Yes, it is alive, if build your rig with gtx 1070ti ( which is very balanced with it features, imho) you can get about 3-4 $ per card depend on the coin and difficulity..
So I guess the current ROI time is about 6 month which is rather ok...
Not true. Half that amount according to whattomine. Below $1.83 after electric or $2.26 before electric cost for zcash. Plus irs taxes it as income right away and also later if you cash out further gains later. It's about $1 a day per gpu. Not worth baby sitting your rig . Mining is for losers. Best to buy coins especially now while prices are depressed
I mine and what a dumb mistake, I can't even go on vacation. Only good thing is that gpu went up in value. So far that's where the real money is at.
