please someone tell me like i am 10 years old how on earth do the different pools have such diffent payouts. I thought all pools would want to go for the most profit mining so why are some like 30% less than competitor pools. Im not trying to be a ass it is a honest legit question and i appreciate the honest answers i get thanks
If we are talking about multipools, determining what's most profitable and taking advantage of it requires knowledge and skill and fast connections and servers and timing and luck. So the pool that finds a low difficulty profitable coin and switches to it quicker, then has enough hashrate to find blocks before difficulty skyrockets but not too much hashrate to crush it, then dumps it for BTC at a good rate, will be more profitable. Usually it's not likely for a pool to consistently outperform all others by a large margin because there is no magic to it and somebody else eventually will figure out whatever technological advantage there might be.
If we a are talking about single coin pools then it's mostly just luck.
NiceHash is neither of those, it's a rental service so whatever the renters are mining and willing to pay for it might not necessarily follow the above.
ZenPool - nobody knows what that is.
