So I suppose Bitmain will have a blast this New Year for the $400 extra we have paid on the 2.65 BTC batch!!!

Ok, so you tell me how one Ant is supposed to mine 0.45 BTC in one day, because that is the difference on delivery for the 2.65 and the 2.2 batch!!!
Well Lets say this. IT sure take longer for them to answer a simple message than that iT would take an antminer to mine 0.45 btc
As i said the man is wise and good businessman and he knows his math well
