According to Blockworks, Brazilian Congressman Eros Biondini proposed establishing a Bitcoin sovereign strategic reserve, ResBit, planning for Bitcoin to comprise 5% of the national reserves.
U.S. Senator Cynthia Lummis plans to reintroduce a bill to establish a Bitcoin reserve, proposing that the Treasury purchase 1 million Bitcoins over five years and hold them for at least 20 years.
