Senator Cynthia Lummis has released a report criticizing the Biden administration's proposed 30% excise tax on the energy consumed by Bitcoin miners. In her report, Lummis argues that increasing taxes on Bitcoin miners could lead to the industry leaving the United States, resulting in a reduction in tax revenues. She points out that Bitcoin miners have been able to sell excess energy back to the grid during peak demand, acting as a Controllable Load Resource for the grid.
