Bitcoin mining machines can produce a loud, fan-like noise. Board members said that if they fielded any noise complaints, Doeden would be responsible for sound-proofing the facility and asked that he have a plan in place.

But noise hasn't been an issue, said City Planner Eric Miller.

Originally, Doeden's business was limited to 70 machines. But things have gone smoothly and the board approved 80 more for a total of 150.
