That's quite a lot with only 4Mh/s.. I have 8.8MH/s and earn about 0.017 in 2 days with X11. Mining straight on tmb.So miningrigrental is not the same as betarigs?
I'm gonna check miningrental.
I have another 7 mh/s dedicated rig and three 1.5 mh/s gaming computers which I don't have selling all the time unless it's late at night (but they are still configured the same way, just marked unavailable for renting but they still mine through miningrigrental.
