Yep. But with that the difficulty is going through the roof and earnings are dropping. Ethereum had A LOT of hash power while ETC isn't really used by anyone so where are the earnings supposed to come from. It's not going to be economically viable because the electricity is a fixed cost, even if some individual miners are trying it out.

There is a new PoW fork that was started by miners that want to continue mining. Some of the work could go there assuming it doesn't tank. I personally don't see the utility though, doubt it will be able to attract many users.
