Cambridge research shows that China’s Bitcoin mining power fell by 40% before the crackdown, while the United States’ hash power has quadrupled.
China’s crackdown on Bitcoin (BTC) mining due to energy consumption concerns is widely regarded as the trigger for the miners’ exodus from Asia to Western countries. But new research by the Cambridge Centre for Alternative Finance suggests that the shift in mining power started before China’s renewed scrutiny.
Reuters reported that China’s total computing power connected to the Bitcoin network, or hash rate, fell from 75.5% in September 2019 to 46% in April 2021, before the Asian country even officially announced the mining crackdown.
During the same 18-month period, the United States quadrupled its share of the global Bitcoin hash rate from 4% to 16.8% to become the second-largest producer of Bitcoin. Another country often named a potential destination for miners’ relocation, Kazakhstan, increased its share to 8% and became a primary Bitcoin producer.
