42.5% of Bitcoin's computing power is concentrated in the United States, and the dispute over control of mining pools continues

Currently, approximately 42.5% of global Bitcoin computing power is concentrated in the United States, with US listed mining companies accounting for approximately 31.5% of global computing power. The Foundry USA mining pool holds the largest share in the world, with the top mining pools controlling over two-thirds of the computing power. Miners can freely switch mining pools, and devices have cross-border migration capabilities. The Stratum V2 protocol can reduce the control of mining pools over transaction options.
