I think Kano is right on the point,
but the OP just doesn't understand or want to understand anything he says.
Well long ago and far away I mined on bitminter.
I stopped and moved to other pools.
The reason was back to back 99+% blocks.
The odds on that are about 11000 to one.
But it happened.
Now if a 100% pps pool comes along like this and it rips back to back 99% cdf blocks it has to pay out 7 blocks while it only collected 2. That is a shortfall of 60 coins.
So if you want to mine here and risk that he can’t pay when he has a down streak go for it.
By the way does anyone know how much hash he has on hand? 1ph 10ph 20ph or whatever.
