Q4 Hashrate Analysis: U.S. and China Lead Global Bitcoin Mining Expansion Toward Zettahash Era

Bitcoin’s computational power has demonstrated remarkable growth throughout early 2025, accelerating from 801 exahash per second (EH/s) at the beginning of January to an unprecedented 1,100 EH/s in recent measurements. This substantial 37% increase underscores the network’s continued security enhancement and mining sector expansion. Industry analytics reveal that three nations dominate this computational surge, with the United States and China demonstrating particularly significant exahash contributions. Both countries have substantially increased their mining infrastructure and operational capacity, positioning themselves as primary drivers behind Bitcoin’s progress toward zettahash-level processing capabilities. Russia maintains its position as another major contributor to the global hashrate distribution, though its growth trajectory appears more moderate compared to the leading two nations. The coordinated expansion across these key jurisdictions highlights the increasingly diversified geographical distribution of Bitcoin mining operations following previous industry migrations. This geographical diversification strengthens network resilience while supporting continued hashrate growth. Market observers note that this accelerated expansion coincides with improved mining hardware efficiency and strategic energy procurement arrangements in major mining regions. The sustained investment in computational infrastructure suggests continued confidence in Bitcoin’s long-term security model and economic viability among institutional mining operations.
