do you plan to go on coinbase? it would be the best thing of the world for dash! we will go to the moon in some minutes
GDAX and Coinbase are definetely exchanges where Dash wants to be included as they handle rather large volumes.
Unfortunetely Coinbase is pretty closed with regards to releasing official information about pairs they are either consider implementing
or in the process of implementing already.
It will pretty much be a game of wait and see.
