It's very difficult for ETC to stand on even just for $50. Probably i think, middle 2018 there will be a change. As yet few online services or gambling sites that use ETC. ETC enthusiasts are less crowded, still less competitive with newly emerging altcoins.
ETC had almost low fluctuation in the market, I think it's hard for they to compete with the other altcoins. In addition ethereum was almost same interest like ETC that's why raising up of ETC to the market was affected too much.
