...Well I don't know if you've looked up the profits that the Antminer L3+ ....

And why would I look up the profits of an X11 miner for a thread about a SHA-256 miner?  

...So you're saying that as soon as you have your mining equipment payed off (you hit ROI) ....

No one that knows what ROI stands for (Return On Investment) has ever said that.

Is there a Neoscoin Wallet out there that will run/build on Ubuntu 16.04.1 LTS and can be solo mined against?
Every version I've found either has seemingly unsolvable dependency issues or just flat doesn't work.

It's not actually solo mining, but I did manage to get something "working".
Mining alone in a crappy UNOMP "pool".
It's ugly, but I'm not giving away coins anymore.
