No no
ETH not profitable anymore to mine
Except you got free rigs and electricity

true statement, if you pay over 40 cent per kwh of energy. most of us pay 15 cent or less, so ETH mining ist still profitable atm

If you use some kind of undervolting and reduce the frequency of the core or memory, it is still profitable.

Miners tend to overvolt and overclock. That will make their ROI faster if their electricity price is low.,

The difficulty of the ETC+ETH is still rising even at the uncertain times. It seems people are very confident.

The hash rate for the Ethereum is at a new all time high now. So the big miners think the price will rise again.

It looks like it. There are more hashing on the Etherum, even though miners might now ROI in the future.

Most of the new hashing are from the cheap electricity big farms. They will ROI as their total cost is lower.
