I'm surprised by the fact i can 'only' mine around 20 ETN per day which is around $4 per day... This is so little money, are there really people in the western world that keep their PC mining for this little money? Am I missing something in my calculation?
First of all, nvidia cards are no good for cryptonight algo. Similarly priced rx 570/580 would do 850-1000 H/s. And second, $4/day means you'll get the price of your GPU back in ~ 100 days. How many businesses in the "western world" do you know of that can give you complete ROI in 100 days? A few years used to be a good solid business model.
