About $300,000 worth of cryptocurrency mining servers were stolen from gubernatorial candidate Michael Williams’ office in Gainesville either late Tuesday night, May 8, or early Wednesday, May 9, according to campaign spokesman Seth Weathers.

Williams, a Republican state senator from Cumming, owns LPW Investments, a business with a server farm, at 2365 Monroe Drive in Gainesville, Weathers said. Weathers said the campaign has been using additional space in the building, although the servers were not kept in the campaign’s side of the building.

The servers process transactions for a service fee, Weathers said.

Examples of cryptocurrency include Bitcoin, a decentralized digital currency that’s not bound or regulated by any bank. Cryptocurrencies can be exchanged online for cash. A growing number of services and products as common as fuel from a gas station can be bought using cryptocurrencies.

Weathers said campaign operations have resumed in the building.

Williams had no comment on the incident when reached by the Forsyth County News, The Times’ sister paper.

The Hall County Sheriff’s Office requested assistance from the Georgia Bureau of Investigation on Wednesday. The investigation is ongoing, according to the GBI.
