Do they really exist , is there a private miners that we don't know about it pulling 2 to 3x what is public miners doing on the same gpus.
I can see on the pools some miners with crazy speeds i can't imagine that they are using such amount of hardware to get this speed , it seems also that the cards are not really loaded when i run any of the public miners like claymore or sgminer .....just asking if there is really something like that..
