Internet reports that according to Bitcoin Laws, U.S. Senator Cynthia Lummis resubmitted the Bitcoin bill to the Senate, after the previous 2024 version was shelved in the committee. The new version, like the previous version, proposes to purchase 1 million bitcoins over five years, but with several key differences. The 2025 version of the Bitcoin Act sets a stricter plan to purchase 200,000 bitcoins per year (rather than the "maximum" of 200,000 bitcoins in the 2024 version). The new version also strengthens hold requirements, removing exceptions from previous versions on repaying federal debt instruments. The bill adds a clause to coordinate Bitcoin purchases with the Exchange Rate Stability Fund (ESF), which is not mentioned in the 2024 version. ESF is a reserve fund of the U.S. Treasury Department with approximately $39 billion in assets that could be tapped by the administration's Bitcoin acquisition. In terms of gold revaluation, the new version clearly stipulates that the proceeds from revaluation of Federal Reserve gold should be used to purchase bitcoins, while the 2024 version only includes these funds in general funds, which is a major change.
