Deep Tide Techflow News, on December 28, Brazilian Congressman Julia Zanatta warned that as the country advances the implementation of the Central Bank Digital Currency (CBDC) "drex", physical cash may face the risk of disappearing. She opposes a bill that aims to gradually phase out cash by 2025, arguing that the use of drex should remain voluntary to protect economic freedom. Zanatta emphasized several risks: social control, loss of privacy, and potential financial issues for those unfamiliar with technology.

Zanatta also called for increased public awareness and suggested a referendum to decide the future of drex, stressing that such a significant change should involve citizen participation in decision-making. Currently, the drex pilot program is facing delays due to privacy concerns.
