Every time Bitcoin falls hard, the same old prophecy returns.

This time, it comes from Jeremy Grantham, one of Wall Street’s most famous market bears. The co-founder of GMO has spent decades warning about speculative bubbles, from technology stocks to real estate to artificial intelligence. Now, he has turned his attention once again to Bitcoin.

His prediction is not that BTC will collapse overnight. It is more subtle than that — and maybe more unsettling. According to Grantham, Bitcoin will not disappear in one dramatic crash. It will slowly fade away over years, maybe even decades, as investors lose interest and the world realizes it never had real economic value.

It is a powerful claim because it does not sound like panic. It sounds like decay.

No explosion. No final candle. No single fatal event.

Just silence.

But is Bitcoin really destined to become a financial ghost? Or is Grantham repeating the same mistake traditional investors have made for more than a decade: judging Bitcoin by old-world standards and missing why people continue to value it?

Why Jeremy Grantham Thinks Bitcoin Will Fade Away

Grantham’s argument is built on three familiar criticisms.

First, he says Bitcoin has no intrinsic value. It does not produce earnings like a company. It does not generate rent like real estate. It does not pay interest like a bond. It does not have industrial demand like copper or oil. To him, Bitcoin is mainly a speculative object whose price depends on the willingness of someone else to buy it later at a higher level.

Second, he argues that Bitcoin has failed as a stable store of value. That criticism became especially sharp after BTC lost more than half of its value from its 2025 peak. For Grantham, an asset that can fall so violently during what he considers a relatively strong economic environment cannot credibly be treated as a reliable way to preserve wealth.

Third, he questions Bitcoin’s usefulness in the real economy. People are not widely using it to pay for groceries, settle business invoices or replace traditional currencies in daily life. In his view, if Bitcoin is not a practical payment tool, not a stable store of value and not a productive asset, then its long-term future is weak.

This is the classic traditional-finance case against Bitcoin.

And to be fair, it is not absurd.

Bitcoin is volatile. It does not behave like cash. It is still not used for everyday payments at mass scale in most developed economies. Its valuation is difficult to model with traditional financial tools. And many people do buy it mainly because they expect the price to rise.

That gives critics plenty of ammunition.

But the deeper question is whether those criticisms are enough to prove Bitcoin will disappear.

Because Bitcoin has already survived many moments when intelligent investors said almost exactly the same thing.

Why This Argument Becomes Louder During Every Bear Market

Bitcoin criticism always becomes more convincing when the price is falling.

During bull markets, skeptics sound out of touch. When BTC is climbing, institutions are buying, ETFs are attracting flows and companies are adding Bitcoin to their balance sheets, the death predictions look almost theatrical.

But during bear markets, the mood changes.

A 10% drop becomes a warning. A 30% correction becomes a crisis. A 50% drawdown becomes proof that the whole thing was fake. Suddenly, the old arguments feel new again. Bitcoin is too volatile. Bitcoin has no cash flow. Bitcoin is not used enough. Bitcoin is only speculation.

That is exactly why Grantham’s comments attracted attention.

They arrived during a period of market weakness, when Bitcoin had fallen sharply and investors were already questioning whether the cycle had broken. In that environment, a famous strategist predicting a slow disappearance feels more credible than it would during a rally.

But this is also where analysis becomes tricky.

Bitcoin has always been cyclical. Its history is full of dramatic crashes followed by periods of recovery, consolidation and renewed adoption. That does not guarantee the pattern will continue forever. But it does mean that volatility alone cannot prove extinction.

If volatility were enough to kill Bitcoin, it would have died many times already.

The real issue is not whether Bitcoin can crash. It clearly can. The issue is whether each crash reduces the network’s long-term relevance, or whether each crash simply removes excess speculation before the next stage of adoption.

Grantham believes the first explanation.

Bitcoin believers believe the second.

And the market has been stuck between those two interpretations for years.

The Counterargument: Bitcoin’s Value Is Not Supposed to Look Traditional

Bitcoin’s defenders usually respond with one simple idea: Grantham is using the wrong measuring stick.

Bitcoin was never designed to be a company, a bond or a piece of industrial metal. It does not need earnings because it is not equity. It does not need a central issuer because it is not fiat money. It does not need industrial consumption because its value proposition is monetary, not physical.

The Bitcoin thesis is built around scarcity, decentralization, censorship resistance and global transferability.

There will only ever be a limited supply. No central bank can create more BTC because markets demand stimulus. No government can directly change its monetary policy by decree. No company owns the network. No CEO can dilute holders. No single financial institution can shut it down.

That does not make Bitcoin risk-free.

But it does explain why millions of people see value in it even when traditional investors do not.

For some, Bitcoin is a hedge against monetary debasement. For others, it is a digital bearer asset. For others, it is a way to hold wealth outside the banking system. For others, it is simply the most liquid and battle-tested asset in the crypto market.

The approval of spot Bitcoin ETFs in the United States also changed the conversation. Bitcoin is no longer only held by early adopters, cypherpunks and crypto-native investors. It is now accessible through traditional brokerage accounts and institutional investment products.

That does not prove Grantham is wrong.

But it makes the “Bitcoin will simply fade away” argument harder to defend.

Assets that are truly disappearing usually lose infrastructure, liquidity, developer attention, institutional access and cultural relevance. Bitcoin still has all of those things.

It may be controversial.

But it is not ignored.

Could Bitcoin Still Disappear? Yes — But Not for the Simplest Reasons

A serious analysis should admit that Bitcoin’s survival is not guaranteed.

No asset has a divine right to exist. Bitcoin could lose relevance if better monetary technologies emerge, if regulation becomes extremely hostile, if self-custody becomes too difficult, if mining security weakens over time, if younger generations stop caring about it, or if its volatility prevents broader adoption forever.

It could also suffer from internal stagnation. Bitcoin’s conservative development culture is one of its strengths, but it can also make change slow. If the world demands faster, more private, more scalable or more flexible systems, Bitcoin may need surrounding layers and infrastructure to keep it useful.

There is also the question of narrative.

Bitcoin’s value depends partly on belief — not in the empty sense of hype, but in the deeper monetary sense. Gold also depends on collective belief. Fiat currencies depend on collective belief. National debt markets depend on collective belief. Money itself is a social technology.

If enough people stop believing Bitcoin is worth holding, the price would suffer.

So yes, Bitcoin can fail.

But Grantham’s version of failure assumes that the world will eventually become indifferent. That is the part that remains difficult to prove.

Bitcoin has been declared dead hundreds of times. It has survived exchange collapses, government bans, civil wars over scaling, brutal bear markets, mining crackdowns, fraud waves, institutional skepticism and years of mockery from traditional finance.

Its survival does not make it invincible.

But it does make disappearance a much harder prediction than it sounds.

The Slow Death — or the Long Transformation?

Jeremy Grantham may ultimately be right that Bitcoin does not become the stable global reserve asset its strongest supporters imagine.

Maybe it remains too volatile. Maybe it never becomes widely used for payments. Maybe it loses cultural energy over time. Maybe future generations treat it as a strange speculative relic from the early internet-money era.

That scenario is possible.

But another scenario is possible too.

Bitcoin may not disappear. It may simply change roles.

It may become less about buying coffee and more about treasury reserves. Less about replacing banks directly and more about offering a neutral monetary asset alongside the existing system. Less about daily payments on the base layer and more about long-term settlement, custody, collateral and savings.

In that future, Bitcoin would not need to satisfy every original dream to remain important.

It would only need to keep doing what it already does better than anything else: exist without permission, remain scarce, settle globally and survive.

That is the real tension in Grantham’s prediction.

He sees an asset slowly losing meaning.

Bitcoiners see a network slowly proving endurance.

Only time can settle that debate.

But if Bitcoin does vanish one day, it will not be because someone predicted its death during a bear market.

It will be because people finally stop finding reasons to hold it.

And so far, after more than fifteen years, that has not happened.
