Greg Gianforte, the Governor of Montana, has signed into law a bill largely preventing local governments in the state from passing laws prohibiting cryptocurrency mining.

According to records with the Montana legislature, Gianforte signed SB178 into law on May 2 after the bill had passed both the state House and Senate. The legislation effectively enshrines crypto miners’ rights in the U.S. state by revising existing laws, prohibiting discriminatory electrical rates for mining firms, and not allowing taxation for crypto used as a method of payment.
