Given the anonymity and decentralized nature of cryptocurrencies, it poses significant challenges in tracking and regulating transactions. Will the Treasury take a more proactive stance in developing new regulatory frameworks or collaborate with private sector entities to develop solutions? Are there any specific measures or technologies being considered to combat crypto-mixing practices that aim to obfuscate the origin and destination of funds? Additionally, how will the Treasury ensure that these efforts do not infringe upon the privacy rights of legitimate crypto users?
