ETC to EtH is Like LTC to BTC
I think ETH is the future with much feature, being actively maintained, developed and used and will soon take the crown from BTC.
ETC is good for speculation trading with technical analysis.
and people who bought this for 3-4$ are rich now just like LTC

You can Hold this sooner or later it will be Profitable because of the whole cryptocurrency space booming.
But remember it will never surpass ETH
