Bitcoin

There is a particular kind of dinner party silence that follows the question of whether one owns any Bitcoin. It is not quite the silence that greets a question about one’s mortgage, but it is adjacent to it — a mixture of embarrassment, evangelism, or studied indifference, depending on who is asked. Few assets in financial history have managed to be simultaneously a punchline, a religion and a rounding error on a pension statement, often within the same household.

What makes this odd is that Bitcoin was never meant to be a dinner party topic at all. It was conceived, in the depths of a financial crisis that had made banks look reckless and governments look complicit, as a piece of plumbing — a way of moving value between strangers without asking a bank’s permission. That it has instead become a cultural Rorschach test, onto which people project libertarian dreams, speculative fever or plain scepticism, says as much about the age we live in as it does about the technology itself.

This essay does not attempt to settle the argument. It attempts, rather more modestly, to explain how we got here, and to give both the faithful and the doubters their fair say.

The story so far

In October 2008, as Lehman Brothers’ collapse still reverberated through global markets, a document appeared on an obscure cryptography mailing list under the name Satoshi Nakamoto. It proposed a “peer-to-peer electronic cash system” that required no central authority to verify transactions, relying instead on a public ledger — the blockchain — maintained by a distributed network of computers competing to solve mathematical puzzles. In January 2009, the first block was mined, embedded with a headline from that day’s Times newspaper about bank bailouts, a small act of editorial mischief that made the project’s politics rather plain.

For its first few years Bitcoin was the province of cryptographers, hobbyists and, notoriously, the users of an online marketplace for illicit goods, which did the currency’s early reputation few favours. Nakamoto himself vanished from public correspondence in 2011, leaving behind no fortune claimed, no interviews given, and an identity that remains unconfirmed to this day — an absence that has only added to the mythology.

The years that followed were marked by boom, bust and repeat, each cycle drawing in a wider audience than the last. Exchanges collapsed spectacularly, most memorably Mt. Gox in 2014, and yet each time obituaries were written, the network kept producing blocks regardless, indifferent to the fate of any exchange or evangelist. Slowly, institutional attitudes shifted: hedge funds began quietly accumulating, then publicly listed companies, then eventually the machinery of Wall Street itself, culminating in the approval of spot exchange-traded funds in the United States that allowed conventional investors to gain exposure without ever touching a digital wallet.

Today the network Nakamoto started continues to run, essentially unaltered in its core rules, securing a market capitalisation above $1.2 trillion and a circulating supply of just over 20 million coins, edging steadily toward its hard-coded ceiling of 21 million — a scarcity that was, from the outset, the whole point.

The case for Bitcoin

The believers’ argument rests, first, on arithmetic rather than sentiment. Unlike currencies issued by central banks, Bitcoin’s supply schedule is fixed and publicly auditable, immune to the discretionary decisions of any monetary committee. For those who have watched successive rounds of quantitative easing dilute the purchasing power of conventional money, this predictability has genuine appeal — a form of monetary discipline that no government has ever voluntarily imposed on itself for long.

There is also the matter of access. In economies where local currencies have collapsed or capital controls prevent citizens moving their own savings, Bitcoin offers a way of holding and transferring value that does not require a bank account or a government’s blessing. This is not a hypothetical benefit conjured for marketing purposes; it has been used, in practice, by people in Venezuela, Nigeria and Argentina navigating currencies that have lost the greater part of their value within a single generation.

Finally, there is the network itself, which has now run for well over a decade without a single successful attack on its core protocol, a track record that engineers tend to find more persuasive than any amount of rhetoric. Its proponents see in this an emerging form of neutral, apolitical reserve asset, one that answers to no single nation and cannot be conjured into existence by decree.

The case against Bitcoin

Sceptics point first to volatility that would be considered disqualifying in almost any other asset marketed as a store of value. An instrument that has, across its history, shed the majority of its value on more than one occasion is a curious candidate for the label “digital gold”, however often that phrase is repeated. The all-time high of $126,198.06 stands as testament to Bitcoin’s capacity for spectacular gains, but also as a marker against which subsequent drawdowns are measured, sometimes painfully.

There are also the unresolved practical questions. Bitcoin remains cumbersome and slow as a means of everyday payment, a limitation its advocates increasingly concede by reframing it as a store of value rather than a medium of exchange — a pivot that some critics regard as moving the goalposts rather than solving the original problem. The energy consumed by the mining process continues to draw environmental criticism, even as an increasing share of that energy comes from renewable or otherwise stranded sources. And the very anonymity that early users prized has made the network a persistent conduit for ransomware payments and sanctions evasion, a reputational cost its defenders would rather not dwell upon.

Perhaps most fundamentally, critics note that Bitcoin produces nothing — no dividend, no earnings, no rent. Its value rests entirely on the collective conviction of those willing to hold and trade it, a form of consensus that has proven durable so far, but whose durability is, by its nature, unprovable in advance.

The bottom line

Bitcoin has, against long odds, survived long enough to force a reckoning with questions it was not originally designed to answer — about what money is for, who gets to issue it, and what scarcity means in a digital age. Whether it ultimately settles into the role of a niche reserve asset, a speculative curiosity, or something closer to the monetary alternative its architects imagined, remains a matter on which reasonable people, including reasonable economists, continue to disagree.
