Diplômé de Sciences Po Toulouse et titulaire d'une certification consultant blockchain délivrée par Alyra, j'ai rejoint l'aventure Cointribune en 2019.
Convaincu du potentiel de la blockchain pour transformer de nombreux secteurs de l'économie, j'ai pris l'engagement de sensibiliser et d'informer le grand public sur cet écosystème en constante évolution. Mon objectif est de permettre à chacun de mieux comprendre la blockchain et de saisir les opportunités qu'elle offre. Je m'efforce chaque jour de fournir une analyse objective de l'actualité, de décrypter les tendances du marché, de relayer les dernières innovations technologiques et de mettre en perspective les enjeux économiques et sociétaux de cette révolution en marche.
Social media has become much more than just simple exchange platforms. Today, they are the battleground of an ideological clash between freedom of expression, content moderation, and user engagement. Every modification to the rules governing these digital spaces sparks passionate debates, and X (formerly Twitter) is no exception. Recently, Elon Musk announced a revamp of X's algorithm, which aims to prioritize educational and informative content at the expense of those deemed too negative. According to him, this update addresses a central issue: some posts encourage excessive consumption of the social network without truly enriching users' experiences. However, this decision has quickly provoked criticism. Many users denounce a risk of control over information and question the criteria that will define "negativity." Some see it as a form of masked censorship, while others view this change as an attempt to influence how debates are organized on the platform.
Inflation in the eurozone continues to receive close attention as markets monitor the release of December's figures. According to FactSet estimates, consumer prices are expected to rise by 2.4% year-on-year, up from 2.2% in November. This increase, although moderate, raises questions about the path the European Central Bank (ECB) is set to take. On one hand, some investors are betting on a rapid monetary easing, convinced that inflation will gradually return to the ECB's target of 2%. On the other hand, the sustainability of underlying inflation at 2.7%, fueled by rising prices of services and food products, urges the central bank to exercise caution. As the ECB prepares for its first meeting of the year on January 30, the balance between supporting the economy and controlling prices looks particularly delicate.
The Solana network is undergoing an unprecedented expansion phase, driven by massive adoption of memecoins and a significant rise in speculative activity. However, this dynamics raises questions within the community of project founders on the Blockchain. According to a survey conducted by Blockworks Research, 76% of them believe that memecoins play a beneficial role in the ecosystem, while 16% consider artificial intelligence (AI) agents to be an overrated technology. These results reflect an increasing gap between two major trends: on one side, the enthusiasm for highly volatile assets, and on the other, skepticism regarding new AI applications in Web3.
The Bitcoin network has just reached a historic milestone, achieving a record hashrate of 1,000 exahashes per second (EH/s) on January 3, 2025. This symbolic threshold represents an unprecedented acceleration of computing power mobilized to secure the blockchain, as the mining sector undergoes a phase of strategic expansion. Over the span of a year, the network's hashing capacity has doubled, increasing from 510 EH/s in January 2024 to this unprecedented level, illustrating the scale of investments in the industry.
The center of gravity of the global economy is gradually shifting towards new alliances. In the face of the waning influence of Western institutions, another bloc is consolidating its power. Since January 1, 2025, the BRICS have taken a new step by welcoming nine partner states. This expansion, decided at the Kazan summit in October 2024, reinforces their political and economic weight and broadens their grip on emerging markets. Now, the organization represents 51% of the global population and generates 40.4% of global GDP in purchasing power parity.
As digital innovations profoundly transform our habits, Elon Musk is preparing to take a significant step with the launch of X Money. This payment system, directly integrated into the X platform (formerly Twitter), could redefine the standards in the realm of digital payments. A recent code leak, revealed by a researcher, has reignited rumors of an imminent launch, well ahead of the officially announced date for this year, 2025. If this information is confirmed, X Money promises to introduce unprecedented features, particularly the potential support for cryptocurrencies like Bitcoin and Dogecoin. Through this project, the X platform aims to become a key player in digital transactions, raising questions about its economic and regulatory impact.
Cryptocurrencies, once considered a marginal phenomenon, have gradually established themselves as a central element of the global financial ecosystem. This major shift is illustrated by a promising new perspective. Matthew Sigel, head of research at VanEck, stated that the likelihood of an ETF (Exchange-Traded Fund) on Solana being approved in the United States during the year 2025 is high, but exceeds current forecasts. Sigel asserts that Polymarket's 77% estimates underestimate this potential, a statement that reignites the debate on the future of crypto derivatives and their role in transforming financial markets. This statement comes as institutional investors and U.S. regulators attempt to balance innovation with legal frameworks. In this context, the eventual approval of a Solana ETF could significantly broaden access to the crypto market, attracting both capital and institutional players. If these projections materialize, they would mark a significant milestone in the integration of these assets within traditional portfolios.
Since January 1, 2025, the French real estate sector is entering a new era. The changes go beyond a simple revision of previous rules. They reflect a political will to strengthen ecological requirements and adapt the tax framework to an uncertain economic context. The ban on renting energy-rated G housing, for example, embodies this priority given to the energy transition. At the same time, major fiscal upheavals, such as the end of the Pinel scheme or the postponement of the Zero-Rate Loan, are redefining incentives for investors and households. Finally, the continuation of the "anti-Airbnb law" and the stability of notary fees complete this picture of reforms, where each measure shapes the delicate balance between the expectations of property owners, the needs of tenants, and environmental imperatives. These adjustments, far from being anecdotal, herald a profound transformation of the real estate market.
Decentralized finance (DeFi) continues to demonstrate its potential, and Aave is today one of the most eloquent examples of it. Indeed, the platform has reached $33.4 billion in net deposits, surpassing the record levels of 2021, which marked a major turning point for the crypto sector. This staggering figure is not just a simple statistic, but a reflection of an ever-evolving dynamic. The DeFi ecosystem, driven by technological innovations and growing adoption, is transforming into a credible alternative to traditional financial institutions. In this context, Aave is redefining standards by diversifying its markets and strengthening its offerings, attracting both investors and developers. This performance illustrates the platform's robustness, but also the growing maturity of a sector in search of expansion and security.
Experts at Steno Research forecast that 2025 will mark a major milestone in the history of cryptocurrencies. According to their report, Bitcoin could reach $150,000 and Ethereum $8,000, unprecedented levels. These projections are based on an increasingly favorable regulatory framework, coupled with growing institutional adoption. Meanwhile, economic conditions, characterized by falling interest rates and improving liquidity, bolster growth prospects. The introduction of ETFs dedicated to Bitcoin and Ethereum in the United States, which are expected to attract massive investments, illustrates this positive momentum. As the sector moves towards greater recognition, it may redefine its standards and offer new opportunities for innovation.
In 2024, cryptocurrencies reached a significant milestone with their increasing integration into global financial systems. This year was marked by major initiatives driven by ambitious regulations and large-scale strategic projects. In the United States, the potential adoption of the Bitcoin Act paved the way for discussions on the role of cryptocurrencies in economic sovereignty. In Europe, the MiCA regulatory framework established unprecedented rules to stabilize markets and protect investors. At the same time, Latin America emerged as a key player, with innovative partnerships like that of El Salvador and Argentina, consolidating their position in the face of local economic challenges. These advancements reflect a global movement in favor of the adoption of these assets and outline a new trajectory for the crypto industry and its future implications.
The idea that a central bank could hold bitcoin may seem like science fiction to some, but in Switzerland, this perspective is gradually becoming a reality. Indeed, the country is considering an amendment to its federal constitution to allow the Swiss National Bank (SNB) to integrate bitcoin into its reserves, alongside gold. This initiative, led by a group of crypto advocates, reflects a desire to incorporate Switzerland into a modern and forward-looking financial dynamic.
The world of crypto is set to experience a decisive year, driven by promising innovations and growing threats. Indeed, the potential approval of an ETF based on Solana could mark a significant advancement, providing institutional investors with new access to cryptocurrencies. Meanwhile, the rapid progress of artificial intelligence is redefining trading practices, while similar technologies fuel unprecedented cyberattacks. In this context of upheaval, 2025 stands out as a pivotal year for the industry, where the promises of increased adoption must contend with increasingly complex security risks.
The year 2024 will go down in history as a decisive milestone for Nvidia, an emblematic figure of technological innovation in the era of artificial intelligence. Thanks to visionary investments and strategic advances, the company has reached an unprecedented market capitalization of $3 trillion, consolidating its role as a global leader. This success largely relies on its chips, which equip leading global data centers, and on its CUDA ecosystem, favored by developers. However, this triumph comes with increasing challenges. The rise of ambitious competitors, such as AMD and Broadcom, intensifies the pressure. Moreover, key clients, including Google and Amazon, are actively exploring alternatives to reduce their reliance on Nvidia. These contrasting dynamics place the company at a strategic turning point, where the slightest misstep could redefine the balance of power in the market.
The digital world has become the new battleground for international powers, where each attack can have profound and lasting repercussions. Recently, a major cyberattack struck the systems of the U.S. Treasury, revealing the vulnerability of the technological infrastructures of a state renowned for its defensive capabilities. This incident occurs in the context of intense rivalry between the United States and China, as Washington accuses presumed hackers backed by Beijing of being behind the intrusion. For its part, China firmly rejects these accusations, labeling them as unfounded and denouncing a smear campaign orchestrated by U.S. authorities. More than just a mere digital incident, this case sheds light on the growing geopolitical tensions around cybersecurity and the difficulty of identifying those responsible in an increasingly interconnected world.
