A couple of mistakes in there
Time isn't (usually) a factor in rewards.
If the pool hash rate halves, then the pool will find half as many blocks, but your reward per block will double.
The factor that is relevant is difficulty.
As difficulty increases, your expected reward decreases in proportion with the difficulty increase.
Also as Phil has said, electricity cost is one of the main big factors in determining your return.
The other main ones are cost of hardware and reliability of hardware.
Aside: Time becomes a factor if we don't find enough blocks per difficulty change, since then more of your rewards are affected by later difficulty changes.
Thanks kano, and phillip. You are right that the given information is not complete. It was quite late yesterday as I wrote that.
I do understand the energy cost is the main factor here together with the infra cost to hit ROI asap so that's why these 2 variables are important in my opinion.
1/ The first column is average number of hours to find a block by the pool (and get paid). Energy price is a given data. it's a constant practically. there is not much i can do about it at this point so the variable that makes me make profit or not is actually the number of hours that the equipment takes to make coins. (the point of ignorance on my side is if the number of hours you are mining affects the amount of money you make. My understanding is that only the relative hash power to the pool (column2) and the speed in which blocks are found are the 2 main variables that determine how much I make per day in average.
Why am I considering mining not a long run thing with this data? because the curve shows increasing times in the pool. (I know luck is a variable but as you cannot affect it it's wise not to think much of it)
2/ The second column is average number of hashes to find a block, as I know how many hashes/s I have this tries to measure how un/important is my share of work and how it's evolving given the difficulty. That is, how many calculations are actually made for one reason or another in every block as average. This column is not nice in my opinion and affects you infra investment as in a very short period it's in its way to double the numbers from the summer and, as mentioned in my previous post, there are quite a few more s9 comming in shortly.
Why am I considering mining not a long run thing with this data? because you want to keep up with lineal slope of this trend to make the money you were making yesterday.
seeing this in the table is quite arid, I know, unfortunately I cannot upload a pic of the graph to illustrate the points at this moment.
So that's my thinking. I understand they are not the traditional mining ratios but I dont think that it means necessarily that they are not representing a reality. But again, i might be wrong.
