New Hampshire Senate Stalls Crypto Mining Deregulation Bill After Split Vote

Concord, NH – A bill aimed at significantly deregulating cryptocurrency mining in New Hampshire has stalled in the State Senate after a split vote. The legislation, known as HB 639, seeks to shield cryptocurrency miners from local regulations, potentially impacting noise limits, electricity rates, and other operational aspects.

The bill's primary objective is to promote the cryptocurrency industry within the state by preventing local authorities from imposing restrictions that could hinder mining operations. Representative Keith Ammon, a Republican from New Boston, introduced the bill, expressing his desire to bolster the crypto sector in New Hampshire. Ammon has publicly dismissed environmental concerns related to cryptocurrency mining's impact on the planet and electrical grids.

If enacted, HB 639 would have prevented state agencies and local officials from setting sound limits on cryptocurrency mining, even while miners would still need to comply with other sound ordinances. It also sought to prohibit charging cryptocurrency miners additional fees for their impact on the power grid and prevent restrictions on using cryptocurrencies for buying or selling items.

The bill received approval in the House of Representatives in April of this year. However, it faced strong opposition in the Senate, particularly concerning its potential environmental impact and the importance of local control.

The Senate Commerce Committee deliberated on the bill on October 30, ultimately resulting in a 3-3 deadlock. This split vote effectively stalled the bill, preventing it from moving forward in its current form. The full Senate is expected to reconsider the legislation in the new year.

Environmental groups have actively lobbied against the bill, emphasizing the significant energy consumption and water usage associated with cryptocurrency mining. They argue that shielding miners from regulations could lead to increased environmental strain and reduced local control. Catherine Corkery, the New Hampshire chapter director for the Sierra Club, expressed confidence that they have the necessary votes to defeat the bill on the Senate floor, highlighting the importance of local control to libertarian-leaning Republicans.

Supporters of the bill, including libertarians and cryptocurrency advocates, argue that deregulation would attract investment and innovation to New Hampshire. They believe that fostering a welcoming environment for cryptocurrency mining could create new economic opportunities and position the state as a leader in the blockchain industry.

The debate surrounding HB 639 reflects a broader discussion about the appropriate level of regulation for the rapidly evolving cryptocurrency sector. While some advocate for minimal intervention to encourage growth, others emphasize the need for safeguards to protect the environment and local communities.

Notably, in May 2025, New Hampshire became the first state to approve a crypto reserve law, allowing the state treasurer to invest up to 5% of public funds in assets like Bitcoin. This move signaled a forward-thinking approach to digital assets, but also highlighted the ongoing debate about how to best regulate and integrate cryptocurrencies into the state's economy.

The future of HB 639 remains uncertain as it awaits reconsideration by the full Senate. The outcome of this vote could significantly impact the development of the cryptocurrency mining industry in New Hampshire and set a precedent for other states grappling with similar regulatory challenges.
