Bitcoin : Défis et Opportunités

Jean-Marie Choffray

Dans cet article, Jean-Marie CHOFFRAY (Professeur Ordinaire Honoraire d’Informatique Décisionnelle à l’Université de Liège, PhD-77, Management Science, Massachusetts Institute of Technology) introduit son recent article “Bitcoin : Défis et Opportunités”.

Nier la réalité de bitcoin n’en change pas la nature… Cette courte note a pour objet de fournir au lecteur une première synthèse des principaux Défis et Opportunités engendrés par l’adoption et la diffusion de Bitcoin (avec « B » majuscule, le réseau informatique). C’est une Révolution Technologique dont les conséquences s’observeront dans les décennies à venir. En effet, le dernier bitcoin (avec « b » minuscule, le moyen d’échange) sera produit vers 2140 ! Suivent sept propositions de réflexion et d’action.

Les trois ANNEXES – Le Triomphe de la Vie dans la Victoire de Bitcoin ; Bitcoin est un rêve, un idéal, un espoir ; Mille quatre cent milliards de dollars – offrent au lecteur un complément d’information lui permettant d’approfondir sa compréhension du phénomène et son analyse de la situation actuelle. De nombreuses et excellentes sources d’informations sont disponibles et consultables sur internet, notamment : https://bitcoin.org/fr/ ; Bitcoin Statistics ; Strategy’s Bitcoin for Corporations.

Qu’est-ce que Bitcoin ?

La Technologie Bitcoin comporte deux éléments : (1) une Base de Données Séquentielle qui intègre aujourd’hui (~) 1,5 milliard de transactions irréversibles, incorruptibles et inviolables entre des agents réels et/ou virtuels – robots ? et (2) un Système d’Exploitation Décentralisé (Bitcoin Core) permettant de valider, de sécuriser et d’enregistrer de telles transactions. Un bitcoin est un moyen d’accès à cette base de données, permettant à son détenteur d’effectuer une transaction irréversible, incorruptible et inviolable ; reconnue comme telle par le réseau. Selon l’objet de la transaction, il s’agit donc d’un droit de propriété digital, d’un moyen d’échange et/ou d’une réserve de valeur ; monnaie et/ou capital digital ?

Ainsi, bitcoin est un objet digital qui peut être stocké, accumulé, transféré et/ou vendu. Le nombre de bitcoins émis diminue exponentiellement dans le temps et le dernier exemplaire sera produit vers 2140. Leur nombre est également limité dans l’espace ; le réseau n’en produira jamais que vingt et un millions. (cf. article original de Satoshi Nakamoto : Bitcoin, un système de paiement électronique). La capitalisation boursière actuelle du réseau (~ $2T : deux mille milliards de dollars) en fait le cinquième actif financier mondial. Soit, plus que la capitalisation cumulée des six plus grandes banques mondiales ; de l’ordre de trois fois le total de bilan de la Banque Centrale Européenne ; ou, encore, deux fois le PIB de la Suisse…

Défis et opportunités

On peut considérer aujourd’hui que la Technologie Bitcoin est quasiment indestructible. Sa probabilité d’effondrement total est estimée à moins de 1%. Pour deux raisons : (1) un éventuel dysfonctionnement du réseau n’affecterait que marginalement la base de transactions séquentielle actuelle (i.e. l’histoire exhaustive des transactions cryptées et encodées depuis 2009) et (2) la décentralisation géographique, technologique et financière du réseau garantit la robustesse – fiabilité et validité – de son mécanisme de gouvernance (e.g. Proof of work). Il va donc falloir apprendre à vivre avec bitcoin, qu’on le veuille ou non, qu’on le souhaite ou pas ! Ceci est d’autant plus vrai que plusieurs pays, dont les États-Unis d’Amérique, ont officialisé leur soutien à cette évolution digitale de l’écosystème bancaire et financier (cf. Strategic Bitcoin Reserve Bill).

Propositions de réflexion et d’action

Pour toute entité publique ou privée soucieuse de marquer sa présence dans ce nouvel espace économique, caractérisé par une forte croissance (~ 60%/an) et une volatilité comparable (~ 60%/cycle de 4 ans) :

  1. Contribuer à créer un Centre Interuniversitaire d’intelligence, d’expertise et de compétence centré sur Bitcoin et les technologies annexes ou induites.
  2. Organiser un Symposium Annuel, destiné à rassembler les acteurs du secteur, à diffuser les bonnes pratiques et à susciter l’innovation.
  3. Constituer un Réseau d’Opérateurs (i.e. bitcoin Miners) assurant une présence effective à l’échelle mondiale et sécurisant l’accès aux transactions (cf. mise en place de Mining Pools).
  4. Inviter les entreprises – et toute autre institution dotée de Fonds Propres – à adopter le Standard Bitcoin, en y consacrant (~3-5%) de leur Actif Net.
  5. Destiner les Excédents Énergétiques – sources intermittentes, surplus nucléaire, cycles d’inférence (Intelligence Artificielle) etc. – à la production et au transfert de bitcoins ; au développement technologique – matériels et logiciels – sous-jacent ; et à la création de produits et services nouveaux.
  6. Constitution d’une Réserve Stratégique – régionale et/ou nationale – de bitcoins tendant vers 3-5% de la richesse économique (cf. Senateur C. Lummis).
  7. Émission de BitBonds : emprunts obligataires adossés (~10%) à bitcoin (cf. Andrew Hohns : BitBonds, An Idea Whose Time Has Come)

Behavioral finance

Mahe FERRET

In this article, Mahe FERRET (ESSEC Business School, Global Bachelor in Business Administration (GBBA), 2022-2026) explains the appeal and challenges of behavioral finance when investing.

Introduction

Behavioral finance is a psychological and economic finance field that allows us to understand how investors – individuals and institutions – make financial decisions. Unlike traditional finance, which assumes that investors are rational actors who always make the optimal decisions to maximize profits based on all available information, behavioral finance recognizes that decisions are often influenced by cognitive biases and emotional responses.

As the financial industry becomes more complex, understanding the psychological biases of investor behavior becomes essential. Behavioral finance includes a more realistic human-centered perspective for analyzing market reactions, making it a crucial area of study for academics, investors, and policymakers alike.

History and Theoretical Foundations

Behavioral finance challenges the classical economic model of the “Homo Economicus”, which states that an investor is a fully rational decision-maker. Instead, it builds on theories about cognitive biases, unconscious and systematic errors that occur when people make a decision.

It also challenges classical theories such as the Efficient Market Hypothesis and Expected Utility Theory. These models presume that markets are efficient (stock prices reflect all available information) and that investors act logically. However, evidence from historical events (financial asset bubbles and market crashes) suggests otherwise, with investors having irrational behavior leading to mispricing (an over or undervaluation of the market price) and high volatility, which could result in potential negative return investments.

Overconfidence is one of the most studied biases. This bias leads investors to overestimate their knowledge and ability to make decisions, often resulting in excessive trading and poor returns. On the other hand, confirmation bias influences investors to seek information that supports their preexisting beliefs, sometimes ignoring evidence. Continuing along this path, herding bias reflects the tendency to mimic the actions of the majority, ignoring personal beliefs or individual analysis. This can generate bubble behavior, such as buying simply because of a trend, even when it seems irrational. Finally, among the long list of other biases, the disposition effect can harm long-term returns. Most of the time, investors sell assets that have increased in value to secure gains but keep assets that have dropped in value to avoid facing a loss.

These biases are not just theory and can explain some behaviors as seen in market crisis, where collective overconfidence and optimism fueled risky lending and investment practices.

Case Study: The 2008 Financial Crisis and Cognitive Biases

The 2008 financial crisis is a significant example of how cognitive biases can influence market behavior. While traditional economists tried to explain the irrational behaviors behind the collapse of global markets, behavioral finance offered an explanation: cognitive biases.

The crisis was a result of years of rising home prices in the U.S. housing market, which created a false sense of security. Financial institutions, driven by overconfidence in their risk management and in the fact that housing prices would continue to rise, issued endless subprime mortgages to borrowers with low credit profiles. These loans were then turned into complex financial instruments like mortgage-backed securities (MBS) and collateralized debt obligations (CDOs), sold to investors worldwide.

According to Montgomery (2011), a collective psychological bias led to this irrational behavior. Overconfidence pushed investors and institutions to underestimate the high risk of the defaults and overtrade, while confirmation bias caused them to ignore warning signs and only select information that supported their vision of the future. The investors were also too optimistic about the market, thinking that it would be in their favor, leading to an underestimation of systemic risk (risk that affects the entire financial system).

This chart visually demonstrates the decline of the S&P 500 index during the market crash, illustrating how cognitive biases affect investor decisions. The index reached a high of 1576, marking the peak of the pre-crisis bull market. The market crashed by 57.7% from its peak and lasted for a total a year and a half. As the crisis progressed, panic selling spread rapidly, as a symbol of herd behavior, accelerating the decline and increasing the losses. Many investors also sold off assets at a loss to avoid more losses, despite fundamental research suggesting long-term recovery potential, which can be translated as a loss aversion bias.

These biases all contributed to the formation of a speculative bubble, which exploded when the housing prices began to fall and defaults rose, triggering a global credit freeze and economic recession.

Nudges, a strategy to mitigate biases ?

Behavioral finance offers an explanation for anomalies in market behavior but can also be used as a tool to improve decision-making. Strategies such as “nudges” (Thaler & Sunstein, 2008) could improve structured environments for decision making without restricting individual freedom. By changing the choice architecture, or “organizing the context in which people make decisions”, such as with default options or checklists, biases can be mitigated.

An example of a nudge strategy from “Nudge” (Thaler and Sunstein, 2008) is the use of automatic enrollment in retirement savings plan, such as 401(k)s in the U.S. Traditionally, employees had to opt in to participate in their company’s retirement savings plan. Many did not enroll because they procrastinated or found the process confusing. The nudge would be to change the default option so that employees are automatically enrolled in the retirement plan, but can opt out if they choose. Like in the finance industry, the choice architecture has changed concerning the default option, and this small change led to high increases in participation rates among employees. Changing the choice architecture in the decision-making process could be the solution to minimize cognitive biases and their negative impact on investments.

Why should I be interested in this post?

As a business student, understanding market anomalies—such as overreactions to news or momentum effects—is essential because they reveal limitations in classical finance theories that assume investors are always rational and markets efficient. Real markets often behave differently, with phenomena like speculative bubbles and panic selling challenging these traditional views. Studying behavioral finance offers valuable insights into the psychological factors and cognitive biases that influence investor decisions. This knowledge is crucial for future business professionals, as it helps improve decision-making, risk management, and strategy development in finance and beyond. Recognizing how human behavior impacts markets prepares business students to navigate real-world complexities more effectively.

Selling Structured Products in France

Mahe FERRET

In this article, Mahé FERRET (ESSEC Business School, Global Bachelor in Business Administration (GBBA), 2022-2026) explains the appeal and challenges of selling structured products in France.

Introduction

Structured products are investment products combining traditional assets (stocks, bonds, indexes…) with derivatives (options, futures…) to offer customized returns tailored to an investor’s risk profile.

In recent years, structured products have gained popularity due to persistent low interest rates and increased market volatility. For instance, buffered ETFs reached $43.4 billion in assets in 2024 according to N.S Huang (Kiplinger, 2024). In France, the market has grown significantly, reaching €42 billion in 2023, an 82% increase over two years, showing investors’ interest in higher returns with safety. Sales teams in investment banks actively seek to answer this demand by offering structured solutions to wealth managers, private banks and institutional investors, using payoff strategies and risk scenarios to support which product to choose.

Why Structured Products Appeal to French Investors

These products are particularly interesting for France’s investment culture, known for capital protection and an income preference due to low interest rates and relatively more risk-averse type of investors. The structured products appeal to French investors as they aim to protect the initial investments and offer higher returns than traditional bonds.

Capital protection means that an investor will not lose their initial investment, even if the market is dropping, and will earn a profit if the market performs well. As an example, BNP Paribas offers Capital Protection Notes (CPNs) tied to the S&P500 that guarantees the initial investment amount at maturity and 130% of the average performance of the index if it rises. If the index’s performance is zero or negative, the investor will only receive its capital back, with no additional return. In client meetings, sales professionals use scenario simulations and historical data to demonstrate the potential returns under different market conditions. Another type of structured product that could interest sustainable caring French investors could be an ESG (Environmental, Social, Governance) note tied to a renewable energy index. As an example, an ESG-linked structured product is tied to indices like the Euronext Eurozone ESG Large 80 Index, with a fixed or conditional coupon of 3 to 5% annually and a maturity of usually 5 to 8 years. With the increasing demand for these products, ESG investments are more and more promoted by Sales through a sustainable aspect, especially to family offices and pension funds committed to responsible investing. ESG products include ESG factors while still using traditional assets like stocks, allowing investors to search for both financial returns and positive societal impact. They often include stock from companies with already strong ESG processes, green bonds supporting environmental projects or derivatives linked to sustainability indicators.

Regulatory Environment in France

In France, the Autorité des marchés financiers (AMF) regulates the sales of structured products to ensure fairness and transparency. These products are complex, and regulations like PRIIPs (Packaged retail and insurance-based investment products) require a Key Information Document (KID) to explain them in simple terms. MiFID II (Markets in Financial Instruments Directive II) also mandates clear disclosure of risks and costs. ESG products, in particular, are under scrutiny to prevent greenwashing. It is an important aspect for the Sales team to consider, as they must respect regulatory requirements at every step with the clients, from pre-trade client conversations to post-sale documentation, and integrate it into their sales pitch.

Client Segments and Tailored Offerings

As complex as these products can be, one of their benefits is that they can be tailored to each investor’s profile risk (more or less tolerance to risk). The structured products can be ideal for retail investors needing safe products. A retail investor could be a retiree seeking a complementary source of revenue and would seek a PPN guaranteeing €10,000 principal with a 3% coupon if the CAC 40 stays flat or rises. The product can be chosen according to the risk level and could be a principal-protected note (PPN), for safer investments. However, less risk-averse investors could seek customized high-return options like a Rainbow note (a derivative-based product designed to offer potential returns based on the performance of a basket of assets, often with a focus on the best or worst performers within that basket) and institutions would need complex products for portfolio strategies like a buffered note. A rainbow note is a product linked to at least two assets and answers a diversification benefit, with a growth and stability balance. Sales teams must match the product structure to the investor’s objectives by collaborating with structuring desks (Department of the trading room that creates the structure that best fits the demands of the client) and traders to design personalized solutions. For a pension fund, a buffered note, designed to allow you to earn a return based on the performance of a stock but with a “buffer” to protect from some losses, offers risk management characteristics, with protection against the first 10% of losses on a global equity index.

Benefits

Structured financial products offer several advantages that make them attractive to a wide range of investors. From a sales perspective, they are attractive tools to meet a client’s needs with a lot of advantages. First, they often include capital protection, meaning that even if the underlying asset’s performance declines, the investor’s capital will be preserved at a predetermined protection level. Additionally, these products can provide regular income, but only to the extent that specific market conditions are met during the investment period. Structured products also allow investors to bet on market volatility, meaning that the products’ prices tend to fall when volatility rises. This creates an opportunity to buy low during periods of high volatility and sell when the volatility declines. Furthermore, these instruments both answer the client’s investment preferences and the diversification potential by offering many investment options across different asset classes. Sales professionals often highlight how these products provide a unique combination of stability and performance that standard products cannot offer.

Challenges

Structured products, despite their benefits, also present common obstacles for investors and for the sales team. Sales must be able to clearly explain these risks using simplified language to make it understandable to even non-expert clients. First, there is the issuer’s risk. Since these tools are issued by banks or other intermediaries, there is a risk that the issuer becomes insolvent or unable to meet its obligations, and the investor may not receive their returns at maturity. There is also an underlying risk, as the value of a structured product depends directly on the performance of the underlying asset, which is subject to high volatility. In extreme cases, the product’s value could go to zero if the asset performs poorly. A second aspect is sometimes the lack of liquidity that can be common for such unique products. Although some products are listed and supported by market makers there is no guarantee of continuous availability in the market. Investors may have difficulties buying or selling the product before maturity, which could lead to unexpected losses due to the absence of market participants at the time of the transaction. Finally, the product can be seen as complex because they are multi-layered, combining different asset types (indices, funds) with different payoff conditions and risk levels.

On this graph, each added asset increases the product’s complexity, making it harder to assess risk, performance and transparency. An investor needs then to evaluate each asset but also their own impact within a basket.

Why should I be interested in this post?

As an ESSEC student interested in business and finance, I found that learning about structured products really helped me understand how financial institutions create investment solutions based on different risk profiles. They’re a great example of how finance can combine both protection and performance. For anyone considering a career in sales, asset management, or investment banking, getting familiar with these products is a great way to build practical knowledge and better understand how finance works in the real world.

My internship at NAOS – Internal Audit and Control

Mahe FERRET

In this article, Mahe FERRET (ESSEC Business School, Global Bachelor in Business Administration (GBBA), 2022-2026) shares her professional experience as an internal audit intern at NAOS.

About the company

The NAOS group was founded in 1980 by Jean-Noël Thorel and is a French skincare company headquartered in Aix-en-Provence. The vision of the founder was to create science-based skincare products prioritizing skin health and ecobiology.

The group is divided into three brands; Bioderma, l’Institut Esthederm and Etat Pur, which all participate in developing and marketing skincare products created and manufactured in France, ensuring high-quality standards backed by scientific research.

With its three brands, NAOS operates in over 100 countries, making it a major player in the cosmetics industry.

NAOS’s particularity is that, unlike traditional skincare companies, it focuses on ecobiology, a unique philosophy that views the skin as a living system that interacts with its environment. In other words, the products’ creation will be designed to enhance the skin’s natural ability to adapt, rather than correct it. The group also emphasizes the importance of research and innovation, with a strong community of scientists, dermatologists and researchers to drive its ecobiological objective.

My internship

My 3-month internship after my first year at ESSEC was within the internal Audit department of NAOS, whose mission is to ensure financial and operational compliance across global operations – NAOS’s three brands and international subsidiaries. My first professional experience was particularly interesting in learning how a company operates from the inside and improving risk management.

My missions

During my internship, I was involved in risk management for the Latin America subsidiaries. Through meetings with local teams, I reviewed internal control frameworks to ensure they were up to date and aligned with NAOS’s internal regulations. I contributed to the continuous improvement of internal control systems by identifying gaps in some processes – such as outdated procedures or missing key information – and proposed some recommendations to address them. In that way, I assessed the adequacy and effectiveness of processes related to the accounting and supply chain departments. My part in the analysis helped highlight inconsistencies in the internal control processes and ensured that the LATAM subsidiaries were aligning more closely to compliance standards.

Required skills and knowledge

The different tasks relied on the combination of technical and interpersonal skills in order to understand how a subsidiary operates and avoids risks. I would need analytical skills to analyze data (operational such as inventory, risk reports – incidents, compliance to security regulations…). and evaluate risk in order to identify potential operational and financial risks. Interpersonal skills were also required because the audit department relied on each department’s (Accounting, Research & Development, Supply…) collaboration to explain effectively how they work and verify they were aligned with compliance. It required strong communication skills to assess how departments and subsidiaries worked.

One thing that was difficult for me at the beginning was having to immediately evaluate processes within the firm without knowing how the company was functioning. It took me a few days (even weeks!) to understand the structure of the firm, the internal control framework and audit processes, necessary to ensure compliance and effective risk management.

What I learned

My internship deepened my understanding of how a company functions from the inside and how the internal audit department’s dedication and precision are essential for a company to ensure compliance with regulations. I gained practical knowledge in identifying risks, implementing controls and understanding financial processes (especially supplier accounting) to mitigate risks, especially in the departments I worked on – Accounting and Supply. It was also the first time I worked in a multinational environment where I had to adapt to diverse regulations and cultural contexts, and I enjoyed working with people from different countries.

Financial concepts related to my internship

I present below three financial concepts related to my internship: Risk Mapping, Compliance and Fraud Detection.

Risk Mapping

During my internship, I had to be consistent with risk assessment through risk mapping. It is a systematic process that guided me and my department to identify, assess and prioritize risk controls within the organization. In short, it was a useful tool to visualize risks in terms of likelihood and impact.

The Risk Heat Map helps provide an overview of an organization’s total risk environment at different levels. It is very important for pre-detection risk management, enabling our department to anticipate and mitigate potential risks before it is too late. It supports strategic planning by categorizing risk likelihood (from improbable to Frequent) and by impact (from Negligible to Catastrophic), ensuring compliance with security and regulations, as well as maintaining financial stability and avoiding vulnerabilities across NAOS subsidiaries.

One of my missions was to research risk factors from an additional department of NAOS in the first step before creating the risk map, by first learning how the department worked and how, from their perspective, there were risks that could be avoided before leading to negative consequences.

Compliance

Compliance is crucial for an audit department within an organization like NAOS. It refers to a firm’s adherence to financial regulations, laws and internal policies that govern its operations. This includes national laws, French and foreign laws for NAOS’ subsidiaries, anti-money laundering (AML) but also international regulations to ensure proper conduct and financial reporting integrity.

Compliance is important for maintaining legal and regulatory integrity, protecting NAOS from penalties and protecting its reputation. For multinational firms like NAOS, operating in a diverse regulatory environment means having a deep knowledge of every regulation to avoid fines and support smooth business operations.

During my internship, I participated in compliance monitoring, by learning how a new regulation (Loi Sapin III), that was going to be implemented as of 2025 for all French companies, could impact NAOS’ operations, mainly in France. The law focuses on preventing corruption in companies and public institutions, aligning with international anti-corruption standards. Our role was to estimate which processes to change or implement to meet the law’s requirements.

Fraud Detection

One of the other key goals of internal audit is to improve fraud detection and prevention, in compliance with regulations but also with NAOS’s own internal principles. Through internal controls and processes to identify intentional misrepresentations or misappropriations of assets and implement preventive measures to avoid anomalies.

Without processes to prevent it, fraud can lead to significant losses and financial manipulation. Relating to my internship missions, I assisted the audit department to detect and avoid inconsistencies. I also supported the implementation of standardized controls across subsidiaries such as segregation of duties, meaning breaking down a process so that different persons are responsible at different steps to prevent fraudulent activities.

Why should I be interested in this post?

This internship report is really interesting for any student curious about how companies stay on top of their finances and risks behind the scenes. It gives a real look into the day-to-day work of an internal audit team at a global skincare company, NAOS, showing how they check that everything runs legally across different countries. If you want to understand risk management, compliance, and fraud prevention—key areas in finance and business—this report offers practical insights and examples that bring those concepts to life.
