Cryptocurrencies
I. Introduction
Cryptocurrencies constitute a novel class of digital assets employing asymmetric cryptography to secure transactions and control the issuance of new units, operating within decentralized networks based on blockchain technology or related distributed ledger technology (DLT) solutions. These instruments represent a fundamental innovation in electronic money theory and payment systems, characterized by the absence of a central issuing authority, algorithmically determined monetary policy, and substantial market value volatility.
It should be noted that the term “cryptocurrencies” is used broadly in this Article and will be refined into “crypto-assets” in subsequent sections, as not all digital assets employing blockchain technology aim to function as money or medium of exchange.
The emergence of cryptocurrencies has precipitated profound challenges for legal systems worldwide, requiring reconceptualization of foundational categories in monetary law, securities regulation, tax law, and anti-money laundering frameworks. This Article examines the definitional parameters, taxonomic classification, technological architecture, and evolving regulatory landscape governing cryptocurrencies and related digital assets.
II. Definition and Constitutive Properties
Cryptocurrencies may be defined as digital or virtual currencies secured by cryptographic mechanisms that prevent counterfeiting or double-spending in distributed environments. In contradistinction to traditional fiat currencies issued and controlled by central banks, cryptocurrencies base their operation on cryptographic consensus mechanisms enabling transaction validation without requiring trust in a centralized intermediary institution.
A. Essential Characteristics
The constitutive properties of cryptocurrencies encompass:
Decentralization — in principle, the absence of a single point of control or failure in system architecture, distributing trust across network participants rather than concentrating it in identified intermediaries. In practice, many networks exhibit only partial decentralization due to mining or staking concentration and governance dynamics.
Transaction Irreversibility — at the protocol level, finalized transfers cannot be unilaterally reversed without recipient consent, creating settlement finality that differs fundamentally from traditional payment systems where chargebacks and reversals remain possible. However, off-chain reversals through exchanges and custodians, as well as emergency hard forks under extreme circumstances, represent practical exceptions.
Pseudonymity — cryptographic wallet addresses are not directly linked to users’ legal identity at the protocol layer, though chain analysis techniques may enable partial deanonymization through transaction pattern analysis. Statutory frameworks increasingly treat major chains as de facto analyzable through forensic vendors and travel rule requirements.
Programmability — the capacity to implement complex business rules and transactional conditions through scripts or smart contracts, enabling automated execution of agreements without centralized intermediaries. The degree of programmability varies significantly: Bitcoin’s scripting language is deliberately constrained, while platforms such as Ethereum support Turing-complete smart contract functionality.
Global Accessibility — operation independent of geographic borders and state jurisdictions, creating regulatory arbitrage opportunities and enforcement challenges.
III. Taxonomy and Classification Systems
A. European Union Regulatory Classification
Regulation (EU) 2023/1114 on Markets in Crypto-assets (MiCA) establishes the authoritative taxonomy for crypto-assets within the European Union, introducing three principal categories:
Asset-referenced tokens (ARTs) — crypto-assets purporting to maintain stable value by reference to several fiat currencies, commodities, or other crypto-assets, subject to authorization requirements and prudential standards for issuers. “Significant” ARTs face stricter oversight by the European Banking Authority.
E-money tokens (EMTs) — crypto-assets purporting to maintain stable value by reference to a single fiat currency, regulated analogously to electronic money under existing EU financial services law.
Other crypto-assets — encompassing utility tokens and categories not captured by the foregoing definitions, subject to disclosure requirements and conduct-of-business rules for service providers.
MiCA applies in phases: rules for ARTs and EMTs apply from 30 June 2024, while the general crypto-asset service provider (CASP) regime for other crypto-assets applies from 30 December 2024, with a transition period until July 1, 2026 for existing VASPs. For practical implementation guidance, see Stibbe’s MiCA analysis.
B. Functional Classification Framework
The European Financial Reporting Advisory Group (EFRAG) has proposed a tripartite functional classification for accounting and regulatory purposes:
Payment tokens function as media of exchange and stores of value in economic transactions, approximating the monetary functions of traditional currency.
Investment tokens represent debt claims, equity interests, or other forms of participation in enterprise profits, potentially qualifying as transferable securities under MiFID II depending on the rights attached.
Utility tokens provide access to specified products, services, or functionalities within blockchain ecosystems. While not constituting investment instruments by design, regulators increasingly stress that economic reality and marketing can override nominal design — utility tokens may acquire investment characteristics through market trading and can be classified as securities or investment instruments based on their actual function rather than their label. The ESMA Guidelines on qualification of crypto-assets as financial instruments provide authoritative criteria for this assessment, with Deloitte’s analysis clarifying which crypto-assets qualify. For detailed comparison of regulatory frameworks, see MiCAR vs MiFID II guide and practical guidance on utility tokens under MiCA.
IV. Principal Functional Categories
A. Bitcoin and the Cryptocurrency Archetype
Bitcoin remains the prototypical cryptocurrency, the introduction of which in 2009 by the pseudonymous Satoshi Nakamoto initiated development of the entire digital asset ecosystem. The Bitcoin whitepaper, published on October 31, 2008, implemented the Proof-of-Work mechanism as the first practical consensus protocol in a trustless environment and introduced the concept of deterministically limited monetary supply with an upper limit of 21 million units.
Bitcoin’s significance extends beyond strictly technical aspects, constituting the reference point for the entire cryptocurrency market in terms of market capitalization, institutional adoption, and development of regulatory and technical infrastructure. The approval of spot Bitcoin ETFs by the U.S. Securities and Exchange Commission in January 2024 marked a significant milestone in institutional acceptance. Eleven Bitcoin ETF applications were approved simultaneously, representing what legal analysts characterized as a landmark decision for cryptocurrency markets, with comprehensive market implications analyzed by Chainalysis.
B. Altcoins and Subsequent Generation Innovations
The term altcoins (alternative coins) denotes cryptocurrencies developed after Bitcoin, often introducing significant technological or functional innovations:
Ethereum constitutes the most important second-generation platform, implementing a Turing-complete programming language enabling creation of smart contracts — self-executing programs operating on the blockchain without reliance on centralized intermediaries and with strong resistance to censorship, though not immune to validator-level transaction ordering or community-coordinated interventions.
Cardano and Polkadot represent third-generation systems utilizing Proof-of-Stake mechanisms characterized by substantially increased energy efficiency relative to traditional Proof-of-Work.
Monero and Zcash constitute specialized privacy cryptocurrencies implementing advanced cryptographic techniques (ring signatures, zero-knowledge proofs) for enhanced transaction anonymity, raising particular regulatory concerns regarding anti-money laundering compliance.
C. Stablecoins and Value Stabilization Mechanisms
Stablecoins constitute a specialized cryptocurrency category designed to minimize value volatility through linkage to reference assets with stable valuation. MiCA Regulation introduces particular requirements for stablecoin issuers within the EU, including reserve requirements, redemption rights, and capital adequacy standards.
Fiat-collateralized stablecoins maintain reserves in traditional national currencies. Tether (USDT) and USD Coin (USDC) represent the largest implementations, subject to increasing regulatory scrutiny regarding reserve transparency and actual emission coverage.
Crypto-collateralized stablecoins utilize overcollateralization in other crypto-assets combined with automatic stabilization mechanisms implemented through smart contracts. DAI issued by the MakerDAO protocol constitutes the principal implementation.
Algorithmic stablecoins employ supply adjustment mechanisms without external collateral. Bank for International Settlements research indicates inherent instability as an emergent property of this model. The catastrophic failure of algorithmic stablecoin TerraUSD (UST) in May 2022, which experienced near-total value destruction within days initiating a liquidation cascade of approximately $40–50 billion across the Terra ecosystem, empirically confirmed these theoretical predictions. The MIT Sloan analysis provides detailed examination of the run dynamics, with the NBER Working Paper offering rigorous academic treatment. Chainalysis forensic analysis documents the specific trades that triggered the collapse.
D. Decentralized Finance Tokens
Decentralized Finance (DeFi) represents an ecosystem of financial protocols operating on blockchain infrastructure without traditional institutional intermediaries:
Governance tokens grant holders voting rights over protocol parameters and proposed changes — Uniswap (UNI) and Compound (COMP) constitute prominent examples.
Liquidity tokens represent shares in liquidity pools of decentralized exchanges (automated market makers).
Synthetic assets constitute tokens reflecting the value of external financial assets through collateralization mechanisms and oracle systems providing price data.
According to BIS analysis, stablecoins account for a substantial share of DeFi activity and liquidity, functioning as a key numéraire for valuation and exchange within decentralized protocols.
V. The Question of Intrinsic Value: Cryptocurrencies versus Traditional Stores of Value
A. The Philosophical Challenge of “Intrinsic” Value
A persistent critique of cryptocurrencies holds that they lack “intrinsic value” and therefore cannot constitute legitimate money or stores of value. This critique, while reflecting classical economic perspectives, conflates several distinct concepts warranting careful examination.
Neither gold nor Bitcoin possesses truly “intrinsic” value in the strict economic sense. Gold’s value composition derives from industrial and technological applications (approximately 10% of demand), jewelry and cultural preferences (approximately 50%), and store of value perception including central bank reserves and investment demand (approximately 40%). The critical observation is that most of gold’s value is also based on collective belief and historical convention, not intrinsic utility alone.
B. Comparative Monetary Properties
Both gold and Bitcoin function as stores of value based on specific structural properties. Comparative analysis reveals distinct advantages for each:
Bitcoin’s structural properties:
- Absolute scarcity: The 21 million unit cap is mathematically enforced and more rigid than gold’s supply constraints
- Verifiability: Supply is provable through transparent blockchain verification
- Divisibility: Superior to gold, divisible to 100 millionth units (satoshis)
- Portability: Billions in value transferable globally within minutes
- Durability: Digital permanence without physical degradation
- Censorship resistance: Decentralized network operation
Gold’s advantages:
- Historical precedent: Millennia of acceptance across civilizations
- Institutional trust: Central bank reserves, regulatory clarity, established legal frameworks
- Crisis performance: Stronger safe-haven behavior during acute market stress
- Liquidity depth: Approximately $300 billion daily turnover versus Bitcoin’s approximately $50 billion
C. Market Evidence and Performance Divergence
Recent market data reveals divergent performance during macroeconomic stress. Gold has demonstrated traditional safe-haven characteristics with significant appreciation during periods of geopolitical uncertainty, while Bitcoin has exhibited higher volatility and correlation with risk assets during acute stress periods.
This evidence suggests Bitcoin functions as a secondary hedge that stabilizes after initial risk-off conditions, whereas gold serves as the primary safe haven during market crises. The “digital gold” narrative remains contingent on continued regulatory clarity and market maturation.
However, long-term cumulative returns demonstrate Bitcoin’s asymmetric upside potential, with returns vastly exceeding gold over extended time horizons — albeit accompanied by extreme volatility that renders direct comparison with gold’s stability characteristics problematic.
D. Implications for Asset Classification
The intrinsic value debate carries practical implications for legal and tax treatment. The more sophisticated analytical framework recognizes gold and Bitcoin as complementary assets with different risk/return profiles and use cases rather than direct competitors:
- Gold: Superior for conservative wealth preservation, regulatory certainty, and crisis hedging
- Bitcoin: Superior for portability, divisibility, censorship resistance, and asymmetric upside potential
The $2+ trillion cryptocurrency market capitalization and growing institutional adoption suggest markets have rendered their verdict on the “no value” thesis, regardless of philosophical debates about intrinsic worth.
E. Critical Perspectives on Long-Term Viability
Notwithstanding the foregoing analysis, serious critical voices merit consideration. Gold’s civilizational durability as a store of value, measured in millennia across diverse cultures and economic systems, presents a stark contrast to Bitcoin’s fifteen-year existence. From this perspective, cryptocurrencies may yet prove to be a transient phenomenon of uncertain future rather than a permanent fixture of the global financial architecture.
Furthermore, the quantum computing timeline estimates, while representing expert consensus, carry inherent uncertainty. Scientific breakthroughs rarely adhere to predicted schedules, and futurological forecasts have historically proven unreliable. A miscalculation in this regard could render all cryptocurrencies valueless overnight—a systemic risk without parallel in traditional asset classes.
Additional doubts regarding cryptocurrency credibility arise from their anonymous and opaque genesis. The vast majority of global Bitcoin holdings are controlled by a small number of mysterious wallets that execute no transactions or only very rare ones. This concentration means the supply structure remains fundamentally opaque and does not reflect a spontaneous market mechanism, raising questions about potential manipulation and the true nature of Bitcoin’s decentralization claims.
VI. Quantum Computing and Cryptographic Security
A. The Nature of the Quantum Threat
Quantum computing represents a legitimate technical concern for blockchain security, though current evidence suggests the threat is manageable rather than existential within relevant planning horizons.
The cryptographic foundations of major cryptocurrencies rely on mathematical problems that classical computers cannot solve efficiently. Quantum computers, when sufficiently advanced, could theoretically compromise these foundations through two primary attack vectors:
Shor’s Algorithm (major threat): Could break Elliptic Curve Cryptography (ECC) used in Bitcoin and most cryptocurrencies, enabling derivation of private keys from publicly exposed public keys.
Grover’s Algorithm (minor threat): Could reduce SHA-256 security strength by half, though the remaining 128-bit security level remains formidable against practical attacks.
B. Timeline and Current Capabilities
Breaking Bitcoin’s ECDSA encryption would require millions to billions of stable, error-corrected qubits. Current quantum computers, including Google’s Willow chip (105 qubits, December 2024) and Microsoft’s Majorana chip (February 2025), remain far below this threshold.
Expert consensus estimates 10-20+ years before cryptographically relevant quantum computers (CRQC) capable of threatening current blockchain cryptography become operational. NIST recommends migration to post-quantum cryptography by 2035, while IBM’s roadmap projects several thousand qubits by 2033. This timeline provides a substantial preparation window for the industry. Analysis from BeInCrypto confirms quantum advances are not an immediate risk to Bitcoin security.
C. Vulnerability Assessment
Approximately $718 billion worth of Bitcoin is held in legacy addresses (Pay-to-Public-Key format) where public keys are already exposed on the blockchain, creating theoretical vulnerability to future quantum attacks. Modern address formats provide additional protection by keeping public keys unexposed until spending occurs. The Human Rights Foundation analysis provides comprehensive assessment of vulnerability timelines and mitigation strategies.
D. Post-Quantum Cryptography Solutions
The critical distinction often missed in quantum threat analyses is that blockchain technology is not inherently quantum-vulnerable — the cryptography is modular and upgradeable:
NIST Post-Quantum Standards: The National Institute of Standards and Technology released post-quantum cryptographic standards in August 2024, with plans to deprecate RSA-2048 and ECC-256 by 2030 and fully disallow them by 2035.
Protocol Upgrade Paths: Bitcoin and Ethereum developers are actively researching soft fork mechanisms to transition to quantum-safe cryptography.
Quantum-Resistant Implementations: Quantum random-number generators are already being implemented by banks, governments, and cloud providers.
Industry Preparation: The blockchain industry has identified the threat and is developing migration strategies, though implementation in live networks with substantial capitalization presents technical challenges.
The quantum threat represents a theoretical vulnerability requiring proactive preparation rather than an imminent crisis. Similar to how internet security protocols have evolved over decades, blockchain cryptography will likely adapt before quantum computers pose practical threats.
VII. Consensus Mechanisms and Transaction Validation
A. Proof-of-Work and Computational Competition
Proof-of-Work constitutes a consensus mechanism requiring network participants (miners) to solve computationally intensive cryptographic puzzles for block validation. The process involves finding a nonce value that, when combined with block data and hashed through a cryptographic function (SHA-256 for Bitcoin), produces a result meeting the difficulty criterion.
Key properties include high cryptographic security from cost asymmetry, economic resistance to 51% attacks given sufficient decentralization, and deterministic transaction finalization. However, significant energy consumption represents a fundamental architectural limitation — according to the Cambridge Bitcoin Electricity Consumption Index, the Bitcoin network consumes approximately 130-160 terawatt-hours annually (2025 estimates), comparable to medium-sized national economies.* The Cambridge Judge Business School methodology provides updated assessment approaches.
*Note: The Cambridge Bitcoin Electricity Consumption Index underwent methodology revision in 2023, which adjusted some historical estimates to improve accuracy.
B. Proof-of-Stake and Economic Network Security
Proof-of-Stake replaces computational competition with an economic staking mechanism, where validators are selected to create blocks proportionally to the quantity of staked tokens.
Ethereum’s transition from Proof-of-Work to Proof-of-Stake through “The Merge” upgrade on September 15, 2022 reduced network energy consumption by an estimated 99.95%, demonstrating practical feasibility of transformation in an operating network with capitalization exceeding hundreds of billions of dollars. Consensys reported elimination of 99.99% of carbon footprint, while New Scientist confirmed the dramatic energy reduction. The EU Blockchain Observatory Trend Report provides institutional analysis of this transition.
C. Alternative Consensus Architectures
Blockchain technology development drives consensus mechanism innovations seeking to optimize the blockchain trilemma — the theoretical difficulty of simultaneously achieving optimal decentralization, security, and scalability:
Delegated Proof-of-Stake (DPoS) implements a representative democracy model where token holders vote for a limited number of delegates responsible for block validation.
Practical Byzantine Fault Tolerance (pBFT) achieves finalization through multi-phase communication between nodes, tolerating up to one-third dishonest or faulty participants.
Proof-of-Authority (PoA) utilizes the reputation of pre-authorized validators, sacrificing decentralization for high performance in private or consortium blockchains.
VIII. Central Bank Digital Currencies
Central Bank Digital Currencies (CBDC) represent digital forms of national money issued and controlled by central banks as digital equivalents of cash or bank reserves. In fundamental distinction from cryptocurrencies, CBDCs maintain centralized regulatory control and trust architectures while potentially utilizing distributed ledger technology elements.
A. Development Motivations
According to the Bank for International Settlements, CBDC development motivations encompass:
- Financial inclusion for populations unserved by traditional banking,
- Payment system operational efficiency through reduced transaction costs,
- Strengthened monetary policy transmission through new implementation tools,
- Defense of monetary sovereignty against private cryptocurrencies and foreign CBDCs,
- Catalyzing financial innovation through platform creation.
B. Architectural Taxonomy
Retail CBDCs are designed for households and businesses as digital cash equivalents. Wholesale CBDCs serve interbank settlements and financial market operations.
Architectural approaches include the two-tier model where the central bank issues CBDC to financial intermediaries serving end users, and the direct model where the central bank maintains direct relationships with end users.
C. Global Implementation Status
According to BIS research, over 90% of surveyed central banks are actively conducting CBDC work. Operationally functioning retail CBDCs include Sand Dollar (Bahamas), DCash (Eastern Caribbean), eNaira (Nigeria), and JAM-DEX (Jamaica).
The most ambitious project remains China’s e-CNY (digital yuan), which in pilot phase has created hundreds of millions of digital wallets. The European Central Bank is conducting the preparation phase of the Digital Euro project.
IX. Regulatory Framework
A. European Union
The MiCA Regulation introduces comprehensive regulatory framework for crypto-assets in the EU, encompassing licensing requirements for service providers, stablecoin issuance rules, and consumer protection measures. ART and EMT provisions apply from 30 June 2024, with the general CASP regime applying from 30 December 2024. For current status updates, see Hogan Lovells MiCA analysis, CSSF Luxembourg guidance, and Bundesbank MiCA overview.
The DAC8 Directive, adopted October 17, 2023, extends automatic exchange of tax information to crypto-asset transactions, implementing the OECD Crypto-Asset Reporting Framework (CARF). Member States must transpose by December 31, 2025, with first reporting from January 1, 2026. For detailed implementation guidance, see Deloitte’s CARF analysis, EY Luxembourg transposition overview, and Sovereign Group’s CRS 2.0 and CARF explainer.
B. United States
The U.S. regulatory landscape remains fragmented across multiple agencies. The SEC asserts jurisdiction over crypto-assets qualifying as securities under the Howey test, while the CFTC claims authority over crypto-asset derivatives and commodities. The FinCEN applies Bank Secrecy Act requirements to virtual asset service providers.
C. International Standards
The Financial Action Task Force (FATF) has established international standards for virtual asset service providers, including the “travel rule” requiring transmission of originator and beneficiary information with transactions. TRM Labs provides updates on Recommendation 15 implementation across key jurisdictions.
The Basel Committee on Banking Supervision has adopted prudential standards for banks’ crypto-asset exposures, effective January 1, 2025, establishing capital requirements differentiated by asset classification. For detailed analysis, see Skadden’s assessment of bank capital standards, PWC Switzerland BIS prudential standards overview, and Ashurst’s final standard analysis.
X. Tax Treatment
A. General Principles
In most major OECD jurisdictions, cryptocurrencies are treated as property rather than currency for tax purposes, with dispositions triggering capital gains taxation. Key taxable events include:
- Sale of cryptocurrency for fiat currency,
- Exchange between cryptocurrencies,
- Use of cryptocurrency for goods or services,
- Receipt of cryptocurrency through mining, staking, or airdrops.
Treatment of staking rewards and airdrops differs substantially between jurisdictions regarding timing and characterization as ordinary income versus capital gains. Some countries provide exemptions for de minimis personal transactions or long-term holdings.
B. Reporting Obligations
The OECD CARF framework establishes standardized reporting requirements for crypto-asset service providers, with reporting obligations commencing January 2026 and first automatic exchanges expected in 2027, facilitating automatic exchange of information between tax authorities.
Taxpayers bear responsibility for maintaining transaction records, determining cost basis, and reporting gains and losses. The pseudonymous nature of cryptocurrency transactions creates particular compliance challenges, addressed through enhanced reporting requirements and chain analysis capabilities.
XI. Anti-Money Laundering Considerations
Cryptocurrencies present heightened money laundering risks due to pseudonymity, cross-border operability, and potential for rapid transfer. The FATF Recommendations require:
- Customer due diligence for virtual asset service providers,
- Transaction monitoring and suspicious activity reporting,
- Implementation of the travel rule for information sharing,
- Licensing or registration of service providers.
Privacy-enhancing cryptocurrencies (Monero, Zcash) and mixing services present particular challenges, with some jurisdictions imposing enhanced due diligence requirements or outright prohibitions.
XII. Conclusion
Cryptocurrencies represent a transformative innovation at the intersection of computer science, economics, and law, challenging established categories and requiring development of novel regulatory frameworks. The rapid evolution of the technology — from Bitcoin’s introduction in 2009 through the emergence of smart contract platforms, stablecoins, and decentralized finance — has consistently outpaced regulatory responses.
The debates surrounding intrinsic value and quantum computing threats, while intellectually significant, should not obscure the practical reality that cryptocurrencies have achieved substantial market capitalization, institutional adoption, and regulatory recognition. The question of “intrinsic value” applies equally to traditional monetary assets including gold, while quantum computing threats are manageable through cryptographic upgrades within available preparation timelines.
The European Union’s MiCA Regulation represents the most comprehensive attempt to establish a unified regulatory framework, balancing innovation promotion against financial stability and consumer protection concerns. The ongoing development of CBDCs by central banks worldwide signals recognition that digital currency innovation will reshape monetary systems regardless of regulatory stance toward private cryptocurrencies.
For legal practitioners and compliance professionals, cryptocurrency-related matters require interdisciplinary expertise spanning financial services regulation, tax law, anti-money laundering compliance, and technology law. The continued evolution of both technology and regulation ensures that this area will remain at the frontier of legal development for years to come.
The fundamental tension between the decentralized, borderless nature of cryptocurrency networks and the territorial basis of legal jurisdiction remains unresolved. International coordination through bodies such as the FATF, OECD, and Basel Committee represents progress toward consistent standards, yet substantial divergences in national approaches persist. The ultimate resolution of this tension — whether through technological adaptation, regulatory harmonization, or some combination — will determine the long-term trajectory of cryptocurrency integration into the global financial system.

Defending citizens’ freedom and property is a message that resonates regardless of political affiliation. One would be hard-pressed to find a more compelling narrative than that of a government threatening fundamental individual rights. The problem, however, is that in practice the president is defending the freedom of fraudsters to conduct operations that systematically destroy the assets of the very citizens he claims to protect—while undermining the stability of the financial system his veto was ostensibly meant to safeguard.

[2025-11-28] What’s most striking about the BitClub case, reading through the court documents and chat logs, is how ordinary the fraud seems. There’s no criminal genius on display, no sophisticated financial engineering. Goettsche and his colleagues simply promised returns they couldn’t deliver, fabricated evidence of operations they hadn’t conducted, and paid early investors with money from later ones. They made mistakes—keeping incriminating chat logs, using their real names, failing to cover their financial tracks adequately. They were caught not because investigators cracked some elaborate code but because they got greedy, sloppy, and inevitably, someone complained to the authorities.
Robert Nogacki: The End of Crypto’s Wild West
[2025-11-28] On October 10, 2017, a woman in a ball gown with Louboutin red-soled heels boarded a flight from Sofia to Athens and disappeared. Ruja Ignatova—the self-styled “Cryptoqueen”—had spent the previous three years building OneCoin, which she claimed would “kill Bitcoin.” She had addressed thousands of followers in packed arenas across Europe, promising them a piece of the cryptocurrency revolution. What she had actually built was an elaborate fiction: OneCoin had no blockchain, couldn’t be traded, and existed only as numbers in a closed system she controlled. When German authorities moved to arrest her, she vanished, leaving behind 3.5 million defrauded investors and losses exceeding four billion dollars. She remains on the F.B.I.’s Ten Most Wanted list, with a five-million-dollar reward for information leading to her capture.

Robert Nogacki: The Boundaries of Decentralization. Examining DeFi’s Regulatory Status Under MiCA and Its Implications for Cryptoasset Licensing Requirements
[2025-10-07] The emergence of decentralized finance (DeFi) has precipitated a fundamental reconsideration of regulatory boundaries in European cryptoasset markets. The Markets in Crypto-Assets Regulation (MiCA), which entered into force in 2023, explicitly excludes from its scope services provided in a “fully decentralized manner” without any intermediary. Yet this ostensibly straightforward exemption masks considerable complexity. The absence of precise definitional parameters for “full decentralization,” coupled with the inherent sophistication of DeFi ecosystems, generates substantial uncertainty regarding both the exemption’s actual scope and its practical implications for market participants operating within the cryptoasset space.

This wasn’t just another whale movement – it was the largest “Satoshi-era” transfer in Bitcoin’s history, involving coins that had been untouched for over 14 years.
Robert Nogacki: The Bitcoin Bubble: El Salvador’s Cautionary Tale
[2025-08-04] As financial regulators across the developed world cautiously navigate the murky waters of cryptocurrency regulation, one small nation decided to cannonball into the deep end. The results have been precisely what any rational economist would predict: a spectacular belly flop. El Salvador, a country better known for its stunning volcanic landscapes and rich indigenous heritage than its financial innovation, became the world’s first crypto laboratory in 2021. At the behest of Nayib Bukele – a man who unironically crowned himself “the world’s coolest dictator” – the nation embraced Bitcoin as legal tender with the fervent optimism of a college freshman discovering libertarianism. The government’s grand vision was intoxicatingly simple: transform a struggling economy plagued by poverty and crime into a gleaming crypto utopia. What could possibly go wrong when a nation with limited digital infrastructure pivots its economic future toward a notoriously volatile digital asset?
