Honestly, I see it on 10$ in few weeks, maybe even in few days. I would love to be wrong, since if BTG remain over 100$ , it would attract some GPU miners which now mine zCash and Ethereum, so difficulty would decrease on those two, but IMHO BTG is not worth more than 10$. I wouldn't pay even 10$ for it. And everything because of greedy developers with their pre-mine "get rich quickly scheme"
