Shift has not done any marketing until now.
It is only available on Livecoin and Bittrex and as we all know, Livecoin has very low volume for everything.
Bittrex is not taking any new registrations, so it is not helping Shift.
New exchanges will come, everything just takes time !
Theres enough volume on bittrex though already. As you can see shift is gaining momentum and flying past the 10$ mark
