I started recently mining VTC and MONA on Mining pool Hub and noticed that while my hash rate is around 210MH/s, on mining pool hub it is keeping on fluctuating between 60 and 90 MH/s only
I'd watch out with the cryptomining-blog ccminer link. Comments on the page show it comes up as virus (same for me) and people had coins stolen after using this download.
Yeah it gets virus flagged so I'm taking a risk making an exception for it. But I think it's very likely a false positive and if it isn't I won't lose too much. I'm seeing much better real hashrates on the site so it is definitely working better.
