You seem to think you are proving me wrong because a week ago you were making $29/day rather than $19-22/day, but that only makes the downward trend in earnings even worse... I shall refrain on commenting on what this says about your mental faculties.
Your a legend in YOUR own mind, math challenged maybe.. not my place to judge. Meanwhile I'll keep taking the 6.50 which is more than your doing no doubt.
You're comparing apples and oranges again, but even still it is not correct that the X3 out-earns a comparable costing GPU rig in all cases. I have a 4x RX 560 rig that does only bring in $2-$3/day depending on what I am mining (Ethash or CN-variants), but the GPUs also only cost $640 and it has been earning this amount - net of electricity, mind you - for several months now. Similarly, I have a 6x GTX 1060 rig that has been earning $7-$11/day mining ZEN (Equihash), so /more/ than your X3, and its GPUs cost $1560...
In fact, both rigs have already paid for themselves while the GPUs are still selling used on ebay for not much less than what I paid for them; in contrast, a cursory glance of the ebay listings for the X3 shows one with a BIN price of $850, and after DERO forks next week even that will appear to be a princely sum for a not-terribly-attractive doorstopper.
Finally, you are basically stuck with mining BCN now, which is pretty much the original shitcoin: it's been around for 6 years and the all time high price was less than 2 cents!
Earlier in this thread you said - more than once, actually - that you have, "all the time in the world," to ROI on your X3; that is looking more and more like a prophetic statement with each passing day. But you keep yelling, "WRONG!" if it makes you feel better; I won't judge.
Let it go. He'll never understand how gpu rigs work, he thinks they all make $2.
