US Bitcoin Miners' Hashrate Reaches 30% – What's Next for Decentralization?

• American miners have reached a new record, controlling 30% of the Bitcoin hashrate.
• Their increased share could change the dynamics of the Bitcoin network.
• This growing dominance could have an impact on Bitcoin's decentralization.

For the first time in history, Bitcoin miners listed on US exchanges now control a record 30% of the Bitcoin network’s hashrate. This is an 800 basis point increase since the halving, highlighting the need for miners to strengthen their position in the Bitcoin ecosystem. This rapid dominance in the hashrate could have a significant impact on Bitcoin’s functioning and performance, which will inevitably impact altcoins. As US miners increase their share, they could attract attention due to a possible trend towards concentrated mining power, which is shaping the long-term outlook.

🚨 American Bitcoin Miners Reach Record 30% Hashrate Control! 🇺🇸

Following the halving, 14 publicly registered miners increased their stake by 800 basis points, marking a historically high level of dominance in the Bitcoin network.

US Miners' Share of Bitcoin Hashrate Is Growing

A graph showing the share of US-based miners in the network hashrate shows that there has been a significant increase in control over the Bitcoin network. In January 2022, they accounted for only 14.8% of the total US miner network hashrate. However, since December 2022, this number has increased to 24.4%, indicating a rapid strengthening of the US miners’ position in the mining field. By March 2025, this figure even reached an impressive 30%. This trend indicates that US miners control almost a third of the Bitcoin network, an all-time high.

The faster rise in US miners’ position can actually be traced back to the Bitcoin halving that occurred in May 2020, which led to strategic moves by publicly traded mining companies. Many of these initiatives were implemented throughout 2023 and early 2024. One such period was between November 2023 and February 2024, which saw an increase from 22.6% to 27.3%, confirming the aggressive approach of publicly traded miners to control the mining space. By mid-2024, this figure is projected to be in a sustainable range of 21% to 27%.

Impact on Bitcoin Decentralization

Decentralization is one of Bitcoin’s core characteristics. However, it is currently under threat due to the growing concentration of the network’s hashrate under the control of US-based miners. While increasing the share of the hashrate for US-based miners has increased Bitcoin’s security, it also runs counter to the ideal of a fully decentralized network. If these miners continue to increase their influence, it could lead to more centralized control, giving a few large players unlimited power over Bitcoin’s fate.
