I have always mined at Brains (formerly Slush Pool).
I am getting ready to withdraw my coin from it soon, and decided to shop around the pools. I never really thought there was going to be a drastic difference from one to the next, but I used the calculator on White bit's pool and it's showing a 20% difference in my rewards.
Is this accurate? If so why such a difference?
I realized I'm getting more per block, but they find less blocks. Shouldn't it even put in the end to be about the same amount of rewards?
What am I missing?
At what interval did you make comparisons?
At a short interval of several days, you can notice a difference of 10-20%, but the longer the mining interval, for example, six months, the smaller the difference will be.
And you need to compare pools with at least approximately equal hashrate.
