Mining doesn’t actually work this way. Think of Bitcoin mining more like participating in the lottery than solving a puzzle. Using this analogy, the odds of winning a lottery are established using the total number of tickets bought, where each Bitcoin miner owns a portion of the total number of tickets equal to the percentage of hashing power that they are contributing to the pool. The goal is to have someone “win” an average of every 10 minutes.

Think of PEGA-Pool much like large lottery, with each block being like a new lottery round (the outcome is completely independently of any previous round). Let’s suppose that PEGA-Pool is expected to discover blocks roughly every 4 hours, but sometimes we’re unlucky and it takes a bit longer. Regardless of whether several hours or mere minutes have passed since we last discovered a block, the odds of locating the next one remain the same. This would be because PEGA-Pool is continuously purchasing new tickets for each lottery round.

It wouldn’t make sense to quit based on past luck, just like it makes no sense to mine at any specific pool just because they were lucky this week (or run out to buy lottery tickets just because a few people hit it big this week).
