PANews reported on December 2nd that, according to the latest data from F2Pool, with the current electricity price at $0.06 per kilowatt-hour, most older Bitcoin mining rigs have fallen below their shutdown price, entering a period of widespread losses. Data shows that the shutdown price for models such as Antminer S19, S19j, S19 Pro, S17 series, Avalon A13/A12 series, and Whatsminer M20/M30 series is generally around $90,000 to $100,000 or higher, with negative daily net profits, approaching or reaching shutdown levels. In comparison, the new generation of high-efficiency liquid-cooled models still have a clear advantage. Among them, the Antminer S23 Hyd. series has a shutdown price of about $32,200 and is currently still maintaining a positive return; the shutdown price of models such as S21 XP Hyd. is in the range of $40,000 to $50,000, and its risk resistance is significantly higher than that of the outdated models. Industry insiders believe that with the network difficulty remaining high and the efficiency gap between mining machines widening, this cycle is accelerating the "stratification" of mining machines, and outdated models are finding it difficult to maintain profitability under current market conditions.PANews reported on December 2nd that, according to the latest data from F2Pool, with the current electricity price at $0.06 per kilowatt-hour, most older Bitcoin mining rigs have fallen below their shutdown price, entering a period of widespread losses.
