The main theme of crypto in 2021 was China’s aggressive policytowards mining which resulted in a total ban of such activities being carried out by September.

Many of them moved to the United States — the world’s new mining mecca — while some left to Scandinavia and others to nearby Kazakhstan, with its cheap electricity.
