A friend of mine is lucky enough to have a lot of money and he is asking me info on entering the mining world. He wants to mine more than buying bitcoins.

I have checked the forum and many other websites and it is my understanding that he can't buy anything and start mining right now. KNC is sold out and Cointerra has only the March batch available. Is this correct? Is it also correct that no other hardware would make sense right now? For example, he could buy a bunch of Asicminer blades but I don't think that would be profitable, even if he buys 50 of them.

Thanks a lot!
