In 2013, the U.S Treasury Department officially declared that exchanges and traders of digital currencies like Bitcoin are regarded as "money service businesses" and are subject to official regulations. Neurologist and gun-rights advocate Peter Steinmetz was charged by a grand jury for operating an unlicensed bitcoin exchange.
Steinmetz and Bitcoin
This isn't the first time that the brain scientist has appeared in the national news. In 2014, he was arrested while carrying a rifle at Phoenix International Airport during a gun-rights demonstration. Steinmetz was also featured in an article from the Arizona Republic, for an anonymous Bitcoin donation worth $10,000 to the Barrow Neurological Foundation which was used in order to fund Steinmetz' brain research project.
