S9 is pretty old in term of ASIC. The current ROI is really high if you find one of those. They hardly make 10$ per days.
You must be really early in the game when it comes to ASIC miners...

S9's can't get old unless a better version comes out. S9's ROI time is low because bitcoin's price is not high enough.
Don't look at other mining hardware while making comparisons. Nobody would buy L3+'s If ltc was still 4$. Same goes for eth and gpu mining.
You'll never know when will btc take its market dominance back. What'll happen to those alts then?
Yeah, you are right, but the current 220+ days for ROI is a really long time. Of course if the bitcoins skyrocket to 5000$ then that would be a very different story !
