ETC is the original Ethereum chain. So yes, the premines/ICO in the ETH chain also exists in the ETC chain. ETC. however, no longer has Vitalik developing it - so that should be a plus for you.
I hold a few myself and I am really interested in ETC.
There is something that bothers me though - ETC being a fork of ETH has the same huge amount of premined coins? If this is true, I am not sure it will end well, I don't trust Vitalik.
