The profitability is the same for eth and etc.
But I think soon etc will be more profitable because the most miners are on eth now.
Can't see the logic in your words. It doesn't matter how many miners are on eth. The difficulty means nothing alone, it should be compared to price to make any sense.
what he want to say is that with ETH going pos, more miners and money will go to ETC and will be more profitable to mine, and i agree with this
