Bitcoin's mining difficulty has adjusted upward to a new all-time high of 120 trillion, reflecting an unprecedented surge in global hashrate. The increase comes as next-generation ASIC miners from Bitmain and MicroBT deliver significant efficiency gains, making mining profitable even during periods of moderate price action.
North America now accounts for approximately 40% of global Bitcoin hashrate, with major facilities in Texas, Wyoming, and Quebec leading production. Several publicly traded mining companies reported record quarterly revenues driven by both higher Bitcoin prices and improved operational efficiency.
Environmental advocates note that an increasing share of mining operations are powered by renewable energy, with industry estimates suggesting over 55% of global hashrate now comes from sustainable sources.
