if ARK should go above 100$ then market cap should increase to 10.500.000.000 that's currently above 3 position (BCH).
I think it could go around 10 positions so let's say 1.000.000.000 by end of year, that's like 3x from 3.7$...I would say its gonna be around 11$ maybe higher if market wakes up.
but year 2018 is definitely gonna be interesting..and not just for ARK
