I do not think ETC is a very good coin, of course it can still bring some profit in a short time, but I find that it is not suitable for long-term investment. Better ETH.
I think you have to do a little more study about the potential of ethereum classic, it is up to you if you won't get involved in etc for long term investment. But I suggest to you that don't focus on one coin, you must split your money in different altcoins, and now I would say that this is a chance to buy in a cheap price.
