I think it will dwarf the volume on bittrex soon.
Don't know. There is place to grow in each market. Ultimately, AUR will flow to iceland, but way to go. In the next months, there will be some challenges, and already great solutions being discussed. One of these challenges is how to get AUR back to iceland ? There is already a lot of AUR in iceland, but we dont know yet how many will actually hit the market. So foreign aur will somewhat need to be ''imported''.
From then, i guess ISX will drain Bittrex action / lets work toward this !
