What you are rewarded per block is related to your fraction of the work.
If you are on a pool that averages half the number of blocks we do, then you'd expect to be rewarded twice as much per block, if they had the same fees.
i.e. you'd average half as many rewards, but twice as much per reward.
If you are on a pool that averages twice as many as we do, then the opposite is the case:
i.e. you'd average twice as many rewards, but half as much per reward.
Really what mattes is:
1) The pool fees
2) The pool is 'big enough' to not undervalue your shares
On my pool, all BTC that comes in to the pool, 99.1% is rewarded to the miners.
Over time we of course expect to average 100% luck + block txn fees - orphans, so you are expected to get greater than any long term PPS pool reward.
On nice hash they give you ~94% of the money they get from the people who rent your miners.
They keep ~3% of what the renter pays nice hash, then they give you ~97% of what's left over.
i.e. they charge you a 3% fee and the renter a 3% fee.
So nicehash is only paying you more, on average, if the person renting your miners is willing to pay ~6% more than you would average mining on my pool.
At the moment the 'expected' reward, based on the tx fees for the last 9 days, which have dropped since last month, is 99.1% * 105.6% - orphans
i.e. 104.6% PPS - orphans if we get any this month.
That's the continuous 'expected' reward on my pool at the moment.
As a miner, renting their miners on nice hash, to get that continuously on nice hash, the person paying to rent the miners would always have to be paying more than ~110.9% PPS
Now if you can find someone - all the time who is willing to pay more than that to rent your miners, then you'd expect, on average to be ahead of mining on my pool.
There's also the actual rewards for the last 7 months on my pool, that have averaged 124% PPS on my pool, but that's just luck ... for 7 months
