ETC has a network hashrate of 5TH, ETH has a network hashrate of 250TH.
It is assumed 50% of that 250 is 4GB or less (Gpus or Asics).
ETC mining profitability with drop like bricks if they drop the DAG and all that 125TH hashrate shifts to it - could even be higher if the already offline 3GB gpus join in.
Network hashrate will go from 5TH to ~130TH - thats a 2600% increase and will see a proportional difficulty increase, tanking profitability , so no, its not really an alternative.
Yes the profitability will tank but it won't be by that ratio, most likely it will have a profitability slighty higher than Ubiq and maybe between $0.50 profit per day before electrical costs. So obviously if you got $0.10/kwh power it won't be worth it but many around the world got power cheaper than that and they will still mine it.
Looks how many Dagger forks there are and the underlying coin has such a small miner reward yet there are still tons of miners. So the profitability will be horrible but I guess it would at least secure ETC's network from any more attacks.
