Did you factor that difficulty increases every 13 days?
June 30 is estimated to be 17 Billion already.
In 5 months will be 90 Billion
Yes, every 13 days with a conservative(perhaps too much) 20% diff jump..the numbers actually showed him earning 24-26 BTC at most FOR ALL 4 NEPPYS by mid dec 2014, meanwhile I had one order that I refunded back in may, for about the same amount of coin. Really goes to show how hard Kfc stuck it even with the meager 3TH, my friend had his hopes so high based on Kfc's earlier track record boasting they will have 5-6TH each easy..i feel bad for him because 40kUSD to me is alot of money...
Good Luck to All
