You forgot to tell people about risk of rising difficulty. It's not 385$ a month forever, if difficulty will go up (as it steady goes up every month) you will mine less.

And you can't get 230 MH/s with 7x GTX 1070 with 1kw of power draw. More like 215 MH/s and with around 1.2 kw. I know because I have mining rigs with 7x GTX 1070s.

People constantly seem to get into mining by looking at the calculator at CryptoCompare without reading the last bit which states that "Block reward is fixed at 5 ETH and future block reward reductions are not taken into account."

Using CryptoCompare and assuming your 230MH/s of mining ability will net you $470 a month (at current ETH of $165.47) people assume they make $5,640 a year. That sounds great!

If, however, you use something like MyCryptoBuddy's calculator, which takes into account pool fees and difficulty increase, you realize you're only going to make $1,553 in a year. Which is a rather paltry return if you shell out for 7 GTX 1070s.
