How can i exchange for USD???

My rig is mining ETH right now but I'm about to switch to RVN and might buy some 4GB cards to mine it. My only issue is the only thing I have is Exodus and Coinbase and coinbase doesn't support raven so I'm not sure how to cash out my RVN for USD (to pay for and re-invest in the rig). I was going to send it to Exodus then swap it for ETH, once I get it in ETH i can cash it out on Coinbase but Exodus doesn't support swapping RVN. How do you guys cash out?
