Yeah Bitcoin is deffo not viable now GPU wise.
I have deducted electric costs from my profits.
Basically, at the moment I get around £12 a day from my 3 cards. Lowering the power on the cards my 1080 use around 125watts each and my 1080ti around 150 so 400 in total. At 14p kWh it's around £1.50 a day.
So at the moment I get just over £10 profit.
Using Nicehash tho they currently pay me around £10 a day then less the £1.50 for the cards but I mine it myself (which takes a while to setup but you get a better return as seen above)
