Re: Ethereum mining still profitable?

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.,

Real stupid miners, you mean. UNDERVOLT and overclock.

It depends on the graphics cards. I usually undervolt and underclock to get better efficiency as I have high electricity price.

Because you have sense. Overvolting is almost always done for "vanity" hashrate records, people who don't care, or people who simply have more money than sense.

I also undervolt my 7970. The difficulty is still rising. I might have to undervolt and increase the efficiency again.

I use the AMD R9 390, I undervolt it to below 1000 mV and frequency is around 970 MHz. It is quite efficient.

It is quite efficient if you under volt and under clock. But if you pay high electricity price, it will not be profitable soon.
