Great idea! We will consider it! May you send links to the best examples of trading competition?
I always welcome new exchange, it's better for us isersu, and how knows, maybe xebr will become leader one day.
I have a question though :have you considered making trading competition, as a way to attract new users?
You should check out Altcoin fantasy, they have a lot of trading competitions that you can see and maybe use for the exchange.
