https://www.ccn.com/chinas-bitmain-gets-approval-for-us-bitcoin-mining-operation/Bitmain, Chinese cryptocurrency mining company, has been given a green light to set up a blockchain facility in Western Walla Walla County, a county in the U.S. state of Washington. Local newspaper Union-Bulletin wrote that the decision was in complete agreement of the three commissioners involved in the situation.
Bitmain is opening overseas mining farms all over the place. My guess is that they believe China will ban mining in China and they are diversifying.
