I think all these ASIC miners are teetering the line of a flat out scam/fraud because they become not profitable very quickly unless your lucky you may never ROI unless you mine a coin that just comes out and it spikes really high, I think all these companies making asics will go out of business I really think POS masternodes and the voting sytem POS (don't know the proper term) will eventually replace POW mining in general but for now I think if you can't mine with a cpu or gpu then I won't mine that coin ASICS are pure shit IMO
