Fort Worth is the first city in the U.S. to mine bitcoin, and will run mining rigs out of city hall

Fort Worth, Texas, is now the first city government in the United States to mine bitcoin — and in an almost poetic devotion to the initiative, Mayor Mattie Parker oversaw the construction of a small mining farm in City Hall.

Three Bitmain Antminer S9 mining rigs will run 24 hours a day, seven days a week, in the climate-controlled information technology wing of Fort Worth City Hall. The city says the miners will be hosted on a private network to minimize the security risk.
