According to Blockspace, currently seven states in the United States have proposed legislation related to "strategic Bitcoin reserves," with varying content and implementation methods. Oklahoma and New Hampshire allow investment in digital assets with a market value exceeding 500 billion USD (essentially covering only Bitcoin); Wyoming's legislation permits the use of state funds to purchase Bitcoin, but limits it to 3% of the total fund amount; Texas has two proposals, one allowing 1% of the state budget surplus to be invested in Bitcoin, and another permitting only Bitcoin donations; Pennsylvania and Ohio have also proposed allowing state funds to invest directly in Bitcoin, but the specific terms are limited. Additionally, North Dakota has only passed a resolution supporting digital asset investments, without forming a formal bill.
