Ethereum classic maybe left in the dark for the time being as eth is the primary coin powering the blockchain applications at the moment. It looks like etc has a lack of development and support and a lot of people are against it due to the censorship. One can only dream about etc being huge in the future for now.
Yeah its kind of like btc and ltc. It will always remain I think and have a few small projects based on it but overall its always going to be the younger brother to eth.
