The article discusses the challenges faced by Bitcoin miners and the role of pool mining in addressing these challenges. It highlights the unpredictability and variability of mining rewards due to the statistical and random nature of finding blocks. Pool mining allows miners to collectively mine as one entity, increasing the chances of finding blocks and ensuring more frequent payouts. However, pool mining introduces its own sources of variance, such as luck risk and transaction fee fluctuations. The article also discusses the Full Pay Per Share (FPPS) payout scheme, which provides miners with predictable and stable payouts but requires pools to have high capital requirements and results in higher pool fees. The inherent unsustainability of FPPS is highlighted, and the article suggests that alternative payment schemes and risk hedging strategies may become more prevalent in the future. Overall, the article emphasizes the need for miners to explore different approaches to maximize their profitability.
