I think the current difficulty has hit profitability hard since the fork, My earning has dropped severely.
I could be mistaken but i speculate that the high difficulty could work against the miners.
Difficulty of the math problem adjusts so the solutions are found every 2 minutes on average. That's how PoW crypto works. More miners, higher difficulty. Its miners against other miners.
I'm not sure why you feel he needs a basic reminder of how crypto works. He's saying that his profits are down, and he suspects its because of the difficulty. There's nothing incorrect about his statement. I've made the same observation many times.
My question remains, with rising difficulty and more GPU miners, how will UPX equalize hash rates for android and IoT devices? I know android is much faster now. So is GPU reportedly. What exactly are we gaining here?
Quote: "I could be mistaken but i speculate that the high difficulty could work against the miners."
That sentence is not what someone who knows how crypto works would say. More miners coming in, increases the difficulty. That's how PoW works. Its miners going against other miners. It's a feature of the system. If more miners come in, hashrate and thus the difficulty will increase and you will earn less coins than before, unless you add additional hardware.
Now, how much this algo has equalized GPUs and Phones/IoT, you'd have to compare the hashrates of before and after and see what kind of increase each device got and work out the difference.
On a GPU i got an 8x increase for example. If you got more than that on your Phone, then there you go, you're more competitive than before.
I may not be an expert but my understanding of how crypto works is fine. What you mistake for an ignorant statement was actually a personal observation, clearly explained in the previous sentence.
My observation was that : After the fork, I noticed a sharp decline in my daily earnings. I speculated that this was probably due to the difficulty being disproportionate to the short time after the fork and the hashrate being produce on the hardware mining on the new algo.
After most forks the difficulty should be very low and increase slowly over time as more and more hash hits the new algo.
So before you start insulting my intelligence perhaps you should read more carefully and understand what the person is saying no?
