Thanks UserU for responding to me. The other post wasn't really a response. If the payouts are lower, OK, it's not a scam, but my hash rates are being "taken" by minergate then.
Yup, it's more for beginners that are new to mining (and are not aware of the higher fee or they don't care much).
About your last post, I haven't installed BH so I can't relate but apparently from what I read, BH auto-updates so that could be the cause.
Thanks. I couldn't see a place to turn this off. Anyone know if Nicehash does automatic update or if you can turn that off?
