You're obviously doing it wrong. Mining isn't just buy-plug-sit-profit. It takes time, dedication, effort, research and passion. Real miners understands this.
Yep.
If you just look at the daily profit of whatever you're mining, then you are doing it wrong. It's like looking at the hourly BTC chart. Oh it's going back up, bullish! Nope...if you look on the daily chart, it sure as shit isn't. But it will, at some point.
You need to look at mining (and whatever you are mining) in a longer time frame. I have stopped mining what everyone's mining a long time ago. I mine coins that I can see a future for or that will turn into POS or MN coins at some point where I can turn profits without my GPUs. I think it's too early to call GPU mining dead, but I'm not buying GPUs at the moment unless they are really cheap. Whoever forks out 1k usd or half a grand for a 1080ti or an RX is just stupid, sorry.
I'm still turning profits even when I pay about 0.20$/kW
