ROI discussion was: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
...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?

No one that knows what ROI stands for (Return On Investment) has ever said that.You cut off the rest of my original post in which I was speaking of Litecoin as well, and I'm also not here to argue semantics.
How about you try to be constructive?
