Foundry USA Cuts Bitcoin Mining Power in Response to Winter Storm Fern

The statement is strongly supported by a consistent body of evidence from multiple primary sources. Five of the provided sources, including one from a high-authority publication (Cointelegraph), directly and explicitly corroborate the core claims. They consistently report that Foundry USA, a major Bitcoin mining pool, experienced a hashrate drop of approximately 60%. These sources unanimously attribute this reduction to power curtailments made in response to Winter Storm Fern. One source provides a direct quote describing the event as a "textbook example of demand response," which reinforces that the power reduction was a deliberate action to support the energy grid during the storm, rather than an accidental outage. The remaining sources, while having low relevance to this specific event as they do not mention Foundry USA or Winter Storm Fern, discuss the general and established practice of Bitcoin miners voluntarily reducing power during extreme weather to stabilize the grid. This contextual information aligns with the events described in the more relevant sources. There are no contradictions in the evidence provided. The consistency, specificity, and high relevance of the primary sources make the statement very likely to be true.
