Yeah, unfortunately I agree. If those are accurate predictions it only further proves ASICs will never see a ROI. There's a nice 1.2 Th/s machine I could get my hands on but unless I get it tomorrow it doesn't look too promising.
Thanks for your input odolvlobo! Honestly, I thought this topic would be more popular.
You can't make a blanket statement like that because a positive ROI depends on
three factors: difficulty, cost, GH/s
Most people will lose money buying because they haven't paid attention to these three factors, but it is still possible. On the other hand, when a lot of people mine at a loss, it is hard for anyone to mine at a profit.
