mining ether will be proofitable in 2018, buy red cards rx570-580 and mine dual, wait pump and dump all mined coins
I do mining ETH with the RX 470 cards and i have 5 cards starting now. I have connected it with the nanopool mining and having claymore miner software in windows platform.
Since there is no crash issue in the time of restart or power cut.
I will be able to make around 360 USD including power charges, I have the power charges for 7 cents and then low. So i see it profitable to me. If someone shares their personal opinion, that's more informative.
