According to André Dragosch, PhD (@Andre_Dragosch), solo miners are questioning whether achieving 688 million shares is a positive performance metric. In the context of crypto mining, a higher number of shares generally indicates significant hashing power and prolonged mining activity without finding a block, which may suggest higher network difficulty or less mining luck for the solo miner. For traders, this data point signals increased competition and potential shifts in mining profitability, which can impact coin supply dynamics and price action for cryptocurrencies like Bitcoin. Monitoring solo miner performance metrics such as share count can provide insights into network health and mining centralization, both relevant for crypto trading strategies (source: André Dragosch, Twitter, May 22, 2025).
