Only two exchanges? I do not know much about these exchanges, are they reliable? I can see the trading volume is not so much, why?
I wasn't familiar with either of them but I've used both for Oxy and not had problems.
Oxy is early in its dev cycle, volume will pick up when the app is released and marketing ramps up. They are also trying to get on other exchanges, but as you know exchanges are overwhelmed by new customers and coins and taking their time.
