Sorry but ETC will be continuing to go down for the time being. How long and how low is the question and it is not looking good because the hash power is also going down. No miner is willing to support the network for free and they are leaving slowly one by one.
This will not look good for those who fight for blockchain immutability and true decentralization.
Uhm... I am not aware that ETC miners did not get anything out of mining ETC. Why is that so?
