Bitcoin hashrate briefly drops to mid-2025 levels amid US winter storm

Bitcoin mining data platform Hashrate Index estimates the United States contributes the largest amount of the world’s mining power, with nearly 38% of the global hashrate.

Bitcoin network hashrate hit a seven-month low over the weekend as a massive winter storm bombarded the United States with snow and ice, pushing miners to curtail operations to stabilize the energy grid.
