This interactive map was created as part of the CBECI project, which is used to monitor cryptocurrencies and blockchain by a research team at the Cambridge Centre for Alternative Finance, University of Cambridge, Judge Business School.
This tool monitors countries and visualizes the geographical distribution of global Bitcoin hashrate. Calculations of the average share of hashrates by country are available in monthly interval time frames, and the first figure is displayed from September 2019. Here you will also find a second map that is exclusively focused on the distribution of hashrates in China by province.
According to this map, BTC mining is sovereignly controlled by China with 65.08%, followed by the USA with 7.24% and Russia with 6.90%. However, it is also interesting to see, that are here countries like such as Kazakhstan with 6.17%, Malaysisa with 4.33% and even Iran with 3.82%.

How does the map work?
“The map is based on geo-location data (i.e. IP addresses) of hashers connecting to the Bitcoin mining pools BTC.com, Poolin, and ViaBTC, who have kindly agreed to share aggregate-level data for research purposes. These pools collectively represent approximately 37% of Bitcoin total hashrate over the examined period. Figures are presented in aggregate to obfuscate pool-specific information”
