Mining Power Concentration Threatens Bitcoin Decentralization

Bitcoin's decentralization is facing a significant challenge due to mining power being concentrated in just three countries: the United States, China, and Russia. According to data, these nations account for approximately 68% of the network's total hashpower.

The imbalance has raised questions about the practical limits of decentralization in Bitcoin, which was built to resist geographic control. Analyst Lucky pointed out that while the network is technically permissionless, real-world factors have pushed mining capacity into a handful of jurisdictions.

The U.S. leads due to institutional-scale operations, access to capital markets, and relatively clear regulations in states like Texas. China continues to contribute despite official bans, with underground and relocated operations drawing on cheap hydropower and coal. Russia benefits from low electricity costs and cold climates that reduce cooling expenses.

This concentration of mining power is driven by infrastructure, energy access, and regulatory dynamics rather than coincidence. As Lucky argued, tracking hashpower distribution offers a more honest view of where influence within the BTC network actually sits.
