How Does a Bad Luck Streak in PPLNS Differ in Impact from One in PPS?
In PPLNS, a bad luck streak directly reduces the miner's payout, as rewards are only distributed when a block is found. In PPS, the miner's payout remains fixed because the pool operator absorbs the risk.
Therefore, the impact on the miner is a direct, immediate reduction in income in PPLNS, but only a risk to the pool operator's reserve fund in PPS.
