I agree that Ethereum Classic will be a big one for miners and also investors. There is a hard fork in March which is really important. Moreover ETC price did not pump for some reason in the past month. I believe February will be great for Ethereum Classic. We may see a decrease just after the fork but later will be fine also.
I also think that 2018 will be the year of Smart Contracts and specially for Ethereum. If Ethereum increases in price, people will be interested in ETC also which will make the price go higher.
I totally agree with your decision.
take this as a short profit, or even long-term benefit if you do feel better to participate to the ETC.
I am less so understanding about mining, because I am just a trader trying to analyze the price development of a coin for the future.
I hope the ETC can provide a very satisfying advantage for those of us who participate in it
