A legendary investor who called the dot-com bubble and the 2008 housing crash just said Bitcoin will “certainly” go to zero. If part of your savings sits in Bitcoin, that is not a headline to wave away — it is worth taking seriously, one charge at a time. He has been this certain before, in 2018, about this same asset. He was right for about a year. Then he was wrong for the next eight. The question that actually settles whether Bitcoin can go to zero is not his track record, and it is not the price. It is a single test he never ran — and once you run it yourself, you will use it on every dollar, stock, and bond you own too.

Who is Jeremy Grantham, and why does his Bitcoin call matter?
Jeremy Grantham is not a stranger with a webcam and a hot take. He co-founded GMO, a Boston asset manager that has run institutional money for decades, and he built his reputation calling two of the most painful bubbles in modern market history before they popped: the dot-com crash and the 2008 housing collapse. When an investor with that record says your savings are in danger, the honest move is to listen — and then check the claim the way you would check any other, rather than taking it on reputation alone.
In a long interview in late June 2026, Grantham called Bitcoin an “unnecessary piece of nonsense” that “facilitates nothing except criminals moving money so they cannot be seen,” and said it will “certainly” go to zero, though it “may take a long time.” A day later on CNBC he called crypto a “useless, speculative mechanism” that would fade “not with a bang, but with a whimper.” That is three separate charges: Bitcoin produces nothing, Bitcoin is mainly a tool for criminals, and Bitcoin will slowly fade to nothing. Each one deserves to be tested on its own, instead of accepted as a package because a famous name said it.
Is Bitcoin a bubble? What happened the last time Grantham made this exact call
This is not the first time Grantham has used the word “bubble” on this asset. In a January 2018 client letter, he called Bitcoin a “true, crazy mini-bubble,” when one Bitcoin cost roughly $15,000. He was right — for about a year. By the end of 2018, Bitcoin had fallen to roughly $3,200, a 79% collapse. A $10,000 position at the time of his letter would have shrunk to about $2,100 by that Christmas. That is the kind of loss that makes a reasonable person swear off an asset forever.
But that same $10,000, left alone through the crash, would be worth roughly $55,000 today at Bitcoin’s recent price near $82,000 — more than five times the original stake, after first losing nearly four-fifths of its value. Grantham was right about the next year. He was wrong about the next eight. That is the trap with any famous forecaster: being early and being wrong look identical for a very long time, right up until they stop looking identical.
He has made similarly dramatic calls on stocks, too. In January 2022 he warned the S&P 500 could fall to roughly 2,500 — nearly half its level at the time — in what he called a “superbubble.” The index did fall, bottoming around 3,577 that October, a real but much smaller 25% decline, before climbing to new highs. None of this proves he is wrong about Bitcoin this time. A forecaster who missed the exact bottom twice can still be right about the direction on a third try. It does mean his certainty, by itself, is not evidence — which is exactly why the charges need to be tested rather than taken on faith.
Charge one: “Bitcoin produces nothing.” True — and beside the point
This is the strongest of Grantham’s three charges, and it happens to be true. Bitcoin pays no dividend, no interest, and no rent. Grantham built his career as a value investor asking one question of every asset: how much cash will this hand me over time, and what is that cash worth today? Run that question on Bitcoin and the answer is zero, every time. Of course he reaches that conclusion. His ruler only measures one thing.
Run the identical ruler on a gold coin. It pays no dividend either. By Grantham’s own logic, gold is worth zero too — yet people have saved in gold for thousands of years, because gold was never supposed to pay anyone. Its job was to still be there, and still be scarce, when it was needed. Now run the ruler on the cash sitting in a savings account. A dollar bill also pays nothing on its own, and it does something worse than simply sit still: it shrinks. A hundred dollars in 1971 buys about what twelve dollars buys today, after more than five decades of the money supply growing faster than the goods it chases. Judging Bitcoin by its lack of dividend is like judging a fire safe by its interest rate — it is the wrong question for what the thing was built to do. Bitcoin was never built to pay you. It was built to answer one specific problem: a money nobody can quietly print more of.
Charge two: is Bitcoin for criminals? What the crime data actually shows
Grantham’s second charge is that Bitcoin “facilitates nothing except criminals moving money so they cannot be seen.” That claim does not survive contact with the public record. Every Bitcoin payment ever made sits on one ledger that anyone on earth can inspect, forever — it is closer to a glass room in the middle of town square than a dark alley. Names are not written on it directly, but the trail of amounts and timestamps is permanent, and once investigators tie one wallet to one identity, that person’s entire history lights up behind them.
Chainalysis, the firm that tracks illicit crypto activity for law enforcement worldwide, published its 2026 Crypto Crime Report with a striking number: illicit activity made up less than 1% of all the crypto transaction volume it could trace in 2025. And of that small illicit slice, Chainalysis found 84% moved through stablecoins — digital dollars issued by a company, with a company behind them able to print more and freeze accounts — not Bitcoin. If criminals have a favorite instrument, the data points at the one with an issuer, not the one without.
Charge three, and the test he skipped: who can make more of it?
Grantham’s final charge is softer than the first two: not that Bitcoin will crash, but that it will fade — slowly, quietly, like a trend people simply stop caring about. That is a real possibility, and nobody can rule it out with certainty; there are no certainties here, only probabilities. But there is one test that actually tells you whether a money is capable of reaching zero, and it is not the price chart. The question is simple: who can make more of it?
Ask that question of everything else in a typical retirement account. The dollars in a bank? The Federal Reserve and the banking system can create more, and do, every year. The shares in a brokerage account? The company’s board can authorize new stock and dilute existing holders whenever it chooses — a normal, legal feature of owning equity. Every new tokenized fund, bond, or digital dollar Wall Street builds has an answer to that question, and the answer is always a person or an institution with the authority to issue more.
Bitcoin’s answer is different. The supply is capped at 21 million coins, enforced not by a company or a board but by thousands of independently run computers that each check every new block of transactions against the same fixed, declining issuance schedule. No executive, no billionaire, and no government can vote themselves more of it. That is the test Grantham never ran, because his ruler was built to measure cash flow, not issuance. Measured by cash flow, Bitcoin is zero — so is gold, so is the fire safe. Measured by who can dilute it, Bitcoin is the one thing in the comparison nobody can touch.

The door out: 21 million, fixed, forever
None of this is a guarantee that Bitcoin’s price goes up from here, and it is not a signal to do anything with your own savings today. A slow fade, exactly as Grantham describes, remains a genuinely possible outcome — probability, never prophecy. What does not move, regardless of who is buying, selling, or predicting its demise this month, is the ceiling itself. Twenty-one million. Fixed. Forever. No company, no server farm, and no famous investor’s opinion gets a vote on that number, which is the one thing every dollar, every stock, and every new tokenized promise in the financial system cannot say about itself.

The invitation, never the shove
Nobody needs to decide today whether Grantham is right or wrong about Bitcoin fading away over the coming years — that outcome is genuinely unknowable from here, and anyone who tells you otherwise is selling certainty markets do not provide. What is knowable right now is which test actually measures the risk he is describing, and which ruler he used instead. A dividend-free asset is not the same thing as a worthless one; gold has been proving that for millennia. And an asset with no issuer is not the same thing as an asset nobody can analyze; the ledger is public precisely so that it can be checked. Run his three charges yourself, apply the test he skipped to everything else you own, and let the math — not his certainty, and not ours — do the deciding.
Educational commentary, not individual financial advice. Bitcoin’s price has historically moved sharply in both directions, including the roughly 79% decline referenced above, and past performance is not a guarantee of future results. Grantham’s remarks are quoted from third-party reporting on his June 2026 interviews; Chainalysis crime-volume figures are that firm’s own estimates, not an independently audited count of all crypto activity.
