The GIO ticker is already taken ...
We are aware of Graviocoin existence

But for GOLD.IO the GIO idea was born long before we started the thread, and we are the only EOS-based project with this ticker.
You are not going to list this in other exchanges other than EOS-related exchanges?
Also, if you are planning to be listed this coin in CMC, this graviocoin already took the ticker GIO.
Any problem that you think might arise in your future listings?
