This is the question everybody is actually asking, usually somewhere around the second glass of wine, and it deserves a proper answer rather than a hedge dressed up as balance.
Can I tell you what it cost me to learn this? For years, I wanted somebody — anybody, ideally somebody clever and expensive to tell me whether this thing was real. I wanted the answer handed over so I could stop thinking and start doing. And that craving for certainty cost me more than any market ever has, because a person desperate for an answer will accept a bad one from whoever offers it most confidently. What I have since learned is that the ability to hold two contradictory ideas in your head without panicking is not a failure to decide. It is the entire skill.
So let us hold two ideas.
What it has already survived
The list is genuinely remarkable. Mt. Gox, once handling the overwhelming majority of the world’s Bitcoin trading, haemorrhaged around 850,000 coins and collapsed in 2014 — bled slowly over years rather than lost in a night, which is somehow worse. China banned it repeatedly, eventually expelling the largest mining industry on earth; the network’s computing power halved, shrugged, relocated, and returned to record highs. Then came the 2022 winter, in which lenders, funds and one very famous exchange were revealed to be, in the technical phrase, making it up. Billions evaporated.
Through all of it, the protocol itself kept producing a block roughly every ten minutes, indifferent to the carnage around it.
Now — and here is where I must part company with the more enthusiastic literature — that does not mean Bitcoin has never broken. It has, twice. In August 2010, somebody exploited an overflow bug and conjured 184 billion bitcoin into existence, roughly 9000 times the entire supply that will ever exist. Satoshi patched it within five hours, and the chain was rolled back. In March 2013, a software upgrade split the network in two, someone successfully spent the same coins twice, and the fix involved developers ringing up the big mining pools and politely asking them to downgrade, at considerable personal cost.
I find those two incidents more reassuring than the sanitised version, and I’d rather you knew them. Bitcoin’s resilience has never been that it cannot break. It is that when it broke, people who cared fixed it in hours, and the thing kept walking.
What could genuinely finish it?
Four candidates deserve a serious hearing, and I have no interest in waving any of them away.
Quantum computing could, in principle, unpick the cryptography holding the whole edifice together. The developers know, and quantum-resistant upgrades are actively discussed. The honest timeline is measured in decades, and the machines required do not currently exist. Not dismissible. Not imminent either.
The security budget problem is subtler and, to my mind, the most interesting. Miners are paid in two ways: freshly minted coins and transaction fees. The minting halves every four years and eventually stops altogether. At that point, the security of the entire network rests on fees alone — and whether those fees will suffice is a genuinely open question that will not be settled in our lifetimes. Anyone who tells you it’s obviously fine, or obviously fatal, is guessing.
Then competition. Ethereum runs programmable contracts; Solana handles thousands of transactions a second. Bitcoin’s answer — that it never wanted to be a computer, only a store of value — is coherent. It is also a thesis, not a fact, and it requires people to keep believing it.
And regulation. A coordinated effort by major governments to make holding Bitcoin legally untenable would hurt. Enormously. That has become markedly less likely since the American spot ETFs arrived and the custodians moved in; it remains possible, particularly where governments regard control of money as a matter of national survival.
The Lindy effect
Which brings me to the one advantage Bitcoin’s rivals cannot buy at any price: time.
There is an idea, popularised by the mathematician Nassim Taleb and named after a New York delicatessen where Broadway actors argued about which shows would run and which would close. For things that do not perish — books, ideas, technologies, institutions — every additional year of survival increases their expected remaining lifespan. A play that has run for a decade will probably run another. A book still read after two centuries will likely see a third. Fragility gets weeded out by time; what remains has been tested by it. This is the Lindy effect.
Bitcoin has now survived seventeen years, two protocol failures, the loss of its founder, several obituaries per annum, and the concerted hostility of the world’s second-largest economy. Every halving that passes without anyone tampering with the twenty-one million cap makes that cap more credible. Every year without a catastrophic failure makes the next year’s failure less likely. Every institution that adds it to a balance sheet makes the next institution’s decision fractionally easier.
Gold took centuries to accumulate its reputation, through nothing more magical than repeatedly failing to rust. Bitcoin is attempting the same trick at speed, in a world where information travels instantly, and institutions still move like continents.
I’d add one delicious wrinkle, in fairness. Taleb himself, who gave us Lindy, has become one of Bitcoin’s most withering critics. Ideas do not belong to their authors, and the honest reader will notice that the framework’s own father would use it against the very conclusion I have just drawn. Sit with that. It is the whole point of this article.
Where I have landed
Bitcoin is a high-risk, high-volatility asset with an asymmetric shape, and anybody who tells you what it will be worth in five years is telling you something they cannot possibly know. That applies with perfect symmetry to the bulls and the bears; the confidence of the person speaking tells you precisely nothing about the accuracy of what they say.
The case rests on three legs: a supply cap that nothing else replicates, an adoption curve that may be far earlier than the noise suggests, and optionality — the possibility that if the digital gold thesis proves right, even a modest exposure can change the arithmetic of a portfolio entirely. The case against is equally coherent: it produces nothing, earns nothing, and its value depends wholly on a shared belief that could, in principle, evaporate. The very properties that make it thrilling to its admirers are exactly what make it intolerable to a state.
Both cases are strong. Holding both in mind, rather than dismissing whichever is inconvenient, is what separates an investor from a believer — and I have been both, and only one of them sleeps well.
What I do, for whatever it is worth, is treat it as speculative rather than foundational, refuse to let any single position determine whether my family is fine, and give it time rather than attention. Nothing about that is advice, and I’d be suspicious of anyone who offered you some. It is simply the temperament of a woman who has learned, slowly and expensively, that patience is the strategy rather than the thing you do while waiting for one.
Bitcoin is either the most consequential monetary invention since the banknote or the most elaborate collective agreement in financial history. The genuinely remarkable thing is that both sentences describe the same object perfectly.
