how that reflects to miners payment, depends on the share reward method.
That would happen is time between blocks are short compared to time for difficulty change. What about if difficulty change more often than time between blocks? If N is PPLNS is big enough the pay will be roughly the same.
the diff can't change more often than blocks, and there is always some smoothness in diff changes.
I saw https://miningpoolhub.com/ earns a lot in miningpoolhub.com. .037
Now it earns only .014999
So I mine when it worths .037. Quickly quit when it drops. However, I wonder if my hash really worth .037 BTC/Ghday when I send them? I would be sharing my rewards with those that mine when the value is lower.
Looks like I did make a bit of profit.
The share difficulty is negotiated between your mining software and the pool software - is is not related to the coin / algorithm difficulty. The purpose of varying the client difficulty is to ensure shares are submitted regularly, but not so frequently as to create unnecessary load on the pool.
When a block is found, the pool software will assign the block reward (minus fee) proportionally across all miners holding valid shares. The definition of a valid share will vary somewhat based on payment model the pool uses.
I am aware of that.
That is not the issue.
Anyway I am thinking of finding pps pool.
Is zpool pps?
