It's very difficult for ETC to stand on even just for $50. Probably i think, middle 2018 there will be a change. As yet few online services or gambling sites that use ETC. ETC enthusiasts are less crowded, still less competitive with newly emerging altcoins.
All this can change overnight, and fact that this is original not copy is something that we must present in every talk about ETC and ETH. This one should be 10x upper instead of ETH.
I think that some things will be changed in 2018, and one of the first will be returning to basic principles of crypto currencies- decentralization.
It has some potential, but it's not widely implemented.
If it will get implemented more, ETC's price will rise.
It is better and cheaper than ETH at least, and represent real decentralized solution and as such is perfect starting point.
At least not soon. We will see a lot changes in the market, before classic will rise till 100$. To be honest I don`t see much sense in the ETC.
Actually there is more sense in ETC than in ETH existence, anyway there are many people who will hold this for a long time including me.
