The United States currently accounts for 40% of global Bitcoin mining, but the upcoming halving event in April may push some miners offshore. The halving will cut mining rewards from 6.25 BTC to 3.125 BTC, impacting operations worldwide. U.S. miners are focusing on energy efficiency and low electricity costs to remain profitable. Despite potential short-term declines, experts predict that Bitcoin's global hash rate will continue to increase post-halving, with Bitdeer alone planning over one gigawatt of new facilities in the next 24 months.
