[opinion and not financial advice]
We have just seen and probably in the middle of a strong run-up for LiteCoin [at USD72 at time of writing]. Lite coin is a companion coin for Bitcoin.
The relationship between ETC and older, bigger brother ETH is a little more edgy but, nonetheless, synergistic.
LTC is undervalued and so is ETC and in this piece I want to make the case of why ETC to ETC could be as high as 0.25 : 1 in the medium term (next 12 months) and that there could actually be a reversal. That is, ETC could overtake ETH as the platform coin.
Vitalik is a key architect, thought leader, and hype engine for Ethereum; a focus point and the weak point. Vitalik's Russian origin and his network in Russia will strengthen Ethereum in Russia and ironically it will strengthen the raison d'être for Ethereum Classic.
ETC has the best of both worlds, the technological impetus derived from Ethereum and ETH' leadership by Buterin, as well as the independence from the centralised weak point that is, one and the same, Vitalik Buterin.

At current prices ETC is undervalued and in the medium term should be more at the level LTC is now: $70-$80.
Equally, for ETH the existence of ETC is actually a good thing, as it, for the same reasons I have already mentioned, mitigates the risk.
If one accepts the merits of the lines of argument I have spelled out, then this should inform and guide the both the technical roadmap of the two platforms, as well as the architecting and positioning of the applications and ecosystem(s) built up them.

UPDATE: Since I wrote this 24 hrs ago the price of ETC to ETH has risen about 25%
