Nicehash and westhash are highway robbery there is no way you can make a profit it is all BS do the math.
You are saying this from buyers point of view? Me, as a seller, I constantly make profit, small, due to high electricity cost, but more than mining direct Bitcoins.
I make a profit as well ... when the price is right. Right now the price is wrong. I'm not sure who would rent their rigs at 4% - 2% = 6% less than you'd get mining at a place like Eligius, where at minimum you make 99%, more if you configure your NMC.
Renters need to get their prices right...
