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 if you're trying to uninstall it, you have to do so through Control Panel. Apparently from what I read, BH auto-updates so that could be the cause.
