The Iron Rail Diner is the only business in the area that is now accepting a cryptocurrency known as a Dogecoin. The restaurant has been accepting Dogecoin since April 4, and it was not long before the word went viral and several cryptocurrency miners traveled to Mount Savage to spend their hard-earned Dogecoins, according to Iron Rail co-owner Terry Linn II. Linn thought locals might be attracted to the idea of Dogecoin, since it’s a sponsor of NASCAR.
