Where to purchase Origin Trail tokens for USD

Hi, I’ve been trying to find a way to get ahold of some Origin Trail (TRAC) tokens with USD for a bit, but haven’t had any success in finding a way to do that. The only way that I’ve seen to acquire TRAC tokens thus far has to exchange ETH for TRAC tokens. Is there any way to acquire TRAC without first converting fiat to ETH or BTC?
