Where am I pointing these cards?
KawPow looks to be the most profitable on whattomine but 10 dollars a day from 100 cards?
Is there anything else that may fetch more profit?
If you want to get the best profit, then choose the most profitable coin. Today it is DYNEX (DNX)
https://hashrate.no/gpus/470Mining this coin is good because video cards do not overheat and in this mode the power consumption is less than when mining coins using the kawpow algorithm.
The best profit is $13 per day, but I don't believe that all your video cards will work perfectly. These video cards have a lot of cooling systems without gas and other problems, so the next 2 months will be very busy for you to set up mining and remove defective GPUs.
