As of 2025, U.S. cryptocurrency legislation is gradually becoming clearer. Congress is advancing the Financial Innovation and Technology for the 21st Century Act (FIT21), which aims to establish a unified regulatory framework for crypto assets. This legislation clearly places the regulation of most crypto assets under the Commodity Futures Trading Commission (CFTC), while the Securities and Exchange Commission (SEC) focuses on security tokens. In addition, the U.S. Treasury is enhancing regulation of stablecoins and anti-money laundering, pushing for exchanges to comply with KYC. The overall trend indicates that the U.S. is striving to balance investor protection with promoting innovation, providing a clearer legal environment for the digital asset market.
