Michael S. Barr has stepped down as Vice Chair for Supervision at the Federal Reserve. His strict approach to crypto regulation has been well-documented. Now, his resignation could bring about significant changes in the U.S. cryptocurrency regulatory environment. This comes at a particularly uncertain time as the Federal Reserve enters what is considered a 'lame-duck' period. This could mean new opportunities or directions for Bitcoin regulation in the near future, as successors may adopt different views and policies.
