Experts in global crypto policy express skepticism about the BRICS UNIT's ability to challenge the U.S. dollar's dominance. Despite efforts to reduce reliance on the dollar, significant obstacles remain, including political differences among BRICS nations and the dollar's 57.3% share in global reserves. India and Brazil have shown reduced enthusiasm for a common currency, and the 2025 summit confirmed no immediate plans for a joint currency. Additionally, U.S. President Donald Trump has warned of potential tariffs against BRICS supporters, further complicating the initiative.
