Thanks for going through it. So I buy 3 Radeon RX 470s i should be making 91.90$ a month not including pool fees? But then why have I heard so many people saying mining is no longer profitable when with less than 1000$ of equipment you can make over 90$ a month?
they don't want the diff(the absolute diff on the whole crypto not just eth) to increase...
Like Amph said they do so to keep newbies out of buisness so difficulty won't go higher ,but you realy got it all , according to current price and your $/kwh and difficulty you are going to make a profit , but what is really true about mining is that it needs alot of patience
