Ethereum classic hashrate is already full of asics with less than 5 gigabytes of memory. When other ASICs with more memory come here after the end of Ethereum mining, there will be no profit for video cards. The price of ETHW futures has already fallen over 50%, and when the exchanges open coin transfers, everything will end up with a big drop.
I'm following the hashrate of both coins and it's clear about the 5gb Asics changing to ETC, and there are another miners changing to ETC to delay the bomb in ETH (I don't know how many)
About ETHW we can't say anything yet because it's only futures right now, once the fork happens, people will probably dump a lot, it will be free money for some, but in the long run, maybe will hold some value.
I'm anxious to have these answers about the future of mining, somehow I think we'll have a balance
People are not considering a strong POW coin arising, and the next bull run can bring again good profits for us home/small miners
Another thing I wish (just wish ok) ETC changes dag size to 5gb to kick out Asics

And Ethereum Classic does not plan to change the size of the dag file so that this coin can be mined by more miners.
