Hi Andre, thanks for following (upvote would be also great ;-).
Now to your question: I get with 1770 h/s ca. 3 ZEC / month. It's not to calculate in €... 3 weeks before ZEC was almost 400US$ like ETH... That's 1200 US/month. Means in 3 months it's the break even. If it goes up, even faster. If it goes down, longer...
So the calculation is not like this. But I will explain in my tomorrow's or after tomorrow's blog (see 1/x)
And btw: 1700h/s is for one RIG and not so strong cards. With 6 rigs you do the 6x 1700h/s = 10.2 MH/s and that's a LOT !! (ca. 18 ZEC / month) x 400US$= 6400 US$ more peformant cards=more ZEC
Until then, enjoy and vote, reply, resteem and follow ;-)
Thank you !!
