If you are only looking at the front page of whattomine (and even the coins page), you are missing a significant part of the mining market; and also some of the most profitable. They don't list skein, skunk, tribus, nist5, hmq125, x17 and others; each with coins that can be more profitable day to day than those listed on the front page. Hell, skunk (SIGT) has been above it for days if not weeks and 1080ti's kill it with that coin.
You should use whattomine as the baseline to show the MINIMUM you should be making with your rigs, with MINIMUM effort. Then if you want to put in the effort, you can make more, but you need to keep an eye on the forums and markets so you are maximizing your profits. You also need to consider the rise in value of new coins . . . lots of people have made a lot of money on SIGT because they got in early. If I count the gains on that alone, its $100+ a day for my rigs. But that takes work and paying attention to the market and community.
A lot of misinformed or ill-intentioned people will say they make 50%+ more than the best profits in whattomine. That's a lie. Mining only becomes more profitable if the price rises through community adoption. There is no such thing as a "secret" coin no one knows about that is making better profit than everything on whattomine.
thats what im doing, i dont care about earning 3$ dollars a day, im trying to find coin with some nice rise in the future. But the crypto market is huge, this is incredible how much coins are created, that make it difficult to choose one....
