At nice hash I am consistently finding at least 4 blocks per week, often as high as 8
Nicehash uses your hashrate to rent to other people. Those other people are mining altcoins with your hash rate. So those blocks found by your miners are for altcoins with lower difficulty and not for Bitcoin.
I hope you realize that I am being compensated at nice hash, albeit at a low but steady rate, but not at all at private mining pools. So my question is not really about nice hash, rather about the private pools. Why cant I find blocks at the private pools, when I seem to find them so easily at nIce hash?
