Under the high difficulty level of the whole network, most old bitcoin mining machines have fallen below the shutdown price

According to the latest data from F2Pool, at the current electricity price of 0.06 dollars/kWh, most old bitcoin mining machines have fallen below the shutdown price and entered a large loss area.
The data shows that the shutdown price of Ant S19, S19j, S19Pro, S17 series, Avalon A13/A12 series, Shenma M20/M30 series and other models is generally around 90,000 to 100,000 US dollars and above, and the daily net income is negative, which has approached or reached the shutdown level. In contrast, the new generation of high-efficiency liquid cooling models still have obvious advantages. Among them, the shutdown price of Ant S23Hyd. series is about 32,200 US dollars, and it still maintains positive income. The shutdown price of S21XPHyd. and other models is in the range of 4-50,000 US dollars, and the anti-risk ability is significantly higher than that of backward models. The industry believes that with the high difficulty of the whole network and the expansion of the efficiency gap of mining machines, the current cycle is accelerating the "stratification of old and new" mining machines, and it is difficult for backward models to maintain profitability under the existing market conditions.
