The regulation of cryptocurrencies (#CryptoRegulation) is a crucial topic today, given the exponential growth of digital assets and their impact on global financial systems. Governments seek to balance technological innovation with consumer protection, the prevention of money laundering, and economic stability. While countries like the U.S. and the EU are advancing towards stricter regulatory frameworks —such as MiCA in Europe— others adopt more flexible or even restrictive positions. This disparity creates legal uncertainty and limits international interoperability. Clear and coherent regulation is essential to foster investor confidence, enable the development of legitimate projects, and curb the illicit use of crypto assets. However, overregulation that stifles innovation must be avoided. The challenge lies in designing rules that recognize the particularities of the blockchain ecosystem, without losing sight of the fundamental principles of financial law and the protection of the public interest.
