he isn't lieing, it can be done, my 1070's get average 8 bucks a day, my 1080ti's above 10 is common.  It all depends on what time you put for profit and pool switching and what algo's you choose and system stability.

Although I would keep Phi in the mix though cause it does have spikes of profitability during the day.  The more algorithms you have to do profit switching the better, but this causes systems to become unstable too mainly because you need to cut down the interval cycle times for checking profitability of coins, I'm down to 3 minute checks some of my rigs go down at times, 100% positive its because of core voltages, and specific algorithms.  I haven't been able to track it all down yet, because its pretty complex to do and its happening on many different coin switches but seems to be when switching to nist 5.  Each coin overclocks and undervolts are different, so finding out is tricky.

You really need to know how awesome miner works to add in the most optimal miners for different coins and update them regularly.

You don't need a programmer for this, the guy that is complaining, just doesn't want to do the work, he should pay some one to do it for him, Awesome miner is not an expensive program for the amount of people that use it.  Its not like MS office that has millions of users world wide, its one or few devs making a program for a few thousand people, and charging not much for it.   So, don't complain if you can't figure out how to use it.  Just load it up and keep going at it or ask questions here to and figure it out!
