Slut hashes of MRR and NiceHash made it profitable last week. And profit was for puppet masters only. Look for now. And yes, I tried. If you look on the main pools (those guys who submit most of the network blocks - pool sexy block explorer helps) of network and their powers you can understand what is wrong. Total network hashrate is a fiction. Real is in about 10 times less. With sky real difficulty (it is not a fuction, of course).
