Have you guys checked this thread out https://bitcointalk.org/index.php?topic=446640.0. Its a new altcoin to USD exchange. Maybe the Devs could look into this and get a digibyte to USD trade pair on there. To be honest I do not know how legit they are, but it can be something worth looking into for a USD exchange until Digibyte devs sorts out or release their very own USD exchange.
