The Digital Asset Act $BTC is an important regulatory framework for countries to respond to the rapid development of the cryptocurrency market, aiming to balance innovation and risk prevention. Its core typically includes clarifying the legal attributes of digital assets, establishing a market entry system for trading platforms, investor protection mechanisms, and anti-money laundering rules. Some acts categorize cryptocurrencies into different types such as securities and payment tokens for differentiated regulation, like the EU MiCA Act, which emphasizes trading transparency and operator responsibility. By establishing a licensing system and information disclosure requirements, it not only regulates market order but also provides a development pathway for compliant enterprises. However, the speed of technological iteration and cross-border regulatory coordination remain challenges, needing to reserve space for blockchain technology innovation while preventing financial risks.
