What Is a ‘Bad Luck’ Streak for a Mining Pool?
A 'bad luck' streak occurs when a mining pool takes significantly longer than the statistically expected time to find a new block, given its current hash rate. For example, if a pool should find a block every 10 hours but goes 20 hours without one, it is experiencing bad luck.
This period results in lower-than-expected revenue and can strain the pool's reserve fund, especially under a PPS system.
