According to Techub News, according to Bitcoin.com, former NSA employee Snowden said at the "Bitcoin 2024" conference that Bitcoin transactions are not anonymous and can be traced back to individuals, which poses a risk to personal privacy. Although people generally "misunderstand" that Bitcoin transfers provide complete anonymity, most transactions can be linked through various upstream and downstream channels, such as trading platforms that meet regulatory requirements. This connection can track transaction history, thereby revealing sensitive information such as user life and affiliations.
