After China unbanned crypto mining, after previously wanting to eliminate the industry all together, it’s now prospering.
Xi Jinping announced his desire to lead in “clockchain” last year, so this plays right into that. But, there’s growth elsewhere, like your article mentions.
Among these regions we find the major mining centres of: Washington and New York States in the United States; British Columbia, Alberta, Newfoundland & Labrador, and Quebec Provinces of Canada; Iceland; Northern Scandinavia (Norway and Sweden); The Caucasus (Georgia and Armenia); the Siberian Federal District of Russia; Yunnan – and most importantly of all regions, Sichuan – provinces of China. There are also minor mining centres found in similar geographies such as Austria, Montana in the United States, and Guizhou Province in China. The remaining major mining regions which do not fit into the above geographical mould are Iran, Kazakhstan, and Xinjiang and Inner Mongolia provinces of China. Minor mining regions where the above described geography does not (or where we cannot be certain that it does) fit the above description include: Florida, Texas and Arizona in the United States; Western Australia and New South Wales states of Australia; Belgium; Belarus; the North West Federal District of Russia; Argentina; and Venezuela. See map for list of sources.
