Cryptocurrencies, Bitcoin and the Questioning of Official Currencies

Cryptocurrencies, and Bitcoin in particular, are part of a major contemporary debate on the nature of money and the role of institutions. Cryptocurrencies indeed represent an attempt to found an alternative to traditional currencies. To properly understand what these new assets propose, and what differentiates them from official currencies, we must rethink the essence of money, the role of institutions, and trust. It is therefore useful to undertake a deeper reflection that addresses not only economic questions but also anthropological and political philosophy issues, by analyzing the fundamental differences between the libertarian school and the institutionalist school. 

A cryptocurrency is a digital currency whose transactions are recorded and verified by decentralized technology, often blockchain. Bitcoin, which appeared in 2009 (that is to say, notably, right after the great financial crisis), is the first cryptocurrency to have achieved significant success. Its founding principles are decentralization, the absence of a central authority controlling the creation or regulation of the currency, limited supply, transparency, and transaction immutability. 

The founders of Bitcoin promoted this currency for several reasons. First, it would protect against inflation of the money supply and monetary manipulation: unlike official currencies, which are created by banks and regulated by central banks, Bitcoin relies on a fixed and predetermined protocol, without the intermediary of a financial institution. Second, it offers more individual freedom and autonomy, giving the user anonymity and independence from a national currency and its constraints. It also introduces the notion of algorithmic trust: instead of relying on an institution, one trusts the technology and the distributed consensus of the network. Finally, it can promote financial inclusion in areas where access to banking services is limited. 

Bitcoins and other similar cryptocurrencies essentially stem from the utopia of a world in which money would no longer be national but universal, valid for all countries and people, transferable securely and without costs. This currency would do without intermediaries; its value could not be manipulated by governments or central banks. It would be tied to private decentralized governance. It would guarantee transaction anonymity, and its guardian would be not a central bank but an algorithm, assumed to be infallible — a form of anarcho-capitalist utopia. In the 1970s, Friedrich Hayek and the Austrian school recommended denationalizing money, removing the monopoly of money creation from governments and leaving this task to private industry. In a way, the development of cryptocurrencies could be an attempt to fulfill this desire. 

The differences with official bank money are therefore fundamental. Modern money is always, upon issuance, a debt of the issuer (a bank in this case) to itself. But this private debt must be recognized by society to be universally accepted as a liberating means of payment — that is, a means of payment that frees the holder from the debt created by the exchange. Modern money is issued by banks, no longer in proportion to gold or silver holdings, but based on economic development. Money is created from credit, which simultaneously results in the creation of a deposit for the borrower. This deposit appears as a liability for the bank. It is legally a debt of the bank to the deposit holder. Bank deposits thus serve as money because they are accepted by society as a liberating means of payment (unless there is a collective loss of confidence in the bank’s solvency). Credits therefore make deposits. Today, banks create money ex nihilo — no longer linked to precious metal holdings but according to credit demand and economic needs. Moreover, this system is regulated by an external institutional authority — the central bank — since the automatic regulation of money creation by the convertibility of money into gold or silver has disappeared. 

It was the severe recurring financial crises in the second half of the 19th century that led to the creation of official institutions, central banks, after repeated bank failures. Central banks, by homogenizing the monetary space (e.g., one dollar issued by one American bank always equals one dollar issued by another) and by acting, if necessary, as lender of last resort, created the possibility of stability. The usefulness of institutions and rules thus became clear. 

Bank money — which is therefore a bank debt — regulated by central banks and governments relies on confidence in these institutions. Trusting money therefore means trusting the effectiveness of the debt settlement system. And the money supply, backed by credits to the economy, evolves primarily with the economy’s needs. 

Bitcoin and other cryptocurrencies, by contrast, have a limited, pre-fixed supply, independent of economic needs. Not backed by any official institution but by a protocol, and having no economic counterpart, they are highly volatile and their value is completely self-referential. Bitcoin, for example, is worth only what buyers and sellers agree it is worth, with no external objective reference such as the economy, and with no external regulation. Their legal framework is also uncertain. Their universal adoption therefore remains very limited. 

From an anthropological and political philosophy perspective, it becomes clear that the libertarian school’s ideas about the role of institutions illuminate the choices of “Bitcoiners.” They promote cryptocurrencies as a response to institutions deemed dangerous or oppressive by nature. They thus create a new non-official alternative “institution”: a set of rules coded in a protocol, norms, and a trust system based on technology rather than the state. Libertarians believe institutions are artificial constructs that hinder human self-organization. Institutionalists, however — along with thinkers like René Girard — view institutions as the product of spontaneous societal evolution, representing historical learning aimed at improving social efficiency and peaceful coexistence. 

Institutionalists see institutions as deep and resilient social structures. They encompass formal rules such as laws, contracts, or central banks, and informal norms like customs or shared beliefs. They are the “rules of the game” that structure social interaction, enable effective cooperation, strengthen mutual trust, and reduce transaction costs and conflicts. Without them, markets, economic life, and social peace would be unstable or chaotic. Girard, specifically, sees institutions as regulators of violence, developed through human history to channel societal tensions. Money itself plays a role in organizing exchanges and maintaining social order. 

Thus, Bitcoin — a private money not backed by a public institution and issued without reference to society’s evolving needs — cannot be validated universally as a liberating means of payment. Its self-referential value and high price volatility make everyday use as a payment method very difficult. 

However, institutions themselves are not immutable; they can become ineffective or distorted. If, for example, monetary constraints were suspended for too long — such as through sustained public debt monetization — confidence in the debt settlement system and in money itself could be undermined, potentially leading to economic and societal collapse. Money is, as Michel Aglietta said, “the alpha and omega of society” — the fundamental social bond. 

Cryptocurrencies, including Bitcoin, could thus establish themselves as alternative or even substitute money if debt levels relative to GDP continue rising globally and if fears of “corruption” of official money through sustained monetization take hold. Otherwise, their characteristics make them highly speculative assets whose value depends solely on market participants’ anticipations of each other’s future behavior — speculation “in a void.” They are not money, and we should be cautious about letting them become so.

A 20-Point GDP Gap with the United States: Europe Is No Longer Falling Behind — It Is Settling into Decline

For almost twenty years, Europe has been falling behind — not as the result of a temporary cyclical shock, but as the outcome of a cumulative and structural process. The comparison with the United States is now unambiguous: while the U.S. economy regained a sustained growth trajectory after the 2008 financial crisis, Europe appears stuck in a regime of persistently low growth, with lasting economic, social, and geopolitical consequences.

Since the global financial crisis, real U.S. GDP has grown at a markedly faster pace than that of the European Union. As a result, the American economy has expanded roughly twice as fast as Europe’s over the period, creating a gap of more than 20 percentage points in GDP.

Growth is not merely an economic variable. It determines fiscal capacity, investment in research, defense, and infrastructure — and therefore, in the long run, global power itself: the ability to protect living standards and uphold one’s values.

A Growing Productivity Divide

The divergence is also visible in GDP per capita. In the early 2000s, Europe stood close to U.S. levels. By 2024, GDP per capita in purchasing power parity terms reached roughly $75,000 in the United States, compared with around $55,000 in the European Union. This gap no longer stems primarily from differences in hours worked, which have remained broadly stable over the past two decades, but from a widening disparity in productive efficiency.

At the heart of Europe’s challenge lies insufficient productivity growth — more specifically, weak total factor productivity gains. These depend on incentives to innovate and take risks, on competitive market structures, and on the capacity to allow new firms to emerge while less efficient ones exit. In other words, on enabling “creative destruction” in the Schumpeterian sense, as formalized in modern growth theory.

Europe has suffered from a chronic deficit in these areas. Since the late 1990s, productivity growth has been significantly lower than in the United States, often close to zero in the euro area.

Innovation tends to be incremental rather than radical; markets remain fragmented; scale effects are limited; and incentives for risk-taking are insufficient.

The weakness of venture capital — particularly at the scale-up stage — combined with burdensome regulation and penalizing tax structures, leads many European start-ups either to sell prematurely or relocate abroad, fueling a silent outflow of technology and talent.

Structural Handicaps

These weaknesses are compounded by structural constraints: energy dependence, persistently higher energy prices than in the United States, critical dependence on rare earths, and chronic underinvestment in defense and key technologies.

The illusion of European “normative power” — the idea that Europe can shape global standards without sufficient industrial and technological leadership — collides with reality: standards ultimately follow market power.

The remedies are well known. They require acting more collectively and more swiftly. Institutional governance is at stake. They involve deepening the single market, particularly in capital, energy, and digital sectors; massively reducing intra-European regulatory barriers; and pursuing a more ambitious and risk-embracing innovation policy.

They also require faster reallocation of resources toward the most productive firms, greater labor mobility, and a decade-long investment effort spanning climate transition, defense, energy, and critical technologies — alongside a substantial upgrade in education and skills.

Ultimately, the issue is not merely economic; it is political. Without stronger and more durable growth — and therefore without the structural reforms that make it possible — neither Europe’s social model nor its ability to shape the global order can be preserved.

Why Europe Is Falling Behind — and How to Accelerate

Olivier Klein
Professor of economics at HEC
February 12, 2026

Over the span of two decades, the European Union’s relative slowdown has turned into a genuine divergence from the United States—and increasingly from China as well. This is no longer a cyclical gap: Europe’s growth trajectory has become structurally weaker, with profound implications for living standards, social cohesion, and the continent’s geopolitical weight.

Since the 2008 financial crisis, average annual growth in the U.S. economy has significantly outpaced that of the European Union. A one-percentage-point growth gap sustained over twenty years results in a GDP difference exceeding 20%, translating into reduced capacity to finance defense, infrastructure, the energy transition, or education. GDP per capita in purchasing power parity terms—once relatively close to U.S. levels in the early 2000s—has gradually drifted away, signaling a relative decline in European living standards.

This divergence comes at a time when the global economic order has shifted from a U.S./Europe bipolarity to a tripolar configuration: United States, China, and the European Union. Economic weight determines not only internal prosperity but also the capacity to fund military power, sustain diplomatic ambition, and shape technical and regulatory standards. Growth, in other words, has become a strategic variable.

An Efficiency Problem, Not a Labor Quantity Problem

One key lesson from recent research is that Europe does not suffer from a lack of capital or from a massive education or skills deficit relative to the United States. Nor has the historical gap in annual hours worked—traditionally lower in Europe—widened since 2000.

Europe’s relative deterioration over the past two decades stems primarily from an efficiency problem in organizing production and innovation. Total factor productivity (TFP)—which measures the ability to innovate, adopt new technologies, and efficiently reallocate resources—has grown much more slowly in Europe than in the United States since the mid-1990s.

The gap is highly sectoral. Europe remains competitive in traditional manufacturing and certain regulated services, but it lags significantly in high-technology sectors: digital platforms, cloud computing, artificial intelligence, and biotechnology. These sectors now concentrate productivity gains and give rise to “superstar firms” that drive overall economic dynamism. The combined market capitalization of major U.S. technology companies far exceeds that of their European counterparts, revealing a deep imbalance in the capacity to create and capture innovation-driven value.

A Schumpeterian Reading: Europe’s Creative Destruction Deficit

To understand this divergence, a Schumpeterian framework—particularly as formalized by Philippe Aghion—is especially relevant. Long-term growth depends on creative destruction: the entry of innovative firms, the exit of obsolete ones, and the rapid reallocation of capital and labor toward the most productive sectors.

Near the technological frontier, this process requires strong incentives for breakthrough innovation, sufficient competition to push incumbents to reinvent themselves, and institutions that accept failure and structural transformation. This is precisely where Europe underperforms.

Stylized facts are clear: since the mid-1990s, TFP growth has been roughly twice as high in the United States as in the euro area, with the gap concentrated in the most innovative sectors (ICT, digital technologies, biotech), rather than across the entire economy.

Politically and socially, Europe shows a marked preference for ex ante protection of existing jobs and firms—through regulation, labor law, and taxation—whereas the United States tends to rely more on ex post compensation for losers, via labor mobility and income-support mechanisms. The result is lower firm entry and exit rates in Europe, more limited sectoral and geographic labor mobility, and therefore slower reallocation toward the most productive activities.

Innovation Institutions: Europe’s Structural Lag

Another key dimension concerns the organization of innovation systems. In economies close to the technological frontier, growth depends less on imitation and more on the capacity to generate and diffuse breakthrough innovations. This requires specific institutions: effective intellectual property protection, competitive markets, deep capital markets, and public agencies capable of financing long-term, high-risk projects.

The United States has, for decades, developed agencies such as Defense Advanced Research Projects Agency (DARPA), ARPA-E, IARPA, and BARDA. These bodies operate with significant autonomy, substantial funding, and high tolerance for risk. Led by program managers from scientific and industrial backgrounds appointed for limited terms, they fund applied research projects with transformative potential, often at the intersection of public needs (defense, health, energy) and private innovation.

This model has played a decisive role in the emergence of technologies that are now ubiquitous: the internet, GPS, advanced semiconductors, and key components of artificial intelligence and biotechnology.

By contrast, Europe has built a fragmented landscape of research institutions and innovation programs, often oriented toward medium-scale projects, with limited tolerance for failure and lengthy decision processes. The difficulty lies in concentrating resources on strategic priorities, taking bold technological bets, and ensuring a smooth continuum from public research to start-ups, innovative SMEs, and large firms.

Energy, Industry, and the Low-Growth Trap

Performance gaps are also explained by real factors such as energy and industrial structure. The European Union remains structurally dependent on energy imports, particularly gas and oil, while the United States has become a net exporter. Recent energy shocks have exposed this vulnerability, durably increasing energy costs for European firms, especially in energy-intensive sectors.

Some national policy choices have compounded the problem: rapid nuclear phase-outs without immediately available decarbonized alternatives, underinvestment in dispatchable generation capacity, and slow development of interconnections. Since energy is a core production input, persistently higher costs weigh directly on competitiveness, industrial employment, trade balances, and investment capacity in other areas such as R&D and infrastructure.

Thus emerges a “low-growth trap”: weak growth, underinvestment, technological lag, and renewed weak growth.

Europe Is Not Doomed to Decline

The diagnosis should not lead to fatalism. The European Union retains considerable structural strengths: high levels of education, world-class universities and research centers, and a dense base of engineers and scientists. Its socio-economic model—social protection, reduced inequality, strong public services—remains widely supported by citizens.

Europe also benefits from stable institutions: rule of law, judicial independence, central bank independence, and robust property rights protection. In a geopolitically fragmented world, such stability is a valuable asset that can attract talent, capital, and firms—provided Europe regains a more dynamic growth trajectory.

Recent history shows that the Union can respond decisively in times of crisis: the creation of the European Stability Mechanism and banking union progress after the euro crisis, joint debt issuance after the pandemic, and renewed emphasis on reindustrialization. Yet such advances are often incremental and slow.

Three Reform Axes to Escape the Trap

  1. Deepen the Single Market.
    Goods markets remain fragmented by national regulations; services markets are far from integrated; capital markets remain segmented. A genuine capital markets union, deeper integration of energy and digital markets, and reduced entry barriers in protected sectors would generate scale effects comparable to those enjoyed by U.S. or Chinese firms.
  2. Reinforce Frontier Innovation Capacity.
    R&D policy must increase overall effort and, above all, create institutions capable of financing long-term breakthrough projects with agile governance and explicit tolerance for risk. Universities, research centers, start-ups, and large firms must be more tightly connected. Venture capital and growth capital must be strengthened. Europe must enable the emergence of new “superstars” in artificial intelligence, semiconductors, health, and low-carbon technologies. More broadly, it must move away from hyper-protection and hyper-regulation—often intertwined—and toward greater acceptance of risk, failure, and the recognition and reward of success.
  3. Redesign the Social Contract.
    If creative destruction is to intensify, it must be socially acceptable. Protection should shift—as in Denmark—from protecting specific jobs to protecting individuals. Flexicurity in labor markets, large-scale lifelong learning, portability of social rights, and stronger income-insurance mechanisms are essential to reconcile economic dynamism with social cohesion.

Europe must move beyond the implicit compromise that trades short-term stability for a gradual erosion of the productive base that finances its social model. The continent’s divergence is not inevitable; it is the consequence of institutional and political choices that can be revised.

The question is not whether Europe should abandon its model, but whether it can equip itself with the institutions of a competitive frontier economy and a sufficiently strong and dynamic productive base to sustain that model in a world of far harsher power dynamics—more technological and more competitive at once.

Only then can Europe continue to shape global standards and remain a consequential actor on the world stage.

Can France still escape its economic and social trap?

Olivier Klein , published by Les Échos , on the 2nd of January, 2026

We know it — or rather, we should know it after so many years trapped in the vicious circle in which our country finds itself. France will not escape the circular chain of causality linking excessive compulsory levies, an employment rate that is too low, and an uncontrolled level of public debt through yet another increase in taxes and social contributions.

Stabilising the debt ratio instead requires a coherent strategy based on effective management of public spending, policies aimed at increasing our growth potential — including a higher employment rate — and a genuine approach to change management, so that all stakeholders understand and adhere to the path we must take to make our model sustainable once again.

Rethinking the rules of Social Security

The greatest margins lie at the very heart of the social model, starting with pensions, the largest item of public expenditure. Raising the average retirement age by one year, combined with greater convergence between public- and private-sector schemes and an active policy to promote senior employment, would make it possible, within a few years, to generate €10 to €15 billion per year (direct effects and those induced by stronger growth), without undermining retirees’ living standards.

It is also necessary to review the rules governing the use of the Social Security system in order to limit moral hazard: sick leave, the consumption of healthcare services and medicines must be organised so as to ensure responsible and solidarity-based use.

Rebalancing rights and duties, strengthening controls where necessary, but also encouraging virtuous behaviour — both in health and in the labour market — is a sine qua non for the sustainability of our social model.

At the same time, better management of public administrations — reorganisation with targeted non-replacement of departures, reduction of administrative overlaps, digitalisation, and redeployment towards frontline services — could yield around €20 billion per year, with a reduction in staff of about 5%, without any reduction in civil servants’ pay.

Several advanced economies have reduced their number of civil servants by 7% to 10% without triggering a slowdown in growth or a decline in the quality of public services.

Acting on expenditure — and employment

But a lasting exit from the French trap depends as much on employment as on expenditure control. A six-point increase in the employment rate, bringing France up to the German level, achieved — beyond raising the retirement age — through a coherent reform of unemployment insurance, the fight against inactivity traps, and a more effective system of vocational training, would generate nearly €60 billion in additional revenue under unchanged tax legislation. That represents a reduction of around 60% of the primary budget deficit.

An increase of roughly ten points in the active population — equivalent to the Dutch level — would even bring the primary deficit down to zero, following a logic of wealth creation rather than additional taxation, which would instead be regressive.

Still, these reforms — assuming they are voted into law — would have to be genuinely implemented. This requires an assertive approach to change management: a clear and intelligible national strategy, well-defined and understandable milestones, appropriate means to achieve them, and incentive systems aligned with the objectives pursued so as to secure the engagement of all.

By combining 1.5 to 2 percentage points of GDP in recurring savings with 1.5 to 2 percentage points of annual revenue linked to higher employment and growth, France could improve its public balance by 3 to 4 points of GDP within a few years. Enough to stabilise public debt — not through inevitable austerity, but through a calm and responsible reassertion of control over our economic and social model.

To procrastinate further — or worse, to move in the opposite direction of what reason and successful international experience teach us — would be to blindly drive the country ever deeper into a vicious circle that tightens day by day.

French Paradoxes

Published in L’Opinion, December 2, 2025

The paradox of the French social model becomes clear in the accumulation of striking figures: according to the latest OECD data, France holds the European record for mandatory levies and public spending, with more than 32% of GDP in direct social transfers. And the consolidated weight of public expenditure far exceeds that of its neighbors—sometimes by nearly ten points of GDP. Yet it seems particularly difficult for public authorities to reduce spending and quite easy to increase taxes, such is the pressure not to touch the former and the almost paroxysmal demand for fiscal justice. One might therefore conclude that it is useless, or even dangerous, to change a model that appears effective and that everyone seems eager to preserve. And yet…

And yet these deep-seated political tendencies fail to confront the rising and unsustainable cost of our model. The deficit has become almost permanent: France posts a significant primary deficit every year, even as the interest burden—thanks to higher rates—has become one of its largest budget lines, and as the public-debt ratio has risen about three times faster than in the rest of the euro area since 2000. This places the country’s ability to finance this societal choice at serious short- and medium-term risk. The Governor of the Banque de France and the IMF now warn of a major sustainability problem, while fiscal room for manoeuvre shrinks as revenues stagnate and the working population declines relative to the number of retirees, owing to demographic trends.

And yet, on the purely economic front, the picture is no more reassuring. The evolution of GDP per capita over the past twenty years shows a gradual French decline relative to more dynamic neighboring countries. While Germany, the Scandinavian countries, and the Netherlands continue to advance, France has been steadily losing ground in the ranking of wealth created per inhabitant. This productive weakening is also evident in the low share of industry in national value added.

And yet 78% of French citizens now consider the level of taxes and social contributions too high (according to the Compulsory Levies Council’s barometer).

The French paradox is also strikingly visible in the perceived effectiveness of public services. Although spending on health, education, and pensions is comparable to or higher than that of other universalist welfare states, the layering of administrative structures, normative inflation, and over-administration undermine the system’s efficiency. The problem is glaring in the hospital sector, where administrative workloads are far higher than in Germany or Nordic countries, without yielding better outcomes for users. The same pattern exists in education, burdened by a heavy organization and struggling to ensure equity, even as international assessments such as PISA and PIAAC now place France at average or mediocre levels compared with high-performing countries across most key competencies. Multiple cost-effectiveness metrics from international organizations place France only in an average—or even poor—position in nearly all domains studied. And the share of citizens who say they trust and are satisfied with their public services stands at 52% in France, versus 66% on average across the OECD. The Compulsory Levies Council’s latest barometer also shows that the share of French people who believe tax money is well used by the state has fallen by 11 points in two years—from 33% to 22%. Should we really avoid changing anything and continue raising taxes and contributions?

The declining effectiveness of French public policy calls into question the sustainability of the social compromise: although the model seeks to protect all citizens through very high taxes and one of the strongest redistribution systems in the OECD, it no longer provides sufficient social mobility—income equality after redistribution is high, but equality of opportunity is far more debatable—nor dynamic growth, nor even efficient and satisfactory public services.

In the absence of structural reform, the continuous rise in public spending is accompanied by growing collective disillusionment. This paradox at the heart of the French model raises questions about its future and heightens the tension between the desire to preserve an ambitious social pact and the need to restore the means to ensure its effectiveness and sustainability over time.

It is time to move beyond today’s unrealistic debates and address France’s structural difficulties head-on. They harm the country’s economic and social health. And without action, sooner rather than later, they will undermine tax consent, the social pact, and national cohesion itself. The apparent paradox could thus swiftly turn into an economic and societal crisis.

Bitcoin in Question: The End of the Dream of a Currency Without a State?

Published in Les Échos , December the 3d , 2025

In early October, and over several weeks, Bitcoin—the emblem of cryptocurrencies and the flagship of a libertarian utopia—experienced a brutal decline: its price fell from nearly €106,000 to €73,000, a drop of about 30% in less than two months, before partially recovering. Over this period, more than $1 trillion in market capitalization vanished from the crypto market as a whole, affecting not only Bitcoin but all major cryptocurrencies such as Ether, Solana, and XRP.

This dramatic volatility highlights the intrinsic fragility of these private, decentralized “currencies,” which rely solely on algorithmic trust rather than on institutional foundations. The dream of a universal, non-national currency able to escape government control had appealed to many advocates of an economy free from state regulation, following in the footsteps of Hayek and the Austrian school. Bitcoin was explicitly designed to counter the monetary manipulation associated with official currencies. The prospect of large, seemingly easy gains also attracted many newcomers.

But this shock exposes the purely self-referential basis of the value of these so-called currencies, which have no underlying economic counterpart—unlike bank money, which is backed by credit to the economy. This makes them hyper-speculative, deeply volatile crypto-assets, whose value bears no relation to real economic needs and is subject to no institutional regulation.

The recent sharp swings thus illustrate a key point: money is never simply a technical object; it is an institutional and social fact. Unlike bank money, which rests on confidence in banks, central banks and states, cryptocurrencies are backed by no “official” institution and therefore depend solely on the collective trust of their holders—trust that can evaporate suddenly. The immediate causes of the decline are multiple: fears of an excessively steep prior rise, reduced expectations of imminent interest-rate cuts in the United States, massive liquidations of highly leveraged positions, risk reduction by institutional investors, and regulatory uncertainty, among others.

Given such volatility, cryptocurrencies cannot impose themselves as a universal means of payment; they remain, de facto, objects of pure speculation, with no objective value external to the crypto market itself. They are therefore highly susceptible to episodes of euphoric exuberance as well as panic and flight. Beyond the philosophical debate between “algorithmic trust” and institutional trust—mirroring the profound differences between the libertarian and the institutionalist schools—the recent sequence marks a return to reality: without the anchoring of institutions, whether visible or invisible, capable of channeling uncertainty and conflict, no currency can sustainably fulfill its role as social and economic mediator, nor ensure the expected stability or efficiency. The promise of Bitcoin and its successors as currencies thus cannot escape the fundamental question faced by any form of money: its universal acceptance depends less on its technology than on its capacity to preserve the trust on which it rests. Failing that, they are nothing more than hyper-speculative objects.

Private currencies can replace “official” currencies only if the latter suffer from profound and prolonged institutional failures—whether state or central-bank failures—leading to a collapse of trust. As of today, the market has reminded us—at least for the moment—that the anarcho-capitalist utopia represented by cryptocurrencies as currencies remains, above all, a utopia.
