Yes, ETC's price is pumped up a lot! Nothing will guarantee that it will keep moving up. We should have noticed that the lowest price went to 0.0001BTC! It will possibly crash to that level at any time in term of investment. Unless you have faith in ETC, buy it for the potential!
Any investment in ETC is speculative at best, at the moment. This thing is so in flux now, that even if you care about the coin, the uncertainty makes the risk completely over the too. I'm holding a few ETC at the moment (less than ten), and it's purely a gamble. I may be better off simply flipping a coin. But I have a hunch I intended to follow.
