I thought RPX was supported by binance that was one of my big reason to invest. I hope this will get listed in there soon.
This has been talked about here, and it's been brought up more than enough times in slack. For whatever reason, RPX's initial relationship with Binance fell apart. It seems like a relationship that can be fixed, but last time I check (and someone correct me if I'm wrong), fixing whatever issues with Binance wasn't a high priority for the team.
