⚠️ Based on an electricity price of $0.08/kWh and a 5% mining pool fee, the mainstream Antminer S21 series has already reached its shutdown price. Only some high-end new models are still profitable, with a shutdown price of $44,000. 2018: Bottom price $3,200, mainstream S9 shutdown price $4,000. 2022: Bottom price $15,000, mainstream S19 shutdown price $18,000. So the question is, if we follow the old model— Will the mainstream S21 shutdown price reach $69,000 in 2026, and will the bottom for $BTC in this round be $55,000?
