Fézer, TamásAbramidze, Elene2025-01-062025-01-062024-06-05https://hdl.handle.net/2437/384306This thesis explores the regulatory frameworks governing cryptocurrencies in the European Union (EU), MS country – Finland, the United States, and specifically California, and crypto-friendly country – Switzerland and examines their impact on cross-border transactions. The author discusses about cryptocurrencies, digital and virtual currencies that use cryptography for security and operate on decentralized networks based on blockchain technology. They transform the way business transactions are carried out by enabling peer-to-peer transactions without the need for intermediaries. The realistic prospects of cryptocurrency replacing paper money in the future are under consideration. As cryptocurrencies are still relatively new, rapidly growing, and not yet subject to widespread legal regulation, they present a dangerous environment for both individuals and corporations. The legal frameworks of cryptocurrencies in the EU, where the evolving regulatory landscape seeks to balance innovation with consumer protection and financial stability, will be explored. In the US, the regulatory environment is fragmented, with various federal and state agencies asserting jurisdiction, leading to a complex compliance landscape. Switzerland's crypto-friendly policies and the establishment of the "Crypto Valley" in Zug position it as a leading hub for blockchain innovation. California's progressive strategy seeks to promote innovation while maintaining strict regulatory control, while Finland's approach is concentrated on consumer protection and anti-money laundering (AML) measures. This comparative analysis delves into the effectiveness of these regulations in fostering innovation, protecting consumers, and preventing illegal activities. It also examines the role of cryptocurrencies in facilitating cross-border transactions, highlighting their potential to streamline processes, reduce costs, and enhance financial inclusion. Through a comprehensive review of regulatory approaches and their implications for businesses and consumers, the purpose of this thesis is to bring clarity on how cryptocurrency regulation will develop going forward and how important it is to the world's business system.62enCryptocurrencyVirtual currencyBitcoinBlockchainDecentralized systemInternational TradeLawHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
