I have to chose one among ETH and ETC and the way i did it is to withdraw everything to bitcoin and then buy ETC after its drop. If you hold ETH for months as well, you may wanna do this too. Its going to help you win over this fight.
The ETC price is dropping at the moment, so you have to be careful. Maybe the pump of ETC has finished.
It is difficult to predict. Some of the ETC pumpers are quite rich, so they might have enough money to support the price.
