How in hell we have those new comers in a fucked up profitabilty like this ?! , you see i am not asking a newbie shit question , there is a new situation this time
C'mon, you are a miner, you know hows difficulty work. When each coin will re-targeting the difficulty, what things that affected the difficulty and so on.
Refer to your question about newcomers, means you believe that difficulty increased caused by network Hashrate was growing effect from newcomers. And why in this current situation a ton newcomers coming.
My question is, which coin are you talking about? Take a look around, man. Not all coin increase on its diff. Diff increasing related to a few things, and one of those things is "how much hashrate on coin network", right? It's simple, let me give you an example. When miners who mine coin X, then, most of them left coin X to mine coin S. So, soon the difficulty of coin X would decrease, and the difficulty of coin S would decrease. Yes, many newcomers come at this moment, but they, not one only reason that the diff increased.
So the answer that makes sense related to your questions was:
Your profitability decreased at this moment just because its coins price has fallen, and your hardware seems pretty good enough for today, at least until the end of this year, who knows right?
