⚠️ Calculating with an electricity cost of $0.08/kWh and a 5% mining pool fee, the current mainstream mining rigs—Antminer S21 series—have hit the shutdown price. Only a few high-end new models are still profitable, with a shutdown price of $44k. 2018: Bottom at $3,200, mainstream miner S9 shutdown price was $4,000. 2022: Bottom at $15,000, mainstream miner S19 shutdown price was $18,000. So here’s the question: if we stick to the same logic— In 2026, with the mainstream miner S21 shutdown price at $69,000, does that mean this cycle’s $BTC bottom is $55,000?
