October 2025 high near $126,000. Treasury buying is evidence of conviction, not a timing signal.

Conclusion

The week of November 2 gave crypto two headlines that seem to contradict each other, and both are true. ETF investors sold $643 million of Bitcoin in a day because a historic hack and a tech sell-off gave them reason to reduce risk. Strategy, Coinbase, BitMine and Strive bought anyway because their strategies pointed the other way — and stopping would mean abandoning the story their shareholders bought into.

The useful lesson is not "follow the treasuries" or "follow the ETFs." Different holders face different costs for the same decision, and copying a holder whose costs you do not share is how retail investors get hurt. Check the funding, check the premium, check the custody, and decide in advance what you will do if the position halves.
