You are guys lucky that you are living in the place with low electricity rate. Here in the Philippines, the rate is almost 0.27 cents. If we are mining with AMD cards almost 50% electricity bill, unlike Nvidia card that you can lower the watts while the hashrate is higher.

AMD cards even if it's undervolted it can only reduce a small power consumption.

Do you think guys it's still profitable to mine ethereum with AMD cards? I use some calculator, but it takes years before that I can break even and get the return amount of my investment.
