Antpool data reveals that under the current Bitcoin mining difficulty and an electricity cost assumption of $0.08 per kWh, several mining rigs are nearing their shutdown prices. Models such as the Antminer S19 XP+ Hyd, Whatsminer M60S, and Avalon A1466I are close to this threshold. The shutdown price for the Antminer S21 series, including S21, S21+, and S21 Hyd, ranges between $69,000 and $74,000. Additionally, high-performance models like the Antminer U3S23H and S23 Hyd have a shutdown price exceeding $44,000.
