What Marcoi said is true to calculate today's ROI.
Last year in, I started mining XMR, I was too caution and too slow to ramp up number of machines.
I was making may be $1 to $10 a day, or mining 0.7- 0.9 XMR per day with 8 x E5-v3 miners.
You see where I am going,
Today, XMR is over $150 , 8 x E5-v3 miners would net me less than 0.1 XMR per day.
Unless you have a crystal ball, Cryto mining is like buying lottery ticket.
